FIELD: chemistry.

SUBSTANCE: invention relates to a method of purifying and processing natural oily glycerides, which includes providing (a) raw material which includes natural oily glycerides, and (b) low-molecular weight olefins; cross-metathesis of natural oily glycerides with the low-molecular weight olefins in a metathesis reactor in the presence of a metathesis catalyst to form a metathesis reaction product, which includes olefins and esters; separating the olefins in the metathesis reaction product from the esters in the metathesis reaction product to obtain a separated olefin stream; and recycling the separated olefin stream into the metathesis reactor. The natural oily raw material can be converted into useful chemicals, e.g., wax, plastic, cosmetic agents, biofuel etc., with any number of different exchange reactions.

EFFECT: improved method.
