| production method | is obtained from sodium methylnaphthylamine -4-sulfonate through the following steps. Dissolve sodium methylnaphthylamine -4-sulfonate in water, add concentrated hydrochloric acid, add sodium nitrite at 0 ℃ for diazotization, then add cuprous chloride and hydrochloric acid solution to diazonium salt, heat replacement, cooling, filtration, washing with water, drying below 100 ℃, slowly add the dried sodium 1-chloronaphthalene-4-sulfonate to phosphorus pentachloride and reflux for 2 hours, pour it into crushed ice to drain, wash with water, and dry in air; the obtained 1-chloronaphthalene-4-sulfonyl chloride was added to phosphorus pentachloride once, heated to 160-165 ℃ for 4h, poured into crushed ice to be neutral, and finally distilled under reduced pressure, and ethanol recrystallized to obtain the finished product. |
