Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...
