Methods for quantitative conversion of soapstock, lecithin gums, deodorizer distillate and other by-products of vegetable oil refining containing interrupted double bond systems, to products with conjugated double bonds, using a reduced amount of alkali. Less than one mole of alkali per mole of acyl group present is required, thereby greatly reducing the need for added caustic compared with methods using oils, fatty acids and esters as starting materials. The preferred starting materials are soapstocks derived from vegetable oils rich in linoleic acid.
Procédés de transformation quantitative de pâte de neutralisation, de gommes de lécithine, de distillat de désodorisant et d'autres sous-produits de raffinage d'huiles végétales contenant des systèmes de doubles liaisons rompues, en produits à doubles liaisons conjuguées, utilisant une quantité réduite d'alcalis. Ces procédés requièrent moins d'une mole d'alcali par mole de groupe acyle présent, ce qui permet de réduire considérablement les besoins en caustiques ajoutés par comparaison avec des procédés utilisant des huiles, des acides gras et des esters comme matières premières. Les matières premières préférées sont des pâtes de neutralisation dérivées d'huiles végétales riches en acide linoléique.
