Traits: white or light yellow sheet is the main component of insects and crustaceans hard and horny exoskeletons dissolved in concentrated hydrochloric acid, sulfuric acid, glacial acetic acid and 78% to 97% phosphoric acid, almost insoluble in water, dilute. acid, alkali, ethanol and other organic solvents. median lethal dose (rat, intravenous) 50mg / kg. deacetylation of chitin which is the product of chitosan, chitin because of its different sources, there are three kinds of structure -α , β and ν. α- chitin between molecular chains arranged in an antiparallel fashion, with strong inter-molecular hydrogen bonding. β- chitin between the main chain are arranged parallel to each other, than between molecules weak. γ- chitin molecule, the molecular structure of both of the preceding two. α- chitin extracted from shrimp and crab shell chitin. β- chitin mainly by fish or squid soft feathery body shell isolated get
Uses: scientific research, experiment can be used for chromatographic carrier, environmental protection, radioactive contamination purification, comprehensive utilization of mineral, glass fiber finishing agent, made of polymer-based dyes, paper industry, additives, other fabric finishing agents, photographic industry material
