PRODUCT DESCRIPTION

Epichlorohydrin is a sort of organochlorine compound as properly as epoxide. It can be used as an industrial solvent. It is a exceptionally reactive compound, and can be used for the manufacturing of glycerol, plastics, epoxy glues and resins, and elastomers. It can additionally be used for the manufacturing of glycidyl nitrate and alkali chloride, used as the solvent of cellulose, resins, and paint as properly as being used as an insect fumigant. In biochemistry, it can be used as a crosslinking agent for the manufacturing of Sephdex size-exclusion chromatography resins. However, it is a practicable carcinogen, and can reason a variety of types of facet results on respiratory tract and kidneys. It can be manufactured via the response between allyl chloride with hypochlorous acid as properly as alcohols.

Product Usage

Epichlorohydrin (ECH) is a highly reactive organochlorine compound and a versatile intermediate in the chemical industry. Its most prominent application is in the production of epoxy resins, which are essential for high-performance coatings, structural adhesives, and composite materials used in the electronics and aerospace sectors. In the paper industry, it is a key component in the synthesis of wet-strength resins, which enhance the durability of paper products when moist. Furthermore, ECH is utilized to manufacture synthetic glycerin and a variety of water treatment chemicals, including flocculants and ion-exchange resins. It also serves as a critical building block for elastomers like epichlorohydrin rubber, prized for its excellent fuel and oil resistance.
