Abstract

 The esterification reaction between Bis (4-hydroxy phenyl) propane and unconjugated fatty acids has been catalysed by the presence of one of the oxides of group it elements, viz: Mgo, Cao, Sro and Dao. The reaction was followed by determining the acidity of samples withdrawn periodically from the reaction mixture. The working conditions of applying the alkaline earth metal oxides as catalysts, have been discussed. The optimum conditions for completion of the reaction at the minimum tine are given. 
Previous work on the effect of Cao on the esterification process draw the attention to investigate the rest of G it elements.
