Abstract

1,250,204. Saccharose esters. R. ISMAIL. 11 Dec., 1968 [11 Dec., 1967], No. 58978/68. Heading C2C. Saccharose fatty acid esters are prepared by feeding continuously (1) a solution of saccharose with 0.05-2% by weight'of an alkaline catalyst in a polar solvent and (2) a solution prepared separately of a fatty acid ester derived from a C 12-22 straight chain saturated or unsaturated fatty acid and a C 1-6 aliphatic or cycloaliphatic, mono- or poly-hydric alcohol in an aliphatic or aromatic hydrocarbon or chlorohydrocarbon of boiling point 70-250‹ C. into a reaction cascade which consists of at least three reaction zones connected one after the other in which the reagents are intensively mixed at a temperature 40-150‹ C. and the alcohol liberated in the ester interchange is distilled off under reduced pressure and the mixture issuing from the last reaction zone after a mean residence time of 1-15 hours is sent to a settling vessel, divided in two phases and the polar solvent phase containing the saccharose ester is concentrated by evaporation under reduced pressure in a continuously working drier, and the polar solvent which is liberated in the drier is fed back for re-use earlier in the process. The alkaline catalyst is preferably potassium carbonate, the polar solvent dimethyl sulphoxide and the aromatic hydrocarbons may be benzine. In the examples saccharose and potassium carbonate in dimethyl sulphoxide are reacted with 12-hydroxy-stearic methyl ester in benzine to yield a saccharose ester.
