By the glycolation of chitin with ethylene oxide, the glycol chitin, which is a new derivative of chitin, was prepared. (1) Alkali chitin was dispersed in NaOH solution by stirring vigorously with ice at 0°. After the concentration of NaOH in the dispersed solution was made to 13% and an equal or less amount of ethylene oxide to the amount of chitin used was added to it, this dispersed solution was kept at 33° for one or two hours. The glycol chitin thus obtained is easily soluble in water and gives an extremely viscous solution. (2) It is a mono-hydroxyethyl ether of chitin in which only the primary hydroxyl groups of chitin were selectively glycolated.
