Title: Preparation of water-soluble alkali chitin
Inventor: NOGUCHI JIYUNZOU
IPC: C08B37/08
Filed: 1979-05-18
Abstract: PURPOSE: To obtain an alkali chitin completely soluble in ice water, by at least one procedure for the penetration of an alkali into a chitin powder, by means of freezing and application of pressure, after homogeneous absorption of an aqueous alkali solution into the chitin powder at a low temperature.  
     CONSTITUTION: Water, in which a chitin powder is dispersed, is boiled at 0.1W 5kg/cm 2 , at 103W160°C, and then filterpressed. The obtained water-containing chitin powder is dispersed into a 20W60wt%, preferably about 40wt%, aqueous solution of NaOH or KOH. By applying pressure on the resulting aqueous solution of alkali chitin, it is impregnated with the alkali solution. Then the obtained alkali chitin is frozen at ≤-10°C, preferably ≤-20°C, by which the water within the micelle is crystallized and expanded, causing penetration of the alkali solution. Then it is thawed, and the solution is allowed to further penetrate by means of freezing at ≤15°C and application of pressure. Although it is possible to effect the penetration by means of one procedure, it is preferable to accomplish it by repeating the procedure, in oder to obtain effective results.
