Patent

CA 2174426

This invention relates to novel urea fractionation process for purification of e.g. fatty acids and derivatives thereof. The process is characterised in that the urea complexation takes place under heterogenous conditions using a solvent or solvent mixture wherein the fatty acids (or derivatives) are only slighty soluble. thus forming a two-phase system. This allows for continued regeneration of urea and simple procedures for product isolation.

Nouveau procédé de fractionnement d'urée dans le but d'épurer, par exemple, les acides gras et leurs dérivés. Le procédé est caractérisé en ce que la complexation de l'urée s'effectue dans des conditions hétérogènes au moyen d'un solvant ou mélange de solvants dans lequel les acides gras (ou les dérivés) ne sont que faiblement solubles, ce qui forme un système à deux phases. Par conséquent, on obtient une régénération continue de l'urée et des procédures simples d'isolement de produits.
