What isterephthaloyl chloride?

1. Terephthaloyl chloride is an ancient compound that was synthesized as early as the beginning of the 20th century. It has been developed and utilized on a large scale for nearly two or three decades. In recent years, terephthaloyl chloride has become an important intermediate material and is widely used in the synthesis of man-made fibers and pesticides. At present, the herbicide diquat, which is synthesized by using terephthaloyl chloride as a raw material, has an annual output of about 1,000 tons in the United States and Japan. The polyparaphenylene terephthalamide fiber obtained by polycondensation of terephthaloyl chloride and p-phenylenediamine has excellent properties such as high strength and high modulus, and is a kind of man-made fiber with wide application, which has caused various aspects. Value.

2. Terephthaloyl chloride (referred to as TPC) is a needle that is rapidly hydrolyzed by moisture in the air to form the corresponding acid. The purity of terephthaloyl chloride directly affects the properties of the product synthesized therewith. At present, terephthalic acid chloride is mainly produced from terephthalic acid, and can be classified into a phosgene method and an ester chlorination method depending on the chlorinating agent used.

Terephthaloyl chlorideUsage
