Abstract
Esters of olefinically unsaturated carboxylic acids containing 10-20 carbon atoms are made by reacting the acid with an alcohol containing up to 10 carbon atoms in the presence of an inorganic hydrogen sulphate, which has no polymerizing activity and which is insoluble in the reaction mixture, at a temperature of 100-180 DEG C., the reaction water being removed from the mixture in the vapour of the unconverted alcohol. If necessary the reaction is carried out under reduced pressure. Aliphatic, cycloaliphatic or aromatic alcohols may be used. Suitably the alcohol is added to a mixture of acid and catalyst and heated to 140-160 DEG C. Preferably, the catalyst is potassium hydrogen sulphate. Examples describe the preparation of methyl oleate, ethyl oleate, isopropyl oleate, methyl undecylate and isononyl oleate. Suitable apparatus is described.
