The present invention relates to a process for the skeletal isomerization of unsaturated linear fatty acids to branched fatty acids which comprises contacting said unsaturated linear fatty acids with at least one large pore zeolite catalyst wherein said at least one zeolite catalyst comprises a material having a three dime nsional channel structure having a pore diameter of at least 6.0 .ANG.. In another embodiment, the invention relates to a process for the skeletal isomerization and hydrogenation of unsaturated linear fatty acids to saturated branched fatty acids which comprises contacting said unsaturated linear fatty acids with at least one metal-zeolite catalyst.
La présente invention concerne un procédé d'isomérisation squelettique d'acides gras linéaires non saturés en acides gras ramifiés, consistant à mettre en contact lesdits acides gras linéaires non saturés avec au moins un catalyseur de zéolite poreux de grande dimension. Ledit catalyseur de zéolite comprend un matériau présentant une structure de canal à trois dimensions avec un diamètre de pore d'au moins 6,0 .ANG.. Dans un autre mode de réalisation, l'invention concerne un procédé d'isomérisation squelettique et d'hydrogénation d'acides gras linéaires non saturés en acides gras ramifiés saturés, consistant à mettre en contact lesdits acides gras linéaires non saturés avec au moins un catalyseur de zéolite métallique.
