Application 115/DEL/2001 published 2006-05-12, filed 2001-01-31
The invention relates to a process for preparation of cellulose fractions. In the process fractionation of cellulose into different molecular weight fractions is carried out by dissolving cellulose in lithium chloride/N, N-dimethyl acetamide solvent system and using water as a non solvent for regeneration of different molecular weight fractions and the defferent molecular weight fractions of cellulose.
