Title: The Manufacture or Production of New Azo Colouring Matters and of Intermediate Products for Use therein.
Inventor: NEWTON HENRY EDWARD
Filed: 1901-06-08
Granted: 1902-05-01
Abstract: 11,766. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. June 8. p-p-Diamidodiphenylurea disulphonic acid of the formula is produced by causing phosgene to act upon nitrometanilic acid (NH2 : SO3H : NO2 = 1 : 3 : 4) in presence of a condensing-agent, such as sodium carbonate, and then reducing the resulting dinitro compound, for example, by means of iron filings. The new product is precipitated from a sodiumcarbonate solution by hydrochloric acid as uncoloured needles soluble with difficulty in water. Alternatively, phosgene may be caused to act upon p-phenylenediamine monosulphonic acid whereby the same product is produced. Dyes, artificial.-New disazo dyes, which dye unmordanted cotton red to violet-red shades fast to light, are produced by combining the tetrazo derivative of the foregoing diamido diphenylurea disulphonic acid with #1alpha4-amidonaphthol, its sulphonic acids, or the alkylized derivatives of these compounds, in neutral or acid solutions. Examples are given in which bright-red and violet-red dyes are obtained from #1alpha4-amidonaphthol-#3-sulphonic acid and #1alpha4-amidonaphthol, respectively. The same disazo dyes are also produced by causing phosgene to act upon a solution in sodium carbonate, or the like, of two molecular proportions of monoazo dyes, which are obtained either by combining the diazo compound of p-nitraniline-osulphonic acid with #1alpha4-amidonaphthol, or a derivative thereof, and then reducing the product, or by splitting of the acetyl group from the corresponding monoazo dyes obtained from acetylized p-phenylenediamine monosulphonic acid.
