Synthesis method

1. Using phenol as raw material, it is first chlorinated to generate 2,4-dichlorophenol, and then sulfurized with sulfur monochloride to generate sulfur bisdichlorophenol. (1) Chlorination: 2,4-dichlorophenol is produced by reacting phenol with chlorine: First, melt the phenol and pass dry chlorine gas at 57-63°C for 35 hours. After the reaction is completed, 2,4-dichlorophenol is obtained. The yield can reach about 91.5%.

(2) Sulfided dichlorophenol React with sulfur monochloride in the presence of trichlorethylene and anhydrous aluminum trichloride to obtain sulfur bisdichlorophenol: add dichlorophenol, trichlorethylene, and anhydrous aluminum trichloride in the tank in sequence at 50 Add sulfur monochloride at ±2°C, complete the addition in about 2.5 hours, and then react at a constant temperature for 2 hours. Filter, wash with trichlorethylene and dry to obtain crude sulfur bisdichlorophenol. The yield can reach about 51.3%.

(3) Refined reaction Add crude sulfur bisdichlorophenol into the tank, then add sodium hydroxide solution, heat to dissolve, then cool to 0°C, add sodium chloride, stir to salt out, add saturated sodium chloride solution, and stir evenly. Leave to stand, filter, wash with saturated sodium chloride solution, and recover to obtain sodium thiobisdichlorophenate. Then dissolve it in distilled water, filter it, stir and add 3.5% hydrochloric acid at about 80°C to precipitate, let it stand, and separate the supernatant liquid. The precipitate is washed with distilled water until the pH value is 2, filtered, washed with water until the pH value is about 7, and dried to obtain thiobisdichlorophenol.

2. Using phenol as raw material Chlorination and sulfurization yield dichlorophenol sulfate.
Dry chlorine gas was passed into the molten phenol (57-63°C). After 35 hours, the yield of 2,4-dichlorophenol reached 91.5%. Then add dichlorophenol, trichlorethylene, and anhydrous aluminum trichloride to the reaction kettle, pass sulfur dichloride (SOCl2) at 48-52°C for 2.5 hours, and react at a constant temperature for 2 hours. After cooling, filter, wash with trichlorethylene, and dry to obtain crude thiochlorophenol. Dissolve crude thiochlorophenol in hot sodium hydroxide solution, add salt to salt out after cooling, and wash with saturated brine to obtain sodium thiochlorophenol. Sodium thiochlorophenol is dissolved in water, filtered and precipitated by adding dilute hydrochloric acid. After standing, filter out the precipitate, wash with water until neutral, and dry to obtain the finished product.
