| titleOfInvention | Method of cellulose azilonitrate obtaining |
| abstract | FIELD: pulp industry. n SUBSTANCE: invention relates to preparation process of cellulose derivatives, namely cellulose azidonitrate. Preparation process of cellulose azidonitrate comprises reacting cellulose chloronitrate with sodium azide in molar ratio of 1:3 with stirring in aprotic polar solvent at temperature of 40–70 °C in 30–60 minutes, precipitation of obtained product, its filtration, washing and drying. Dimethylsulfoxide, dimethylformamide is used as solvent. n EFFECT: invention makes it possible to considerably shorten process duratio for cellulose azidonitrate obtaining. n 3 cl, 2 dwg, 2 tbl |
