Biofuel containing levoglucosone and its production process from cellulose or starch using as a solvent a mixture of an ionic liquid and an alkyl alcohol

摘要

The product Biofuel is presented as a motor fuel consisting of levoglucosone pure or mixed with ethanol and or hydrocarbons.;Its production process from cellulose or starch uses in the first step, as a solvent and catalyst, a mixture of an alkyl alcohol, the ionic liquid N-alkyl imidazole hydrochloride and a small quantity of 37% concentrated hydrochloric acid.;In the second step, levoglucosone is extracted with butanol. As butanol also extracts some N-alkyl imidazole, this is washed out by extraction with hydrochloric acid.;Levoglucosone was identified by elemental analysis, NMR C13 and H and GC-MS.
