Abstract
254,708. Soc. of Chemical Industry in Basle. July 3, 1925, [Convention date]. Monoazo dyes and chromium compounds thereof.-Monoazo dyes are obtained by coupling an unsulphonated o-oxydiazo compound with an unsulphonated 1-aryl-5-pyrazolene, at least one of the components containing a sulphamido group. The products may be converted into chromium compounds by treating with agents which yield chromium; these dya wool, particularly loose wool or cardings, very equal orange tints fast to fulling and light. In examples 6-nitro-2-aminophenol-4-sulphamide (obtained by nitrating 2- aminophenol-4-sulphamide) is diazotized and coupled with 1-phenyl-3-methyl-5-pyrazolone and 2-aminophenol-4-sulphamide is diazotized and coupled with 1- (3<1>-sulphamido) -phenyl-3- methyl-5-pyrazolone; the dyestuffs from 4-nitro-2- aminophenol and 1-(3<1>-sulphamido)-phenyl-3- methyl- (or carboxyl) -5-pyrazolone are also referred to. In further examples, the dyestuff from 2-amirophenol-4-sulphamide and 1- (3<1>-sulphamido) -phenyl-3-methyl-5-pyrazolone is treated with chromium formate or sodium chromate, the dyestuff from 6-nitro-2-aminophenol-4-sulphamide and 1-phenyl-3-methyl-5-pyrazolone is treated with chromium acetate, and the dyestuff from 2-aminophenol-4-sulphamide and 1- (3<1>- sulphamido) - phenyl-5-pyrazolone-3-carboxylic acid is treated with a paste containing hydrated chromium oxide, caustic potash and glycerine, to yield the corresponding chromium compounds. Specifications 126,460 and 210,699 are referred to.
