THE INFLUENCE OF ACYL AND ALCOHOL MOIETIES OF CARBOXYLATE ESTERS ON RAPESEED OIL CHEMICAL INTERESTERIFICATION
Published: 29 Jul 2017
Abstract: An alternative method for the synthesis of biodiesel fuel (FAAE) from rapeseed oil that prevents formation of glycerol has been proposed. In interesterification reaction of rapeseed oil with carboxylate esters (methyl formate, methyl acetate, ethyl acetate, propyl acetate, isopropyl acetate, tert-butyl acetate, methyl propionate, methyl butyrate and methyl isobutyrate) in presence of potassium t-butoxide/t-butanol catalytic system FAAE and triacylglycerols are formed. Triacylglycerols can be considered as valuable additives for biodiesel that do not need to be removed from the reaction mixture. The prolongation of unbranched alkyl group in alcohol moiety reduced the carboxylate ester reactivity while in acyl moiety – practically did not affect it.
