Synthetic method of naphthaquinone sulfonyl chloride

-

Paragraph 0030, (2017/01/12)

The invention discloses a synthetic method of naphthaquinone sulfonyl chloride, belonging to the technical field of organic synthesis. According to the synthetic method, naphthaquinone sulfonyl chloride is synthesized from naphthaquinone sulfonyl chloride in an inert solvent in the presence of a catalysis amount of initiator by taking di(trichloromethyl)carbonic ester as an acylating chlorination reagent. Highly corrosive materials such as chlorosulfonic acid, thionyl chloride and the like are not used in the reaction process, and a large number of sulfur dioxide, hydrogen chloride gas and acid wastewater are not generated in the reaction, so that the treating stresses of water gas and wastewater are relieved, the environment is protected, the corrosion resistance requirement of industrial equipment is reduced, and the safe operation of the equipment is guaranteed.

Sulfochlorination of 1,2-Naphthoquinone-(2)-diazide by Chlorosulfonic acid

Sauer, E.,Polz, K.,Schopf, G.,Bendig, J.

, p. 467 - 473 (2007/10/02)

The sulfochlorination of 1,2-naphthoquinone diazide-(2) (1) by chlorosulfonic acid was investigated.The yields of the formed products (1,2-naphthoquinone diazide-(2)-4-sulfonic acid (4), 1,2-naphthoquinone diazide-(2)-5-sulfonic acid (5), 1,2-naphthoquinone diazide-(2)-4-sulfochloride (2) and 1,2-naphthoquinone diazide-(2)-5-sulfochloride (3)) depend on the temperature and on the time of reaction.The highest yields of the favoured 1,2-naphthoquinone diazide-(2)-4-sulfochloride (2) are obtained at 63 deg C and after a reaction time of 80 minutes (50percent).
