Abstract
Изобретение относится к химии целлюлозы и ее производных, а именно к способу получения активированной целлюлозы, и может быть использован в качестве сырья для сополимеризации целлюлозы с другими мономерами. Активацию целлюлозы осуществляют следующим образом: измельченную целлюлозу 1×1 см пропитывают водным раствором персульфата калия, а потом осуществляют сушку целлюлозы при температуре 100-105°С в течение 60-90 мин. При этом максимально повышается хрупкость макромолекулярной структуры целлюлозы, и при помоле в течение 8-14 мин разрушаются макромолекулярные и волокнистые структуры, и это приводит к получению сыпучего порошка целлюлозы с увеличением реакционной способности, содержания фракции целлюлозы с размерами частицы 200 мкм и ниже составляет до 94,2 вес.%. Активированный порошок целлюлозы можно использовать при процессе сополимеризации с ненасыщенными мономерами, а так же в качестве загустителя и сырья для лакокрасочной, текстильной и вискозной промышленности. Молекулярный вес активированной целлюлозы составляет 250-273.The invention relates to the chemistry of cellulose and its derivatives, in particular to a method for producing activated cellulose, and can be used as a raw material for the copolymerization of cellulose with other monomers. The activation of cellulose is carried out as follows: 1 × 1 cm pulverized cellulose is impregnated with an aqueous solution of potassium persulfate, and then the cellulose is dried at a temperature of 100-105 ° C for 60-90 minutes. This maximizes the fragility of the macromolecular structure of cellulose, and when grinding for 8-14 minutes, macromolecular and fibrous structures are destroyed, and this results in a free-flowing cellulose powder with an increase in reactivity; , 2 wt.%. Activated cellulose powder can be used in the process of copolymerization with unsaturated monomers, as well as as a thickener and raw material for paint and varnish, textile and viscose industries. The molecular weight of activated cellulose is 250-273.
