Abstract

Способ получения целлюлозы путем варки измельченного древесного сырья в водном растворе перуксусной кислоты, отличающийся тем, что, с целью повышения выхода целлюлозы и уменьшения длительности процесса, варку проводят в присутствии изобутилового спирта при соотношении водного раствора перуксусной кислоты изобутилового спирта соответственно, об.% 50 - 70 : 30 - 50.A method of producing cellulose by cooking crushed wood raw material in an aqueous solution of peracetic acid, characterized in that, in order to increase the yield of cellulose and reduce the duration of the process, cooking is carried out in the presence of isobutyl alcohol at a ratio of an aqueous solution of peracetic acid to isobutyl alcohol, respectively,% vol. 50 - 70:30 - 50.
