Abstract
The process for the synthesis of an alkylpolyglucoside having the formula (I): EQU H--(G).sub.n --O--R-- (I) wherein PA1 R is linear or branched, saturated or unsaturated C.sub.8 -C.sub.20 alkyl; PA1 G is a radical resulting from removal of a molecule of water from a monosaccharide; and PA1 n is an integer from 1 to 5; the process entailing reacting an alcohol with a monosaccharide or a compound capable of generating a monosaccharide in in situ, wherein the reaction is carried out in the presence of a catalyst consisting of one or more sterically hindered polyalkylarylsulfonic acids.
