In this step, the concentration, dosage, reaction temperature and duration of the sulfonating agent are all important factors. It must be precisely controlled to obtain high-yield naphthalene- Naphthalene-1-sulfonic acid is then converted into naphthalene-1-sulfonyl fluoride. Naphthalene-1-sulfonyl chloride is often formed by combining thionyl chloride or phosphorus oxychloride with naphthalene-1-sulfonic acid. Taking thionyl chloride as an example, an appropriate amount of catalyst, such as N, N-dimethylformamide, is added to the reaction system and heated to 60-80 ° C. Naphthalene-1-sulfonic acid and sulfoxyl chloride are substituted to escape sulfur dioxide and hydrogen chloride gas to obtain naphthalene-1-sulfonyl chloride. After
, the fluorinating agent should be mixed with naphthalene-1-sulfonyl chloride. Commonly used fluorinating agents such as potassium fluoride are used in polar aprotic solvents such as dimethyl sulfoxide, and the temperature is controlled at 80-100 ° C. The chlorine atom of naphthalene-1-sulfonyl chloride is replaced by the fluorine atom, and the final product is naphthalene-1-sulfonyl fluoride. After the reaction, the product is purified by distillation, extraction, recrystallization, etc., to obtain high-purity naphthalene-1-sulfonyl fluoride.
