Introduction
Terephthalyl chloride has a variety of uses. It is an important intermediate in the synthesis of a variety of organic compounds, such as terephthalimide, which can be used to prepare cellulose acetate, dyes and other chemicals. In addition, it can also be used as an acid chlorinating agent (e.g., to convert alcohols, amines, etc., into compounds such as esters, amides, etc.).
Terephthalyl chloride is a toxic compound, and contact or inhalation of it may cause irritation of the eyes, skin, and respiratory tract. Therefore, appropriate safety measures such as wearing protective eyewear, gloves and protective masks should be taken when using terephthalyl chloride to ensure that it is operated in a well-ventilated area.
