A process for the production of unsaturated fatty alcohols with improved low-temperature behavior

The invention relates to a method for the production of non-saturated fatty alcohols with improved low-temperature behaviour. In accordance with the invention, primary alcohols of formula (I): R OH, in which R stands for a non-saturated or predominantly non-saturated hydrocarbon radical with 6-22 carbon atoms, are subjected to fractional crystallization. This method makes it possible to obtain products having higher iodine value and lower turbidity point, and is not technically complex.
