Abstract

A process for preparing glucose from a cellulose material, in which a cellulose-comprising starting material is provided and treated with a liquid treatment medium comprising an ionic liquid whose anions are selected from among polyatomic anions and the cellulose-comprising material which has been treated with the ionic liquid is subjected to an enzymatic hydrolysis, is described.
