Level: br

Total nitrogen: 6.0 ~ 7.0%

Burning residue: ≤ 1.5%

Properties: off white or light yellow flakes or strips or powder. It is the main component of the hard cutin and exoskeleton of insects and crustaceans. Soluble in concentrated hydrochloric acid, sulfuric acid, glacial acetic acid and 78% ~ 97% phosphoric acid, almost insoluble in water, dilute acid, alkali, ethanol and other organic solvents. LD50 (rat, intravenous) 50mg / kg. The deacetylated product of chitin is chitosan. Chitin has three structural forms due to its different sources- α,β and ν.α- Chitin chains are arranged in an antiparallel manner and have strong intermolecular hydrogen bonding force. β- The main chains of chitin molecules are arranged in parallel with each other, and the interaction between molecules is weak. γ- Chitin molecule has both the above two molecular structures. α- Chitin is a chitin extracted from shrimp and crab shells. β- Chitin can be isolated from the feather shell of squid or squid

Purpose: biochemical research. It can be used as chromatographic carrier, environmental protection, purification of radioactive pollution, comprehensive utilization of ore, glass fiber finishing agent, high polymer dyes, additives in papermaking industry, finishing agents for other fabrics and photographic industrial materials
