Abstract

1359006 Sulphur-containing ethers EASTMAN KODAK CO 5 July 1971 [6 July 1970] 31389 71 Heading C2C [Also in Division G2] Bis-(2-vinylsulphonylethyl) ether is prepared by dehydrohalogenation of 2,2<SP>1</SP>-bis-(2-chloroethylsulphonyl) ethyl ether. 2,2<SP>1</SP>-Bis-(2-chloroethylsulphonyl) ethyl ether is prepared by treating the corresponding diol with thionyl chloride while refluxing in acetonitrile containing N,N- dimethylformamide. 2,2<SP>1</SP>-Bis-(2-hydroxyethylsulphonyl) ethyl ether is prepared by oxidizing the corresponding disulphide by hydrogen peroxide. 6-Oxa-3,9-dithioundecane-1,11-diol is prepared by reacting sodium 2-hydroxyethylmercaptide with bis-(2-chloroethyl) ether in methanol and evaporating the solvent. Bis-(vinylsulphonylmethyl) ether and bis-(4-vinylsulphonylbutyl) ether are prepared similarly. The unsaturated products are used as photographic hardeners.
