US Patent:

52666905, Nov 30, 1993

Filed:

Dec 19, 1991

Appl. No.:

7/810588

Inventors:

Patrick M. McCurry - Lansdale PA
Robert S. McDaniel - Chalfont PA
William G. Kozak - Hatfield PA
Allen D. Urfer - Lansdale PA
Gail Howell - Fort Mill SC

Assignee:

Henkel Corporation - Ambler PA

International Classification:

C07H 106
C07H 1504
C07H 1500
C07G 300
C08B 3700

US Classification:

536 186

Abstract:

A process for preparing high detergency or surfactant alkyl polyglycoside compositions and a purified alkyl monoglycoside and to compositions employing the polyglycosides for various end use applications. The process involves removal of a substantial portion of the monoglycoside present in a reaction product mixture containing alkyl polyglycosides resulting from the reaction of an alcohol and saccharide at elevated temperatures in the presence of an acid catalyst. Separation of the monoglycoside from the reaction product mixture may be carried out by molecular distillation.
