Аннотация:The current work has shown the potentials forthe aerobic oxidation of fatty acid methyl ester (FAME) of vegetable oils in the production of polyvinylchloride (PVC)plasticizers with the exclusion of other reagents. The reaction mixtures contain epoxidized derivatives of FAME, and esters, with the quantity of the ester groups being higherthan in the initial raw material. It was established that the increase in the additional ester groups resulting from the “aerobic” Baeyer-Villiger (BV) reaction has a significantly positive influence on the plasticizing ability of the oxidized FAME mixtures for PVC when compared to the formationof epoxide compounds. The development of the technology for the production of PVC plasticizers proposed in this investigation provides an pportunity for resolving some of the environmental issues normally associated with the usem of phthalate-based plasticizers.
