Enhanced catalyst activity of wo3 using polypyrrole as support for acidic esterification of glycerol with acetic acid... The activity of the catalysts was tested in glycerol esterification with acetic acid, and it found that WO3-Ppy-20 (nanocomposite with 20% WO3 loaded) showed the maximum catalyst activity with 98% and selectivity of 70% to triacetin at 110°C with a reaction duration of 10 h and also recorded the highest selectivity (75%) for acetylation of glycerol to monoacetin with about 59% conversion only....
Continuous synthesis of a green fuel additive mixture with highest quantities of solketalacetin and solketal and lowest amount of diacetin from biodiesel-derived glycerol... At first, glycerol was reacted with acetic acid in a continuous system to synthesize monoacetin using a small plug flow reactor and central composite design to optimize the variables related to monoacetin synthesis....
Synthesis of solketalacetin as a green fuel additive via ketalization of monoacetin with acetone using silica benzyl sulfonic acid as catalystSilica benzyl sulfonic acid (SBSA) was prepared as a catalyst for reacting monoacetin with acetone to synthesize solketalacetin as a green fuel additive....
Optimization of solketalacetin synthesis as a greenfuel additive from ketalization of monoacetin with acetone... Monoacetinwas synthesized by reacting glycerol with acetic acid, and then solketalacetinwas produced from the reaction of monoacetin with acetone using PurolitePD 206 as a catalyst....
