Basic knowledge of chitin

Today, let's introduce the basic knowledge of chitin:

English name: Chitin

Alias: chitin, chitosan, shell protein, polyacetamide glucoses.

Character: White or light yellow flakes. The main components of the hard horny and exoskeleton of insects and crustaceans. Soluble in concentrated hydrochloric acid, sulfuric acid, glacial acetic acid and 78g 97% phosphoric acid, almost insoluble in water, dilute acid, alkali, ethanol and other organic solvents. Half lethal dose: rats, intravenous injection, 50 mg / kg.

Application: it can be used as polishing agent, filler, emulsifier and so on in industry. In agriculture, plant seeds are encapsulated in chitin to prevent fungi from invading and thus to improve plant disease resistance. Chitin was treated with acylation, propylene and halogenation to form derivatives soluble in organic solvents. The derivatives can be used as coatings or fillers for electronic components and for the manufacture of contact lens sheets which only need to be formed in the casting die to produce thin films or forming fibers with good flexibility, conductivity, wettability and biological adaptability. This material can also be widely used in the synthesis of medical polymer materials, such as microcapsules for pharmaceutical manufacture, surgery Surgical sutures, tissue binders, artificial renal membranes, artificial skin, etc. Chitin deacetyl derivatives have strong germicidal ability and can be used for storage and preservation of cooked food and fresh food. Deacetylated chitin can also increase color, fixation, make food, cosmetics and fabrics more bright and maintain long-term non-decolorization. The salt formed by the reaction of this derivative with formic acid and acetic acid can be used as the medium of affinity chromatography, the carrier of immobilized enzyme, the ion exchange agent and so on, and can also be used as the hair-fixing agent.

Storage: sealed, cool and dry.

The material comes from the network.
