Process for continuous manufacture of alkylglycosides

摘要

Alkylglycosides are manufactured by continuous reaction of monosaccharides with fatty alcohols in the presence of an acid catalyst, comprising continuously adding the monosaccharides, fatty alcohols, and catalysts to a continuous stirred-tank reactor (CSTR). The reaction takes place under steady-state conditions with a conversion of 97%+/-2.5% relative to the monosaccharide used. Water is removed continuously from the CSTR during the reaction, and the reaction mixture is removed from the CSTR in an amount which essentially corresponds to the amount of reactants and catalysts added.
