Biocell - Biofuel containing mixtures of isomers of alkyl glucose or their hydrogenation product and its production process from cellulose or starch using as a solvent a mixture of an alkyl alcohol, an ionic liquid immiscible with water and hydrochloric acid

摘要

Biofuel containing mixtures of isomers of alkyl glucose in the linear form, pyran or furan forms, as well as their hydrogenation products.;Methyl cellulose may contain one to four methyl groups substituting hydrogen atoms in the original hydroxyl groups contained in glucose, the monomer of cellulose.;Its production process from cellulose or starch uses in the first step, as a solvent, a mixture of alkyl alcohol, an ionic liquid immiscible with water like trioctyl amine, tributylamine or their mixtures as hydrochlorides and hydrochloric acid.;In the second step, after the methanolysis of cellulose and the methylation of glucose catalysed by the acid, the methyl glucose molecules are separated by extraction with water.;Water is evaporated and the biofuel, alkyl cellulose, is obtained and identified by elemental analysis, NMR and FT-IR.;As an option, alkyl glucose is hydrogenated and converted in dimethyl tetrahydrofuran, which is a gasoline component.
