Method of removing extractive substances when producing cellulose, cellulose obtained using said method and use thereof |
abstract |
FIELD: chemistry. n SUBSTANCE: method involves preparing acid liquor by adding a soap-oil mixture to pulping liquor and heating the cellulose material in the presence of the acid liquor. Resin-free cellulose is obtained when extractive substances are removed in the presence of the soap-oil mixture. n EFFECT: low power consumption when processing wastes for recycling, low concentration of resins and minimising precipitation thereof, low consumption of sulphuric acid. n 19 cl, 1 tbl, 2 ex |
