Methods for sequential saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems, with alkali in a polyether alcohol solvent to yield soaps with conjugated double bond systems are disclosed. The novel properties of the polyether alcohols allow the removal of water added with the alkali by boiling. The preferred embodiment uses a vegetable oil rich in linoleic acid such as sunflower or safflower oil, potassium hydroxide, phosphoric acid to neutralize the soaps. The reaction forms equal quantities of 9Z,11E-octadecadienoic acid and 10E,12Z- octadecadienoic acids.
La présente invention concerne des procédés de saponification séquentielle et d'isomérisation quantitative d'huiles glycérides contenant des systèmes de liaisons doubles interrompues, avec un alcali dans des solvants de polyéther alcool afin d'obtenir des savons comportant des systèmes de liaisons doubles conjuguées. Les nouvelles propriétés des polyéthers alcools permettent d'éliminer l'eau ajoutée à l'alcali par cuisson. Dans un mode de réalisation préféré, on utilise une huile végétale riche en acide linoléique telle que l'huile de tournesol ou de carthame, de l'hydroxyde de potassium, de l'acide phosphorique pour neutraliser les savons. La réaction produit de l'acide 9Z,11E-octadécadiénoïque et des acides 10E,12Z-octadécadiénoïques en quantités égales.
