- W2618738051 abstract "This work describes production of buthyl esters of fatty acids by the transesterification of rapeseed oil with alkali homogenous catalyst. At the first part, the transesterification and reaction components for biodiesel production are described. The reaction was terminated by the neutralization of catalyst, which proceeded by strong mineral acids such as H2SO4, H3PO4 and HCl. The aim of this work was to investigate and optimise neutralization conditions. It was found that hydrochlorid acid is the best acid for neutralization. The colloidal mixture, which is unable to filtrate off, is not formed by this acid. The pH was necessary to be measured during the addition of hydrochlorid acid to the reaction. When pH was under 3, pouring of acid had to be stopped. Hydrochlorid acid has also a catalytic activity; the excess of acid causes a reverse reaction (glycerides are formed from ester and butanol)." @default.
