METHOD OF SEPARATION OF FATTY ALCOHOLS FROM SOLUTIONS COMPRISING ALKYL POLYGLYCOSIDES AND FATTY ALCOHOLS BY DISTILLATION

摘要

Fatty alcohols are separated from a solution containing alkyl polyglycosides (APGs) and alcohols, wherein the alcohols and the alkyl groups of the APGs contain 10-18 C atoms and wherein the mean degree of polymerization of the (APGs) is 1.05-1.4 by distilling said solution at 160 DEG -200 DEG C. under a pressure of 0.1-20 hPa in a thin layer evaporator having a Reynolds number of 30-18,000.
