METHOD FOR PRODUCING GLUCOSE HYDROLYSATE OF BIRCH WOOD Russian patent published in 2016 - IPC C13K1/02 

FIELD: technological processes.

SUBSTANCE: method for producing glucose hydrolysate of birch wood comprises pretreatment of birch shavings with aqueous solution containing 30 wt% of acetic acid and 4-5 wt% of hydrogen peroxide, while heating. It is followed by hydrolyzing with concentrated sulfuric acid, diluting with water and inversion at 100 °C for 1 hour with further separation of an end product. Wood shavings are being treated at atmospheric pressure, temperature of 90-100 °C, liquid module 5-15 for 3 hours. Acid hydrolysis of the produced cellulose is being carried out at temperature of 25-50 °C, liquid module 0.8-1.4 for 20-60 minutes with further dilution with water to fluid module 8.

EFFECT: invention provides reduced consumption of reagents and energy resources and simplified method.
