Obtaining of Oxycellulose from Cotton Fibers by Action of Various Oxidants
Background. Development of production technologies of materials for various purposes of alternatives to crude oil and natural gas sources of raw material, in particular cellulose.
Objective. To determine the optimal values of technological parameters of cotton fiber oxidation by action of various oxidants – hydrogen peroxide, Oxone, PINO – on quality of oxycellulose.
Methods. Oxidation of mechanically chopped cotton fibers by solution of hydrogen peroxide, Oxone and PINO was performed with air bubbling by the compressor through solution of cellulose in round-bottomed flask immersed in a water bath of the required temperature. The methods of experiment planning and optimization were used to determine the optimum process parameters.
Results. Studied oxidants for oxycellulose of cotton fibers to increase efficiency are in the following order: hydrogen peroxide – Oxone – PINO. The method of full factorial experiment was used to determine the adequate regression equations that describe the process of oxycellulose obtaining by action of Oxone and PINO, and the Gauss-Seidel method was used to determine the optimal values of technological parameters of oxycellulose obtaining. It is shown that oxidation of cotton fibers for optimal values of technological parameters allows getting oxycellulose with the content of carboxyl groups to 3 %.
Conclusions. The obtained oxycellulose can be used in medicine as a component of non-toxic, hemostatic, antimicrobial materials.
