One way to take advantage from out-of-specification biodiesel and waste from biodiesel tank bottom drainage is to co-process them in a fluidized catalytic cracking (FCC) unit. The present work deals with the cracking of oleic acid Me ester (OAME) as a biodiesel model, under conditions close to that of FCC process over ZSM-5 and Y zeolites, either in protonated or sodium forms, towards deoxygenated compounds Catalytic fast cracking of OAME pre-adsorbed on the catalyst surface was performed, with a catalyst:OAME mass ratio of 10:1 in a micro-pyrolysis system at 650°C, coupled to a GC/MS for on line anal. of the products. Results show that the cracking of OAME without a catalyst favored the formation of linear alkenes and polyenes. Fast cracking of OAME over HZSM-5 and HY acidic zeolites led to the production of aromatics, due to hydrogen transfer. Cracking over NaY and HY zeolites produced remarkable amounts of ramified saturated hydrocarbons. The formation of alkylated hydrocarbons was not significant over ZSM-5 zeolite probably due to a small pore size of this zeolite. NaY catalyst favored the production of hydrocarbons in the range of kerosene (C8-C12). Low acidic zeolites favored the production of non-aromatic hydrocarbons. Product distribution was affected by catalyst shape selectivity and acidity. These results suggest that residues from the biodiesel chain can be directly co-processed in FCC units to obtain high value hydrocarbons, mainly in the jet fuel and gasoline ranges.Methyl oleate (cas: 112-62-9) were involved in the experimental procedure.

Cahyo Kumoro, Andri;Saeed, Mahmood Taha M. N. published 《Ultrasound-assisted transesterification of tropical goat fat – Palm oil blend for biodiesel synthesis》 in 2022. The article was appeared in 《Energy Conversion and Management: X》. They have made some progress in their research.Quality Control of Methyl oleate The article mentions the following:

The increasing trend of global energy demand has encouraged the development of renewable energies, especially those derived from biomass and agricultural residues. This work aimed to study the effect of catalyst loading, temperature, and methanol-to-oil molar ratio on the yield and the reaction kinetics of ultrasound-assisted transesterification of tropical goat fats for biodiesel synthesis. Prior to trans-esterification, the oil extracted from the tropical goat fat was mixed with an equal volume of tropical palm oil to prevent its solidification tendency. To reduce the free fatty acids content of the mixed oil, it was esterified using a methanol-to-oil molar ratio of 9 employing 1 wt% sulfuric acid as the catalyst at 65 °C and 400 rpm agitation speed for 60 min. Then, the esterified oil was further subjected to an ultrasound-assisted transesterification system with sodium hydroxide catalyst for the reaction kinetics and biodiesel synthesis studies. The biodiesel properties were evaluated by both laboratory tests and BiodieselAnalyzer software, which employs the fatty acid Me ester composition obtained from GC-MS anal. The highest conversion (78.50%) was achieved at 65 °C, 2.5 wt% of NaOH, and 8:1 methanol/oil blend molar ratio for 60 min. The pseudo-first order reaction fitted all the exptl. data very well by giving the R2 values higher than 0.98 and an apparent reaction rate constant of 2.15×10-2 min-1 at the optimum condition. Furthermore, all the examined biodiesel physicochem. properties fulfilled the ASTM D6751 standard suggesting the promising potential of goat fats as the raw material for biodiesel manufactureMethyl oleate (cas: 112-62-9) were involved in the experimental procedure.

The article contains the following contents:

Me oleate, an example of a FAME (fatty acid Me ester), was produced by oleic acid (OA) photoesterification with TiO2 and UVA light. Different parameters were evaluated and optimized: catalyst pretreatment, temperature (25-65°C), catalyst loading (1-30% weight/weightOA) and oleic acid : alc. molar ratio (1 : 3-1 : 55). Response surface quadratic methodol. obtained by central composite rotational design (RSM-CCRD) was used to evaluate the main operational conditions of the photoesterification process. A high conversion of 98% (±0.8) at 55°C, 20% TiO2 (weight/weightOA), and 1(OA) : 55(methanol) molar ratio was achieved. The photoesterification mechanism is furthermore proposed. The Langmuir-Hinshelwood kinetic model considered the forward and backward reaction as first-order fits with the best accuracy (R2 of 0.997). The thermodn. results (ΔG338.15K = -20.75 kJ/mol, ΔH = 13.75 kJ/mol, and ΔS = 0.47 kJ/mol.K) indicate that the operating conditions are important, both to supply the energy requirement of the reaction, but also to increase the miscibility of the reactants.Methyl oleate (cas: 112-62-9) were involved in the experimental procedure.

Reference of Methyl oleate《Cassia auriculata Linn. extracts induce apoptosis and cell cycle arrest of A549 lung cancer cell lines: An in vitro approach》 was published in 2022. The authors were Rajagopal, Anitha;Rajakannu, Subashini, and the article was included in《South African Journal of Botany》. The author mentioned the following in the article:

Cassia auriculata is an ethnobotanically important traditional medicinal plant of tropical Asia and recently, phytochems. and their derivatives have gained scientific attention for their use as agents in cancer treatment and prevention. The aerial parts of Cassia auriculata plant were subjected to successive cold maceration to yield four fractions viz., n-hexane, dichloromethane, Et acetate, and ethanol extract The extracts were fractionated by GC-MS (Gas Chromatog.-Mass Spectrometry) and HPLC (High-Performance Liquid Chromatog.) anal. for their phytochem. content. The chromatog. techniques revealed the presence of mainly the flavonoid compounds like flavone, chrysin, and quercetin. The anti-proliferative properties of ethanolic extract of C. auriculata on A549 human lung cancer cells have been reported. The cancer cell survival rate (MTT 3- [4, 5- dimethythiazol-2-yl] 2, 5-diphenyl tetrazolium bromide) was found to be reduced with lung cancer cells (IC50 26.24 mug/mL) when treated with C. auriculata ethanol extract (CAEE) when compared to the non-cancerous cells L132. The toxicity of the extract on L132 cells was low (IC50 55.78 mug/mL). The mode of cell death induced by CAEE on A549 cells was examined by various fluorescent staining techniques and characteristic nuclear and morphol. changes for apoptosis were evaluated. The expression of caspase 9 activity was documented, which might have triggered cell death through apoptosis by the activation of caspase 9 in the ethanolic fraction treated A549 cells. Cell cycle anal. of treated A549 cells revealed a promising S phase cell cycle arrest. The flavonoid compounds identified in the present study might be responsible for the remarkable anticancer and other activities of the plant. From these findings, the plant C. auriculata can be further exploited to develop promising candidate mols., particularly for lung cancer chemotherapy. And Methyl oleate (cas: 112-62-9) was used in the research process.

The article was appeared in 《Journal of Bioresources and Bioproducts》. They have made some progress in their research.SDS of cas: 112-62-9 The article mentions the following:

Palm fatty acid distillate (PFAD), a byproduct of refining process of crude palm oil can be used as a potential feedstock for biodiesel production However, the application of palm oil-based biodiesel is often hinder by its poor cold flow properties (CFP). Biodiesel fuel with poor CFP may crystallize and result in clogging of fuel lines, filters and injectors that cause engine operability problems. For that, a vacuum distillation method was designed and its feasibility and efficiency in improving the CFP was examined A total of 13.60wt% of total saturated fatty acid Me esters were successfully removed from the PFAD biodiesel, resulting in the improvement of the cloud point (CP), cold filter plugging point (CFPP) and pour point (PP) of PFAD biodiesel from 20°C, 19°C, and 15°C to 13°C, 11°C, and 9°C, resp. It is remarkable that the improved CFPP satisfied the requirements for grade C summer biodiesel for temperate climates in EN 14212 standard Addnl., Sarin (UFAME) empirical correlation was evaluated and it was found to have a good prediction of CFP for PFAD biodiesel, with lower than 2°C deviation.Methyl oleate (cas: 112-62-9) were involved in the experimental procedure.

The article was appeared in 《Proceedings of the Royal Society B: Biological Sciences》. They have made some progress in their research.Related Products of 112-62-9 The article mentions the following:

Parasitic wasps have long been thought to be unable to synthesize fatty acids de novo, but recent 13C-labeling studies have challenged this view. It remained unclear, however, whether the reported biosynthesis rates are of biol. relevance. Here, we show in Nasonia vitripennis that ageing females with partly depleted lipid reserves produce biol. relevant amounts of fatty acids de novo. Females with varying oviposition history (0-48 h) prior to feeding 20% 13C-labeled glucose solution showed 13C-incorporation rates of (mean ± SEM) 30 ± 2%, 50 ±; 2%, 49 ±; 3% and 21 ± 2% in palmitic, stearic, oleic and linoleic acid, resp. The absolute amounts of fatty acids synthesized de novo across treatments corresponded to 28 ± 3 egg lipid equivalent Females incorporated de novo synthesized fatty acids into their eggs, and glucose-fed females laid more eggs than water-fed control females. The number of eggs laid prior to glucose feeding did not correlate with the degree of lipogenesis, but the amounts of de novo synthesized fatty acids correlated with constitutive (not synthesized de novo) fatty acids. Hence, glucose feeding has a twofold effect on the fatty acid status of N. vitripennis females by decelerating the catabolism of existing fat reserves and partially replenishing ebbing fat reserves by lipogenesis. The experimental procedure involved many compounds, such as Methyl oleate (cas: 112-62-9) .

A phytochem. investigation of hexane extract of Rheum ribes L., Polygonaceae, shoots was analyzed by gas chromatog. with flame ionization dection and mass specrometry and revealed seven components including Me hexadecanoate (Me palmitate) (2.4%), (Z)-9-Me octadecenoate (Me oleate) (2.9%), (Z,Z,Z)-9,12,15-Me octadecatrienoate (Me linolenate) (3.5%), 1-octadecanol (4.3%), (Z,Z)-9,12-Me octadecadienoate (Me linoleate) (5.7%), heptacosane (13.5%), and hexadecanoic acid (palmitic acid) (67.7%). The hexane extract was bioassayed for larvicidal and adult topical activity against an insecticide susceptible strain of Aedes aegypti, the yellow fever mosquito. Results demonstrated a 90% mortality against adults at 5μg/mosquito and first instar larvae at 1μg/μl. The major compound hexadecanoic acid showed 20% mortality at 6.25 ppm against adults whereas the compound provided 100% mortality at the highest screening dose of 1000 ppm against 1st instar larvae. The mosquitocidal activity of the analyzed plant material may be related to a specific combination of compounds present in the hexane extract Graphical abstract And Methyl oleate (cas: 112-62-9) was used in the research process.

Tobacco flavors increase the attractiveness of a tobacco brand and ultimately promote addiction. Information about what flavor and how much flavor is in flavor capsules can provide an effective way to regulate tobacco flavor. In this study, 128 flavor chems. were identified and quantified by gas chromatog.-mass spectrometry using libraries and authentic standards Validation of the developed method was performed for interference, detection limits, calibration curves, accuracy, and precision. Menthol was the main ingredient in all capsules, and the carcinogenic pulegone was detected. Detected menthofuran, benzyl alc., geraniol, and eugenol cause toxic or severe irritation, and detected lactones can increase nicotine addiction by inhibiting nicotine metabolism in smokers. Margin of exposures for carcinogenic pulegone and non-carcinogenic menthol were well below safety thresholds, indicating a significant risk of inhalation exposure. It is desirable to prohibit the use of flavor capsules in consideration of human risk. And Methyl oleate (cas: 112-62-9) was used in the research process.
