Abstract
PURPOSE: To obtain an alkali chitin, completely soluble in ice water, which is under consideration as a replacement for the biological membrane, by boiling chitin under pressure at a high temperature with addition of water, and then treating it with an aqueous alkali solution.
CONSTITUTION: Chitin is mixed with water and the mixture is boiled at 0.1W 5kg/cm2, preferably 1W25kg/cm2, at 103W160°C, preferably 110W140°C. The obtained gruel-like substance is filtered, and the resulting bean curd refuse-like chitin powder is loosened and impregnated with an alkali under pressure after addition of an aqueous alkali solution at 15°C. It is then frozen, thawed and impregnated again with the alkali under pressure, to obtain an alkali chitin, which is homogeneously soluble in ice water. 0.1W1,000pts.wt., preferably 1W100pts.wt. of water is added to 1pts.wt. of chitin, and the period of time for the treatment is preferably 30minW10hr.
