Detection of vapors from overheated PVC cables with modified sea urchin-like ZnO for fire warning was written by Li, Zhou;Han, Jia;Chen, Wenjia;Yi, Jianxin. And the article was included in Sensors and Actuators, B: Chemical in 2022.Recommanded Product: 5444-75-7 The following contents are mentioned in the article:

Detecting the emitted vapors from overheated polyvinyl chloride (PVC) cables has proven to be an effective way to monitor early elec. fires. In this work, the vapors generated from both conventional and phthalate-free PVC cables were first examined 2-ethylhexanol (2-EH) was found to be ubiquitously present and can serve as a universal signature gas for the overheated cables. Sea urchin-like ZnO was then prepared via a template-free hydrothermal route for sensing 2-EH. A facile immersion-calcination method was adopted to further modify ZnO, and different CuO/ZnO and Cr₂O₃/ZnO composites were obtained. The surface modification led to significant improvement in the response of the ZnO sensors to 2-EH. Cable fire simulation tests were also conducted to evaluate the response of optimized gas sensors to overheated conventional and phthalate-free cables in comparison with a typical smoke detector. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Recommanded Product: 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 5444-75-7

Identification of odorous constituents of southern yellow pine and China fir wood: the effects of extractive removal was written by Liu, Ru;Wang, Chen;Huang, Anmin;Lv, Bin. And the article was included in Analytical Methods in 2018.Quality Control of 2-Ethylhexyl benzoate The following contents are mentioned in the article:

In this study, the odors of two types of softwood species, namely southern yellow pine (Pinus spp.) and China fir (Cunninghamia lanceolata (Lamb.) Hook.), were identified and extracted with ethanol-toluene for the removal of extractives. The odorous components of neat and extracted wood were identified via gas chromatog.-mass spectrometry/olfactometry (GC-MS/O). The results showed that about 40 key identified volatile compounds (peak area above 0.2%) were detected from the GC-MS data, and more than 50 kinds of odorants were identified using GC-O. The time concentrated on was from 15 to 33 min for GC-O, which was different to the time concentrated on for GC-MS. The amounts of both volatile compounds and odorants in pine were more than in fir. After extraction, the amounts and intensities of some odorants decreased, while some remained. However, the extraction process resulted in benzene residue and led to increased benzene odor.

CeO₂ was found to promote ester forming alcoholysis reactions of tertiary amides. The present catalytic system was operationally simple, recyclable and it does not require additives. The esterification process displayed a wide substrate scope (>45 examples; up to 93 % isolated yield). Results of a d. functional theory (DFT) study combined with in-situ FT-IR observations indicated that the process proceeded through rate limiting addition of a CeO₂ lattice oxygen to the carbonyl group of the adsorbed acetamide species with energy barrier of 17.0 kcal/mol. This value matched well with exptl. value (17.9 kcal/mol) obtained from anal. of the Arrhenius plot. Further studies by in-situ FT-IR and temperature programmed desorption using probe mols. demonstrated that both acidic and basic properties were important and consequently, CeO₂ showed the best performance for the C-N bond cleavage reaction.

And the article was included in Solid State Nuclear Magnetic Resonance in 2012.Related Products of 5444-75-7 The following contents are mentioned in the article:

In this study, solid-state ¹³C NMR spectroscopy was utilized to characterize and identify the metal-ester coordination in active fourth-generation (phthalate) Ziegler-Natta (ZN) catalysts. It is known that different donors affect the active species in ZN catalysts. However, there is still limited data available of detailed mol. information on how the donors and the active species are interacting. One of the main goals of this work was to get better insight into the interactions of donor and active species. Based on the anisotropy tensor values (δ₁₁, δ₂₂, δ₃₃) from low magic-angle spinning ¹³C NMR spectra in combination with chem. shift anisotropy calculations (δ _aniso and η), both the coordinative metal (Mg/Ti) and the symmetry of this interaction between metal and the internal donor in the active catalyst (MgCl₂/TiCl₄/electron donor) system could be identified.

High pressure viscosity behaviour of tris(2-ethylhexyl) trimellitate up to 150 MPa was written by Lineira del Rio, Jose M.;Guimarey, Maria J. G.;Comunas, Maria J. P.;Fernandez, Josefa. And the article was included in Journal of Chemical Thermodynamics in 2019.COA of Formula: C15H22O2 The following contents are mentioned in the article:

This article presents a study on the viscous behavior at high pressure of a synthetic oil, tris(2-ethylhexyl) trimellitate. This fluid is being recommended as potential industrial reference material for high viscosity-high pressure measurements. Here we report new exptl. viscosity values for TOTM at temperatures from 278.15 K to 373.15 K and at pressures to 150 MPa with a maximum viscosity of 2570 mPa s. The measurements have been performed using a high pressure falling-body apparatus and a Couette rotational viscometer. The exptl. values obtained in this work are included in the database of a multinational project used recently to develop a reference correlation for TOTM. The universal viscosity-pressure coefficient of this fluid has been evaluated and compared with other oils, finding that it is close to the literature values of mineral oils. Moreover, we perform an anal. of the dependency of viscosity on pressure and temperature based on the d. scaling concept. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7COA of Formula: C15H22O2).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
