| abstract | 251,321. Dodd, H., Sprent, W. C., and United Alkali Co., Ltd. Dec. 29, 1924. Tetrachlorthioindigos are obtained by treating a dichlorbenzene with chlorsulphonic acid, reducing the dichlorbenzenesulphochloride to the dichlorthiophenol, condensing the latter with chloracetic acid in aqueous solution, and finally treating the dichlorthiophenolthioglycollic acid with sulphuric acid to convert it into tetrachlorthioindigo. According to an example, p-dichlorbenzene is the starting material and the reduction of the 2: 5-dichlorbenzenesulphochloride is effected with zinc or iron filings and dilute hydrochloric acid. |
