The chemical conversion of refined rapeseed oil with methanol produces a rapeseed methyl ester in the form of a clear liquid, not thick, flammable, not soluble in water that emits a faint odor. It is used as a substitute for diesel (Biodiesel) but the rapeseed methyl ester is also used as a solvent in specialized industries (glues). The main components of rapeseed methyl ester are oleic acid (55-65%), linoleic (18-25%), linolenic (5-11%) and palmitic (5-8%). Other fatty acids form <1% of the product.
