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 dimensional channel structure having a pore diameter of at least 6.0 Å. 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 in the presence of an acidic catalyst, wherein said acidic catalyst comprises a mesoporous crystalline phase having pore walls containing primary and secondary crystalline building unit structures.
A branched fatty acid or alkyl ester thereof prepared by isomerizing a feedstock which comprises unsaturated linear fatty acids, alkyl esters of unsaturated fatty acids or mixtures thereof, wherein said process comprises subjecting said feedstock to an isomerization reaction in the presence of an acidic catalyst having a three-dimensional channel pore structure wherein at least one channel structure has a pore size diameter of at least 6 Å.
A branched fatty acid or alkyl ester thereof prepared by isomerizing a feedstock which comprises unsaturated linear fatty acids, alkyl esters of unsaturated fatty acids or mixtures thereof, wherein said process comprises subjecting said feedstock to an isomerization reaction in the presence of an acidic catalyst, wherein said acidic catalyst comprises a mesoporous crystalline phase having pore walls containing primary and secondary crystalline building unit structures.
