    Abstract: Compounds of the 1,3,4-thiadiazole, 1,3-benzothiazole, 1,3-benzoxazole and pyrimidine series, wherein is present once or twice a chlorine atom in an a -position to a ring nitrogen atom, are obtained by treating a corresponding mercapto compound with phosgene and accelerating the decomposition of the intermediate adduct which is formed by heating the reaction mixture and/or by the addition of an N-substituted amide of the formula wherein R1 denotes a hydrogen atom or an alkyl group with from 1 to 5 carbon atoms, R2 and R3 denote alkyl groups with from 1 to 4 carbon atoms or R1 and R2, when taken together, denote a tri- or tetra-methylene group, or R2 and R3, when taken together, denote an alkylene group with from 2 up to 8 carbon atoms. The reaction is usually carried out in an inert solvent, many of which are specified, having a boiling point between 35 DEG and 250 DEG C., and may be effected at normal or raised pressure. Besides the parent compounds of the specified heterocyclic series, derivatives thereof are mentioned containing methyl, phenyl, methoxyl and chloro groups as substituents. Substituted amides specified are dimethylformamide, N,N1 - dimethylacetamide, N,N1-dibutylformamide, N,N1-tetramethyleneformamide, N-methylpyrrolidone and N-butylpyrrolidone. Examples illustrate the preparation of 2-chloropyrimidine, 2-chloro-4-methylpyrimidine, 2 - chloro-4,6-dimethylpyrimidine, 2 - chlorobenzothiazole, 2 - chlorobenzoxazole and 2,5-dichloro-1,3,4-thiadiazole. The compounds obtained are intermediates in the production of dyes.

    Abstract: Polyacrylonitrile materials are dyed with a dye formula in which R1 and R2 are alkyl groups having 1-3 carbon atoms which may be substituted and X is an anion of a simple or complex inorganic or organic acid. Copolymers of polyacrylonitrile e.g. with methyl acrylate, methylvinylpyridine and vinyl acetate are also dyed. Dyeing is generally carried out at pH 1-7 at the boil, blends of wool or polyester are referred to, green-blue shades are obtained.

    Abstract: The invention comprises water-soluble azo dyes of formula wherein A is the radical of a carbo- or heterocyclic diazo component, R1 is a substituted or unsubstituted aliphatic, araliphatic or phenyl radical, R2 is a hydrogen atom or an aliphatic or phenyl radical, X is a water-solubilizing group, Y is a reactive group capable of forming a covalent link between the dye and a fibre containing functional groups, Z is a hydrogen, chlorine or bromine atom or a methoxy, acetyl, amino, thiocyano, carboxymethyleneoxy or sulphonamide group, n is 1, 2 or 3, m is 0, 1 or 2 and when m is 0 the dye contains at least one group which will react with a polyfunctional reactive compound (i.e. a compound which will react with both the dye and a fibre to form covalent links with each) under normal dyeing conditions for reactive dyes (see Division D1). The dyes are prepared by the axial coupling processes or by treating dyes wherein m is 0 with, for example, cyanuric chloride or its primary condensation products. Many reactive groups and polyfunctional reactive compounds are specified. The dyes are used to colour wool, silk and polyamide fibres and in particular cellulose fibres by the usual processes for reactive dyes. Specification 958,659 is referred to.ALSO:Azo dyes of formula wherein A is the radical of a carbo- or heterocyclic diazo component, R1 is a substituted or unsubstituted aliphatic, araliphatic or phenyl radical, R2 is a hydrogen atom or an aliphatic or phenyl radical, X is a water-solubilising group Y is a reactive group capable of forming a covalent link between the dye and a fibre containing functional groups, Z is a hydrogen, chlorine or bromine atom or a methoxy, acetyl, amino, thiocyano, carboxymethyleneoxy or sulphonamide group, n is 1, 2 or 3 and m is 0 1 or 2 and when m is O the dye contains at least one group which will react with a polyfunctional compound are used to dye and print nitrogenous and, preferably, cellulose fibres in acid or alkaline medium when required together with polyfunctional reactive compounds (i.e. compounds which will react with both the dye and the fibre to form covalent links with each). Specified polyfunctional compounds include (a) alkaline medium:-butachiene dioxide, cyanuric chloride and hexahydro-1,3,5-triacryloyl-s-triazine (b) acid medium:-visable aminoplast-forming substances containing groups of formula wherein X is O, S, NH or ­N,R4 is hydrogen, or aryl or an aliphatic radical which may form a ring with the nitrogen and carbon atoms and R1 is alkyl or hydrogen, such as dimethylolurea, dimethyloldicyano-diamide, methylolthioured, dimethylolguanidine and trimethlol-melamine. In Example (19) the dye 2-ammonaphthalene-4, 8-disulphonic acid --> 1-(3-amino-n-propyl)-2-phenylindole is pasted with hexahydro-1,3,5-triacryloyl-s-triazine, polyvinyl alcohol, formaldehyde-naphthalene-sulphonic acid condensate, urea, water, sodium bicarbonate and sodium alginate, the paste printed on cotton and steamed to give a yellow print. In Example 20 the reactive dye of Example 10 is employed to dye cotton in conventional manner.

    Abstract: Disazo dyes with an indole coupling component useful for dyeing polyamide and polyurethane articles have the general formula in which R1 is a methyl or phenyl group, R2 is H or a methyl group and m is 1 or 2 and in which the rings A and B may contain other non-water-solubilizing groups, e.g. alkyl, alkoxy or acetylamino groups or halogen atoms. The dyes may be prepared conventionally by diazotization and coupling. A number of suitable diazo and coupling components are listed.ALSO:Textile materials of synthetic polyamides or polyurethanes are dyed or printed using the dyestuff in which R1 is a methyl or phenyl group, R2 is a hydrogen atom or a methyl group, m is 1 or 2 and the rings A and B may be further substituted with non-water-solubilising groups, e.g. halogen atoms or alkyl, alkoxy or acetylamino groups. The dyes have poor solubility in water and may be applied as a dispersion in a weakly alkaline to strongly acid bath at temperatures of 90-100 DEG C. or higher under super atmospheric pressure in the presence of usual auxiliaries, e.g. sulphonated sperm oil alcohol or a castor oil/ethylene oxide adduct (1 : 40). Printing is carried out conventionally; the print paste may contain auxiliaries, e.g. resorcinol or b -naphthol. The dyeings are dischargeable with usual reducing agents. Examples are given.
