A process is described in which an unsaturated fat is reacted with ethylene in a metathesis reaction in the presence of at least one non-aqueous ionic liquid to produce both an olefinic fraction and a composition of monoalcohol or polyol esters. Particular application to an oleic sunflower seed oil, an oleic rapeseed oil or to a mixture of monoalcohol esters of said oils, the process producing both an olefinic fraction and a monoalcohol or glycerol esters composition generally having more than half of its chains constituted by unsaturated C10 chains.
A process for producing both an olefinic fraction and an ester composition, characterized in that it comprises bringing at least one unsaturated fat comprising at least one ester formed between at least one monocarboxylic acid comprising at least one ethylenically unsaturated bond and at least one aliphatic monoalcohol or at least one aliphatic polyol into contact, under metathesis conditions, with an excess of ethylene in the presence of a catalyst and in the presence of at least one non-aqueous ionic liquid.
