Abstract
Procedure for the isomerization of fatty acid esters with isolated double ligatures to the corresponding compounds with conjugated ligatures, using alkaline reaction alcoholates, characterized in that the isomerization is carried out at temperatures from 0ºC to 160ºC in the presence of at least one 0.8% by weight - calculated as potassium methylate and on fatty acid ester - of an alkali-reacting alcoholate of a monovalent alcohol in the presence of strongly polar aprotonic solvents, and the quantitative ratio of solvents to fatty acid esters it is at least 0.5: 1.
