Abstract:
PCT No. PCT/EP92/02343 Sec. 371 Date Apr. 21, 1994 Sec. 102(e) Date Apr. 21, 1994 PCT Filed Oct. 12, 1992 PCT Pub. No. WO93/08203 PCT Pub. Date Apr. 29, 1993Light-colored alkyl oligoglycoside pastes can be obtained by a process in which a) glycose is reacted with fatty alcohols in the presence of acidic catalysts at elevated temperature to a residual content of glycose of less than 0.1% by weight, based on the starting quantity of glycose, b) water of reaction released is continuously removed from the equilibrium, c) the reaction products are neutralized with a base, the molar ratio of hydrogen ions in the reaction mixture to added base being from 1:1 to 1:1.5, d) unreacted fatty alcohols is separated by distillation, e) the residue is subsequently processed by addition of water to a paste having a solids content of 30 to 70% by weight, based on the paste, the paste is alkalized and, optionally, bleached by methods known per se.
