Abstract
PURPOSE: To obtain, to industrial advantage, the titled high-grade cyanoethylcellulose providing mixed paper having excellent heat resistance, etc., by reacting cellulose with acrylonitrile in the presence of a specified amount of a caustic alkali catalyst and water.
CONSTITUTION: To a cellulosic fiber is added an aqueous solution of a caustic alkali in an amount providing 0.01W0.1mol caustic alkali, e.g., caustic soda, and 0.5W3mol water per hydroxyl group contained in the cellulose. The resulting mixture is treated, for example, in a kneader. Next, about 3W8 times, by mol, the hydroxyl groups contained in the cellulose, of acrylonitrile is added, and the mixture is reacted under agitation at a reaction temperature of 30W70°C to obtain cyanoethylcellulose having a degree of cyanoethyl group substitution of below 1.5, a fiber form, good maceration in water and good paper making ability.
