METHOD FOR PRODUCING LEVOGLUCOSAN

摘要

Invention relates to processing cellulose-containing raw material and namely obtaining levoglucosan from wood. The raw material is treated by 10-40% sulphuric acid, hydrolysed with superheated steam at a temperature of 110-1400C and a pressure of 0.2-0.5 MPa. Then the product obtained is washed with demineralised water till pH 3.5. This method yields up to 30.9% of cellulose.
