PRODUCT INFORMATION GAS NO： 9012-76-4 EC NO： 222-311-2 Formula： (C6H11NO4)n=(161)n Molecular Weight： 161·n CHARACTER Non-Toxic and Odorless.Off-White or slight yellow powder.Soluble in acid,and insoluble in water,base or normal organic solutions. APPLICATION（ONLY FOR REFERENCE ） Application of chitosan in light industry:Taking advantage of the solubility and film-forming property of chitosan as well as the interconvertibility of its chemical structure,acetic anhydride was used as the transformation fixing agent of chitosan-chitin,thus a new type of chitin-type fabric finishing agent without formaldehyde was prepared, which has preferable mechanical strength and chemical stability. Application in environmental protection:Chitosan can be used to treat industrial wastewater and extract heavy metals.Stable chelates can be formed by amino groups, hydroxyl groups and metal ions in molecules, which can be widely applied in the recovery of precious metals, industrial wastewater treatment and other aspects. Soluble chitosan with high viscosity was prepared by chitosan, and the obtained product was of high viscosity, good quality, no toxicity, biodegradability and no secondary pollution.
