| titleOfInvention | The manufacture of new compounds for the treatment of textiles |
| abstract | Products stated to have emulsifying properties and to be useful as softening and cleansing agents in the textile industry are prepared by reacting a lower alkyl ester of an inorganic acid with a mercaptobenzthiazole which has an alkyl group containing at least eight carbon atoms in the 2-position and may carry substituents such as methyl, methoxy or ethoxy in the benzene nucleus. The lower alkyl ester may contain up to four carbon atoms. In examples: (1) 2-octadecylmercaptobenzthiazole, obtained by reacting octadecylbromide in butyl alcohol with the sodium mercaptobenzthiazole, is treated with dimethyl sulphate; the product may be used for softening cotton limbric; (2) 2-dodecylmercaptobenzthiazole, obtained by the interaction of dodecyl bromide and sodium mercaptobenzthiazole is treated with dimethylsulphate. The 2-alkylmercaptobenzthiazoles may also be prepared from the 2-mercaptobenzthiazoles by treating them with the sulphuric esters of higher alcohols. The following 2 - alkylmercaptobenzthiazoles are mentioned: 2-octadecyl, 2-dodecyl and 2-octadecenyl mercaptobenzthiazoles containing methyl or methoxy in the 6-position, or methyl in the 4-position.ALSO:Products stated to have emulsifying properties are obtained by reacting lower (up to C4) alkyl esters of inorganic acids with a mercaptobenzthiazole which has an alkyl group containing at least eight carbon atoms in the 2-position and may carry substitutent such as methyl, methoxy or ethoxy in the benzene nucleus. In examples 2-octadecylmercaptoand 2 - dodecylmercapto - benzthiazoles are treated with dimethylsulphate. The following 2-alkylmercapto benzthiazoles are mentioned: 2-octadecyl-, 2-dodecyl- and 2-octadecenyl-benzthiazoles containing methyl or methoxy in the 6-position or methyl in the 4-position. |
