Chemical Structure
Product Introduction:
Isophthaloyl chloride, also known as isophthaloyl dichloride, etc. It is a fine chemical and is often used as a pharmaceutical intermediate.
In general, it is a colorless or slightly yellow solid crystal. Soluble in ether, decomposed in water and alcohol.
Common preparation methods are:
Thionyl chloride method, phosphorus pentachloride method, phosgene method, dimethyl isophthalate chlorination method, isophthalic acid chlorination method.
However, the phosgene method is generally used, and the phosgenation reaction is usually carried out in the presence of a formamide-based catalyst. If the isophthalic acid is converted into an inter-molecular acid anhydride first, and then the phosgenation reaction is carried out, and the isophthaloyl chloride itself is used as the reaction solvent, a higher yield can be obtained.

Product Usage:
Isophthaloyl chloride is mainly used as the raw material of aromatic fibers, as intermediates of pesticides, medicines and polymers. It can also be used to manufacture aramid fibers, polyacrylates, heat materials, dyes, pigments, medicines and chemicals.
High-purity isophthaloyl chloride can be made use of as a monomer for polyamide, polyester, polyarylate, polyaramid, fluid crystal polymer, aramid 1313 (Nomex), etc. The downstream item aramid fiber manufactured by it has the advantages of heat resistance, fire resistant, insulation, wear resistance as well as good dimensional stability.
In addition to being used as a pharmaceutical intermediate, Isophthaloyl dichloride has been widely used in environmental protection, filtration, high-performance protective products and electrical insulation, honeycomb materials used in aircraft high-speed trains and other fields. At the same time, it can be used as modifier of high polymer.
