PCT No. PCT/EP96/00752 Sec. 371 Date Nov. 20, 1997 Sec. 102(e) Date Nov. 20, 1997 PCT Filed Feb. 23, 1996 PCT Pub. No. WO96/37501 PCT Pub. Date Nov. 28, 1996A process for producing alkyl oligoglucosides having a high degree of polymerization involving: (a) providing a fatty alcohol; (b) providing a glucose component; (c) mixing the fatty alcohol and glucose component; (d) acetylizing the reaction mixture by adding an acid catalyst to the mixture; (e) continuously distilling off water from the reaction mixture during acetylization; (f) neutralizing the acid catalyst upon completion of acetylization; (g) removing unreacted fatty alcohol from the reaction mixture; (h) post-polymerizing the reaction mixture to form a final alkyl oligoglucoside product; and (i) neutralizing any remaining acid catalyst and removing any unreacted fatty alcohol from the reaction mixture.
