Abstract
Light-colored alkyl or alkenyl oligoglucosides are obtained by a process in which glucose or aqueous starch degradation products are reacted with fatty alcohols in the presence of acidic catalysts which are obtained by partial sulfation of C.sub.4-22 fatty alcohols.
Claims2
A process for preparing an alkyl polyglucoside which comprises reacting glucose with a first C.sub.8-22 fatty alcohol in the presence of an acidic catalyst wherein said catalyst is obtained by partial sulfation with sulfur trioxide of a second fatty alcohol of the formula (I)
- R.sup.1 --OH (I)
- wherein R.sup.1 is an alkyl or alkenyl radical having from 8 to 22 carbon atoms, wherein the degree of sulfation is from 10 to 30% of the theoretical value and the amount of the catalyst is from about 0.1 to about 5% by weight of glucose.
