chlorobenzene method using chlorobenzene as a starting material, there are a method of reacting with sulfur and a method of reacting with hydrogen sulfide. (1) sulfur method (2) hydrogen sulfide method.
Diphenyl disulfide method a certain amount of diphenyl disulfide and iodobenzene were dissolved in ethyl acetate and irradiated with a low-pressure mercury lamp. The yield of the product was 12%.
from this product can be synthesized 2,4-chlorophenol, used for the synthesis of herbicide ether, 2,4 a drop, EPBP, toxic grams powder, such as mite ester; pharmaceutical for the synthesis of thiodidichlorophenol.

production method | mix 858G of anhydrous benzene and 464G of aluminum trichloride, cool to 10 °c, A solution of 405.1G of sulfur chloride and 390g of benzene was added with stirring. The reaction was started immediately, and hydrogen chloride was evolved, and a yellow viscous aluminum trichloride complex was precipitated. After completion of the reaction, the reaction mixture was ice-separated. The benzene layer was separated, and the dark oily matter after benzene evaporation was cooled to 0 ° C., and the precipitated sulfur was filtered off. The oil was then dissolved in methanol, cooled to 0 °c, and the precipitated sulfur was filtered off. The methanol solution continued to distill a small amount of low-boiling fraction after recovery of the methanol. The 155-170 °c (2.39kPa) fraction was then collected as a crude product. The crude product was heat-treated with zinc powder and sodium hydroxide, washed with water, dried, and finally distilled under reduced pressure to obtain 450-464G of diphenyl sulfide. |
