Key words: rapeseed oil hydrolysis, oleic acid oxidation, azelaic acid esterification, heterogeneous catalyst, supercritical conditions, 2-ethylhexyl ether
Three chemical stages of azelaic acid 2-ethylhexyl ester synthesis based on rapeseed oil
were studied: hydrolysis of the initial oil, oxidation of oleic acid in the presence of
palladium-containing heterogeneous catalyst, and esterification of azelaic acid. It is
demonstrated that reactions hydrolysis and esterification can be efficiently carried out
under supercritical conditions (523—653 K and 22.5—30 MPa).
