Abstract

6644. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. March 16. Aminothiazole monosulphonic acids are obtained by baking dehydrothiotoluidine or homologues or substitution products thereof or the corresponding primuline compounds with one molecular part or more of sulphuric acid, preferably in vacuo. Aminothiazole disulphonic acids are obtained by baking the above-specified aminothiazoles with two molecular parts or more of sulphuric acid, preferably in vacuo, or by sulphonating the monosulphonic acids described above with fuming sulphuric acid, or by baking the known monosulphonic acids of the aminothiazoles with one molecular part or more of sulphuric acid, preferably in vacuo. Monoazo dyes are obtained by combining the diazo compounds of the aminothiazole disulphonic acids described above with acetoacetic arylides. Products are specified from: dehydrothiotoluidine disulphonic acid and acetoacetic-o-anisidide; dehydrothio-m-xylidine disulphonic acid and acetoacetic-m-xylidide; acetoacetic chloranilide, p-anisidide, and cresidide, and primuline disulphonic acid, are also specified as components. The products dye cotton greenish-yellow shades.
