paper-and-pulp industry. SUBSTANCE: ground cellulose is heated with N- methylmorpholine monohydrate at stirring until of monohydrate is melted, after which organic protonic compound (formamide) is added at stirring (200 to 1200 rpm) for 10 to 60 min in amount 10-40% of the weight of N-methylmorpholine monohydrate heated to 75-95 C until cellulose is completely dissolved. EFFECT: increased concentration of cellulose, homogeneity, and improved filtration characteristics due to relatively low viscosity. 2 cl, 3 tbl, 10 ex
