Abstract

Abstract Translated from German Oberflächenaktive Alkylglucoside werden in einem zweistufigen Verfahren aus Stärke oder Stärkeabbauprodukten wie Polyglucose- oder Glucose-Sirup hergestellt, wobei in der ersten Stufe die Umsetzung mit einem kurzkettigen Alkohol, insbesondere Butanol, und in der zweiten Stufe die Umacetalisierung mit dem längerkettigen C8- bis C22-, insbesondere C12- bis C18-Alkohol erfolgt, wobei Fettalkohole natürlichen Ursprungs bevorzugt verwendet werden. Surface-active alkyl glucosides are produced in a two-stage process from starch or starch degradation products such as polyglucose or glucose syrup, in the first stage the reaction with a short-chain alcohol, in particular butanol, and in the second stage the transacetalization with the longer-chain C8 to C22 , in particular C12 to C18 alcohol takes place, fatty alcohols of natural origin are preferably used.
