Abstract:
A process is described in which an unsaturated fat is reacted in a homometathesis reaction in the presence of at least one non-aqueous ionic liquid to produce both an olefinic fraction and a composition of monoalcohol diesters or diacids.Particular application to a mixture of esters of an oleic sunflower seed oil or an oleic rapeseed oil, the process producing both an olefinic fraction and a composition of monoalcohol diesters or diacids wherein, in general, more than half of its chains is constituted by unsaturated C18 chains.
