  • Process for making alkylpolyglycosides
    Patent number: 6077945
    Abstract: A novel process for making an alkylpolyglycoside comprises reacting a monosaccharide with an alcohol in the presence of a binary sulfate catalyst under heat. The particular binary sulfate catalyst is a mixture of H.sub.2 SO.sub.4 and inorganic base at a normal ratio of about 0.7:1 to 1.1:1 of H.sub.2 SO.sub.4 to inorganic base. Also the alkylpolyglycoside product from the reaction mixture can be isolated so that the alkylpolyglycoside process contains less than 5 weight percent free alcohol, and further separated into a white, free flowing powder of high DP (degree of polymerization) alkylpolyglycoside and a low DP alkylpolyglycoside paste.
