Title: Manufacture of dyestuffs
IPC: C09B49/12
Filed: 1924-05-08
Abstract: Sulphuretted dyes are produced by treating a 2 : 5-diarylidobenzoquinone, other than a 3 : 6-dihalogen-2 : 5-diarylidobenzoquinone, with a sulphur halide such as the mono or dihalide, or with a sulphurous acid halide such as thionyl chloride; the reaction may take place in presence of a solvent or diluent, with or without an acid-binding or condensing agent, and at ordinary or high temperatures.  The products dye wool from the vat in yellow, orange, brown, violet, greenish, and black shades. At high temperature products of darker tone result.  Particularly suitable are the 2 : 5-diarylidobenzoquinones substituted in the 3- or 6-position; they yield deeply-dyeing products with one molecular proportion or less of sulphur halide; the unsubstituted diarylidobenzoquinones require larger proportions of sulphur halide (2-3 mol.), but a large excess is to be avoided.  The parent arylidoquinones are obtained by the known methods and may be substituted at the nitrogen, or in the aryl nuclei by substituents such as halogen, alkyl-, alkoxyl-, phenyloxy-, nitro-, amino-, alkylamino-, aralkylamino-, phenylamino-, hydroxyl-, or carboxyl.  As diluents, which may also act as condensing agents, are specified nitrobenzene, a -chlornaphthalene, chlorbenzene, benzene, sulphuric acid, chlorsulphonic acid, formic acid, and acetic acid; magnesia is mentioned as an acid-binding agent.
