    Abstract: This invention relates to a process for the selective hydrogenation of vegetable oils. In particular the invention relates to a process for the hydrogenation of vegetable oils which is capable of selectively converting polyunsaturated fatty acids into mono-unsaturated fatty acids and products obtained therefrom. The vegetable oils obtained from the process according to the invention have in particular a high mono-unsaturated fatty acids content and are particularly suitable for use as raw materials for the synthesis of chemical intermediates.

    Abstract: This invention relates to the use of a composition of aliphatic esters having the following general formula: R1-O- C(0)-R4-C(O)-[-O-R2-O-C(O)-R5-C(O)-]m-O-R3 in which: R1 is selected from one or more of the groups consisting of H, linear and branched saturated and unsaturated alkyl residues of the C1-C24 type, and polyol residues esterified with C1-C24 monocarboxylic acids; R2 comprises -CH2-C(CH3)2-CH2- and C2-C8 alkylene groups, and comprises at least 50% in moles of the said -CH2-C(CH3)2-CH2- groups; R3 is selected from one or more of the groups consisting of H, linear and branched saturated and unsaturated alkyl residues of the C1-C24 type, and polyol residues esterified with C1-C24 monocarboxylic acids; R4 and R5 comprise one or more C2-C22 alkylenes and comprise at least 50% in moles of C7 alkylenes; m lies between 1 and 20, as plasticizers for polymer compositions. These esters are particularly suitable for use as plasticisers for various types of polymers such as for example vinyl polymers of the polyvinyl chloride (PVC) type, thermoplastic elastomers, and hydroxy acid polyesters, for example polyesters of lactic acid.
