M.; Bernard, M.; Jubeli, E.; Yagoubi, N. published an article.Application of 3319-31-1 The title of the article was Characterization of the surface physico-chemistry of plasticized PVC used in blood bag and infusion tubing. And the article contained the following:

Com. infusion tubing and blood storage devices (tubing, blood and platelets bags) made of plasticized PVC were analyzed by spectroscopic, chromatog. and microscopic techniques in order to identify and quantify the additives added to the polymer (lubricants, thermal stabilizers, plasticizers) and to put into evidence their blooming onto the surface of the devices. For all the samples, deposits were observed on the surface but with different kinds of morphologies. Ethylene bis amide lubricant and metallic stearate stabilizers were implicated in the formation of these layers. In contact with aqueous media, these insoluble deposits were damaged, suggesting a possible particulate contamination of the infused solutions The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Application of 3319-31-1

On August 10, 2021, Deng, Man; Liang, Xueyi; Du, Bibai; Luo, Dan; Chen, Hui; Zhu, Chunyou; Zeng, Lixi published an article.Quality Control of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate The title of the article was Beyond Classic Phthalates: Occurrence of Multiple Emerging Phthalate Alternatives and Their Metabolites in Human Milk and Implications for Combined Exposure in Infants. And the article contained the following:

Because of the recognized toxicity and legislative regulation of classic phthalates (PAEs), the manufacture and use of PAE alternatives have rapidly grown. However, lactational exposure to these emerging replacement chems. remains unknown. In this study, 11 classic PAEs, 14 emerging PAE alternatives, and 24 of their metabolites were comprehensively investigated in human milk from China. Except for nine detectable PAEs, nine of the 14 emerging PAE alternatives, including three (1,4-DEHCH, 1,2-DEHCH, and DEHIP) not reported before in the environment, were first identified and detected in human milk. Total concentrations of nine detectable PAE alternatives were in the range of 0.252-16.1 ng/mL, slightly lower than those of nine detectable PAEs (2.12-34.1 ng/mL). Addnl., 12 of the 24 target metabolites were found in human milk. Total concentrations (4.41-138 ng/mL) of these metabolites were significantly higher than those of their parent compounds Our findings highlighted the considerable coexistence of PAEs, emerging PAE alternatives, and their metabolites, resulting in a complex “cocktail” of plasticizers in human milk. Preliminary risk assessment indicated no or minor risk to breast-fed infants, but long-term low-level exposure to the “cocktail” chems. is of emerging concern. This is the first identification of multiple emerging PAE alternatives and their metabolites in human milk. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Quality Control of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate

On February 28, 2017, Genay, Stephanie; Feutry, Frederic; Masse, Morgane; Barthelemy, Christine; Sautou, Valerie; Odou, Pascal; Decaudin, Bertrand; Azaroual, Nathalie; Armed Study Group published an article.Electric Literature of 3319-31-1 The title of the article was Identification and quantification by 1H nuclear magnetic resonance spectroscopy of seven plasticizers in PVC medical devices. And the article contained the following:

Medical devices are generally made of polyvinyl chloride plasticized by six authorized plasticizers as alternatives to di-(2-ethylhexyl)-phthalate (DEHP) classified as reprotoxic class 1b. These are acetyl tri-Bu citrate (ATBC), di-(2-ethylhexy) adipate (DEHA), di-(2-ethylhexyl) terephthalate (DEHT), di-isononyl cyclohexane-1,2-dicarboxylate (DINCH), di-isononyl phthalate (DINP), and tri-octyl trimellitate (TOTM). The main objective of this study was to propose a new method using 1H NMR spectroscopy to determine and quantify these seven plasticizers in PVC sheets, standard infusion tubings, and com. available medical devices. Two techniques were compared: dissolution in deuterated THF and extraction by deuterated chloroform. Plasticizer 1H NMR spectra were very similar in both deuterated solvents; dissolution and extraction provided similar results. The sensitivity of this method enabled us to detect and quantify the presence of minor plasticizers in PVC. In nine com. available samples, the major plasticizer was identified and quantified by 1H NMR. In six samples, one, two, or three minor plasticizers were identified and also quantified. DEHP was detected in only one tubing. NMR is therefore very convenient for studying plasticizers contained in medical devices. Only small quantities of solvents and sample are required. It is not necessary to dilute samples to enter a quantification range, and it is sufficiently sensitive to detect contaminants. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Electric Literature of 3319-31-1

M.; Wakeham, William A. published an article.Product Details of 3319-31-1 The title of the article was Density and Rheology of Tris(2-ethylhexyl) Trimellitate (TOTM). And the article contained the following:

This article presents new d. data and some rheol. studies on tris(2-ethylhexyl) trimellitate (TOTM) which has recently been proposed as a reference fluid for viscosity at high temperatures and high pressures. The d. data were obtained with the aid of an Anton Paar DMA HP U-tube instrument, covering temperatures from (328 to 423) K and pressures up to 70 MPa, and they are aimed at extending the temperature range of previous results. They are also used to check the effect of inter-lot consistency of the d. data for TOTM. The present d. measurements are compared with previously published data. Rheol. tests were carried out to complement earlier studies. Particular attention is given to the shear rate range of greatest interest for the proposed use of TOTM as an industrial reference fluid for viscosity: the tests include shear stresses up to 750 Pa and shear rates up to 4000 s-1 under atm. pressure. The tests were carried out using a Parallel Plate Rheometer AR1500ex10C4298. The results at 298 K corroborate the previous findings that TOTM is Newtonian below a shear rate of 600 s-1, which is entirely compatible with its use as an industrial calibrating fluid for viscosity. At shear rates higher than 600 s-1 a shear-thinning like behavior is observed The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Product Details of 3319-31-1

Martin published an article in 2019, the title of the article was International Standard for viscosity at temperatures up to 473 K and pressures below 200 MPa (IUPAC Technical Report).Related Products of 3319-31-1 And the article contains the following content:

This paper presents the results of an investigation into possible liquid viscosity standards to meet an industrial requirement for a liquid with a nominal viscosity of 20 mPa s at a temperature of 473 K and pressure of 200 MPa with a relative expanded uncertainty of less than 5%. There are no com. available certified viscosity reference liquids that meet this requirement. Four candidate fluids were examined: squalane, Krytox GPL102, tris(2-ethylhexyl) trimellitate (TOTM), and dipentaerythritol hexa(3,5,5-trimethylhexanoate) (DiPEiC9). Although none of these fluids satisfies all of the criteria, two fluids were identified as being suitable as International Standards for viscosity at temperatures up to 473 K and pressures below 200 MPa. These fluids are squalane and tris(2-ethylhexyl) trimellitate (TOTM), which at T=473.15 K and p=200 MPa present viscosity values of 5 mPa s and 10 mPa s, resp.

On January 1, 2018, Pan, Ye-Tang; Castillo-Rodriguez, Miguel; Wang, De-Yi published an article.Category: esters-buliding-blocks The title of the article was Mesoporous metal oxide/pyrophosphate hybrid originated from reutilization of water treatment resin as a novel fire hazard suppressant. And the article contained the following:

Flexible poly(vinyl chloride) (fPVC) composites undertake potential high fire and smoke hazards. Withal, com. flame retardant, antimony trioxide (Sb2O3), in application to fPVC is proved to be harmful anyhow. Meanwhile, corrosive HCl gas evolves inevitably from fPVC during combustion. In this article, mesoporous SnO2/Ca2P2O7 hybrid crystals with high sp. surface area and pore volume was firstly synthesized via a facile way by utilization of the chelating resin as the precursor. The composition and structure of the hybrid material were characterized by X-ray diffraction, scanning electron microscope/transmission electron microscope coupled with energy dispersive X-ray detector and N2 sorption isotherms. The results from limiting oxygen index, vertical burning test and cone calorimeter showed that the synthesized product reduced the fire and smoke hazards of fPVC and decreased the amount of HCl gas emission due to the combined impact of SnO2 and Ca2P2O7. Moreover, this novel flame retardant holds great potential to replace antimony trioxide and provides the promising manner to develop Sb2O3-free environmental friendly fPVC composite with low fire hazards. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Category: esters-buliding-blocks

On October 15, 2020, Liu, Geng; Pan, Jun; Xu, Xianli; Wang, Zhaohui; Cui, Zhaoliang published an article.Name: Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate The title of the article was Preparation of ECTFE porous membrane with a green diluent TOTM and performance in VMD process. And the article contained the following:

In order to mitigate the harm of solvent volatilization during thermally induced phase separation (TIPS), more and more green solvents/diluents were developed, produced and applied in the membrane field. In this paper, trioctyl trimellitate (TOTM), an environmentally friendly diluent with high b.p. and low vapor pressure, was firstly introduced to prepare porous membranes, especially hydrophobic poly(ethylene-chlorotrifluoroethylene) (ECTFE) membranes by TIPS. Effects of ECTFE content on the membrane properties, including morphol., pore size distribution, porosity, liquid entry pressure of water (LEPw), water contact angle (WCA) and mech. properties were characterized. Then the prepared ECTFE membranes were tested in vacuum membrane distillation (VMD). Phase diagram of this new ECTFE/TOTM binary system presented the existence of liquid-liquid (L-L) phase separation region when the ECTFE content was below 40%. The characterization results showed that the 15 wt% ECTFE membranes presented the continuous structure without the production of dense layer, but as the further increasing of polymer content, the spherulite structure began to be observed and surface became denser. Significantly, all the prepared ECTFE membranes exhibited excellent hydrophobicity. The liquid entry pressure of water (LEPw) and water contact angle (WCA) of 20 wt% ECTFE membranes reached 0.42 MPa and 139.9°, resp. Moreover, in VMD, the prepared membranes exhibited high permeability (permeation flux was 23.09 kg/(m2.h)) and separation (salt rejection was 99.9%) performance. The above results show that the prepared ECTFE membrane showed promising stability performance in long-term operation of VMD for concentration of salt solution The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Name: Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate

And the article contained the following:

This paper presents a reference correlation for the viscosity of tris(2-ethylhexyl) trimellitate designed to serve in industrial applications for the calibration of viscometers at elevated temperatures and pressures such as those encountered in the exploration of oil reservoirs and in lubrication. Tris(2-ethylhexyl) trimellitate has been examined with respect to the criteria necessary for an industrial standard reference material such as toxicity, thermal stability, and variability among manufactured lots. The viscosity correlation has been based upon all of the data collected in a multinational project and is supported by careful measurements and anal. of all the supporting thermophys. property data that are needed to apply the standard for calibration to a wide variety of viscometers. The standard reference viscosity data cover temperatures from 303 to 473 K, pressures from 0.1 to 200 MPa, and viscosities from approx. 1.6 to 755 mPa. The uncertainty in the data provided is of the order of 3.2% at 95% confidence level, which is thought to be adequate for most industrial applications.
