Abstract

Izgudrojums attiecas uz celulozi saturošu izejvielu apstrādi, proti, levoglikozāna ieguvi no koksnes izejvielām. Izejviela vispirms tiek apstrādāta ar 10-40% sērskābi, hidrolizēta ar pārkarsētu ūdens tvaiku 110-1400C temperatūrā un ar spiedienu 0,2-0,5 MPa. Pēc tam iegūto produktu mazgā ar demineralizētu ūdeni līdz pH 3,5. Minētā metode ļauj iegūt levoglikozānu līdz 30,9% no celulozes daudzuma.
