Xiao, Mengshi published the artcileSynthesis of Biodiesel from Waste Cooking Oil by One-step Esterification and Its Structural Characterization, COA of Formula: C23H46O2, the main research area is waste cooking oil biodiesel esterification.
The preparation of biodiesel as an alternative to petroleum-based fuels can expand the research and development of renewable energy, and is conducive to environmental protection. In this study, waste cooking oil (WCO) was used as raw material, and then pretreated, and then esterified with methanol under the action of sodium hydroxide catalyst to transformed into fatty acid Me ester (FAME) to prepare biodiesel. The reaction conditions were optimized by a three factorial Box-Behnken design through response surface methodol., when the reaction temperature was 70.1°C, the catalyst concentration was 1.013% and the molar ratio of methanol to oil was 6.5:1, the maximum FAME was up to 99.342%. Finally, the conversion of the triglyceride to the Me ester was confirmed by NMR (1H and 13C), and no unsaturation was present in the Me ester. The chem. composition of biodiesel was determined by GC-MS anal. There are mainly 11 FAME ranging from C16 to C24. The potential of WCO to prepare biodiesel was obtained.
Waste and Biomass Valorization published new progress about Acid number. 929-77-1 belongs to class esters-buliding-blocks, name is Methyl docosanoate, and the molecular formula is C23H46O2, COA of Formula: C23H46O2.
