Superiority

1398-61-4 - Physico-chemical Properties

• is an off-white amorphous powder, odorless and tasteless. Can be dissolved in lithium chloride containing 8% of dimethyl acetamide or concentrated acid; Insoluble in water, dilute acid, alkali, ethanol or other organic solvents. Nitrogen content of about 7. 5%, high-speed stirring water swelling. Formation in water is better than cellulose. Dispersed phase, has a strong ability to adsorb fat. Deacetylated chitosan is soluble chitin. In nature, chitin is widely found in the shells of crustaceans such as lower plant fungi, shrimp, crab and insects, and in the cell walls of higher plants.
• It is a linear polymer polysaccharide, that is, a natural neutral mucopolysaccharide. If the acetyl group is removed by concentrated alkali treatment, chitosan is obtained. Chitin is chemically inactive, does not change with body fluids, does not cause foreign body reaction to tissues, non-toxic, with anti-thrombotic, high temperature Disinfection and other characteristics. Chitosan is alkaline polysaccharide, acid, anti-inflammatory effect, can reduce cholesterol, blood lipids.

1398-61-4 - Preparation Method

Open Data Verified Data

remove debris from shrimp and crab shells, clean them, dry them in the sun, and soak them in 5% hydrochloric acid to remove inorganic salts (calcium carbonate, calcium phosphate, etc.), then wash off residual acid with clear water. Then use 10% sodium hydroxide solution to remove impurities such as fat and protein.
Add dilute potassium permanganate solution bleaching decolorization, and then washed with water, and 1% of sodium bisulfite elution of residual potassium permanganate, after washing, drain, drying, can be prepared chitin.

1398-61-4 - Introduction

Chitin is a kind of polysaccharide that exists in many organisms, especially crustacean shells, so it is also called chitin. It is a natural polymer, and the monomer that makes up this polymer is 2-acetamido-2-deoxy-β-D glucose, so the scientific name of chitin is polyacetaminoglycos.
