IMPROVED METHOD FOR EPOXIDATION OF FATTY ACIDS, ESTERS THEREOF AND MIXTURES THEREOF Russian patent published in 2016 - IPC C07D301/19 C07D303/40 B01J23/28 B01J21/04 B01J27/14 C11C3/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to an improved method for epoxidation of mono-and polyene fatty acids, esters thereof and mixtures thereof, according to which a solid catalyst is used, which is a group VIB metal oxide applied on a support. Said support includes silicon dioxide, aluminium oxide and mixtures thereof, and a group VA promoter. Content of group VIB metal oxide in the catalyst is 5-20 wt% of weight of support. Mono- and polyene fatty acids, esters thereof or mixtures thereof are brought into contact with said catalyst for a period of time ranging from 0.5 to 6 hours at temperature ranging from 40 to 120 °C followed by extraction of epoxy product from reaction mass to produce mono- and polyepoxy-functionalised fatty acids, esters and mixtures thereof. Amount of by-products in obtained epoxy product is less than 1 %.

EFFECT: disclosed method enables to achieve virtually complete conversion of initial raw material and high selectivity on epoxides and allows reuse of catalyst.
