Abstract
Nitroso-compounds of oxyalkylated arylamines are obtained by treating the parent amines with nitrous acid and, in the case of secondary amines, treating the resulting nitrosamine with acid. By condensation with hydroxy bodies oxazines are obtained, and with amines, indamines, which may be converted into azines in the usual manner. Thiosulphonic acids of oxyalkylated amines are prepared by reducing the above nitroso-compounds and treating with sodium thiosulphate; they are converted into thiazines in the usual way. According to examples (1) dioxyethyl-m-aminophenol and dioxyethyl-m-amino-p-cresol are nitrosated in alcoholic solution; (2) thiosulphonic acids are obtained from nitroso-oxyethyl-aniline and nitroso-oxyethyl-o-toluidine and may be converted into thiazines by treatment with nitroso-Schaeffer acid and oxyethyl-o-toluidines respectively. Specification 181,750 is referred to.
