| Abstract: | Chitin is the second most abundant natural polymer in the world.Hydroxyethyl chitin is a water soluble chitin derivative which is prepared by etherification of chitin.In this gas-solid reaction,Gasrous ethylene oxide was used as etherification reagent to react with alkali-chitin.13C-NMR and IR spectra of chitin and Hydroxyethyl chitin show that hydroxyethyl chitin is prepared.The amount of water-solubility of hydroxyethyl chitin increases with the Increase of substituting degree,which shows linear reactionship. |

| Keywords: | chitin hydroxyethyl chitin gas-solid reaction ethylene oxide water-solubility |
