A comprehensive review of recent existing methods of epoxidation of vegetable oils, unsaturated
fatty acids and alkyl esters of unsaturated fatty acids has been presented. The importance of
epoxidized vegetable oils and their applications in the production of polyols and polyurethanes was
discussed. Interests of researchers have been mainly focused on the development of advantageous
technological parameters of vegetable oils epoxidation. The epoxidations with peracetic acid or performic
acid generated in situ were mainly performed in the presence of strongly acidic catalysts. The
influence of process variables such as temperature, stirring speed, the molar ratio of carboxylic acid
and hydrogen peroxide to the amount of ethylenic unsaturation, amount of catalyst and reaction time
on the course of epoxidation has been investigated.
