Present studies concentrated on a comparison of catalytic performance of number of solid acid catalysts in transesterifiaction of triglycerides with methanol. Reaction was studied for triacetin, the short triglyceride, and for castor oil consisting of vegetable fatty acid esters under mild reaction conditions. The affinity of catalysts was also evaluated from the drop of catalyst activity induced by glycerol added to the reaction mixture or by pre-treatment of catalyst with triacetin. The strength of acid sites seems to be decisive factor for the activity and, in particular, for deactivation due to polar reagents adsorption. Greater affinity toward glycerol and higher strength of acid sites, deactivation of catalysts would be easier.
