    摘要: The invention relates to a process for the preparation of fatty acid partial esters of polyols, the fatty acid partial esters thus obtainable, and their use. The fatty acid partial esters (I) of polyols having at least 4 C atoms, at least one primary and at least one secondary alcohol group of the starting polyols are obtained in a process, where in a first process step the polyols are reacted with a fatty acid or a fatty acid derivative to give a fatty acid partial ester (II) and in a second process step the fatty acid partial esters (II) obtained are subjected to a selective enzymatic cleavage of primary ester groups.

    摘要: An organic phase which comprises a water-insoluble material to be encapsulated, a capsule-forming or matrix-forming monomer or prepolymer and, should this be desirable, a solvent, is dispersed in droplet form in an aqueous phase. The capsule-forming or matrix-forming monomer or prepolymer forms a sheath around the material to be encapsulated. As a capsule-forming or matrix-forming monomer, an organosilicon compound of the general formula ##STR1## is used, wherein R.sup.1 is a linear or branched, saturated or unsaturated, n-functional hydrocarbon moiety, which may be interrupted by groups containing oxygen, nitrogen or sulfur; R.sup.2 and R.sup.3 are the same or different and represent a hydrocarbon moiety with 1 to 6 carbon atoms or X; X is a hydroxyl group or a hydrolyzable group and n is a whole number greater than or equal to 1, with the proviso that, when n=1, R.sup.1 has at least 12 carbon atoms and R.sup.2 and R.sup.3 represent X or a prepolymer hereof. The method can be carried out easily and requires only one compound to form the capsules or micromatrix bodies. In the implementation of the method, no foam occurs and the method results in end products with an acceptable shelf life.
