Abstract: New heterocyclic disazo dyes are of formula (I): (in which D is the gp. of a diazo component; R is H, OH opt. substd. alkyl, cycloalkyl, aralkyl, aryl or heteroaryl; R' and R2 are H, opt. substd. alkyl, alkenyl, cycloalkyl, aralkyl or aryl; X is N, or a C atom carrying a -COO-alkyl(1-4C), -CN or -CONR1R2) (I) are used for dyeing of synthetic and cellulosic fibres, esp. cotton, polyesters and their blends in greenish blue to black shades.

Abstract: Prodn. of 1-aminoanthtraquinone-2-carboxylic acid (I) involves the oxidn. of 1-amino-anthraquinones (II) of the formula (I) (in which Z is Me, CH2OH, CHO, CH2NHR' or CH2NR'R", R' and R" are linear or branched 1-6C alkyl or complete a pyrrolidine, piperidine or morpholine ring). Oxidn. is carried out with air and/or oxygen in a water-miscible polar aprotic solvent (III) at normal press. in the presence of strongly basic cpds. (IV) at -25 to +60, pref. -10 to +30 degrees C. In an example a soln. of 1-aminoanthraquinone-2-aldehyde in DMF was treated with t-BuOK at room temp. and air was introduced for 2h. Slightly impure (I) was obtd. in ca. 100% yield. (I) is an intermediate for the prodn. of dispersion, pigment and vat dyestuffs. The process can be carried out easily on the technical scale in ordinary reactors.

Abstract: Halogen-substd. anthraquinones are obtd. by the gas phase oxidn. of diphenylmethane cpds. of formula (I):- (where R1-3 are each H or an aliphatic gp; X aY are each halogen, or the Y gps. and one X gp. may be H) in the presence of a catalyst contg. TiO2 and/or ZrO2 and V2O5 in a wt. ratio of 0.004-0.75 pt. V2O5 based on 1 pt. TiO2 and/or ZrO2. The prods. are useful as raw materials esp. for the prepn. of substd. anthraquinones. The hitherto difficulty obtainable 1-chloroanthraquinone may now be obtained from mono-, di- and polyhaloanthraquinones. The aminoanthraquinones which are also obtainable, are useful in the prepn. of vat dyes and light fast lacquer pigments. In an example, mixt. of 5- and 6-chloro-2-methyldiphenylmethane was oxidise to give a mixt. of 1- and 2-chloroanthraquinone in a 1:7 ratio.

Abstract: Sulphur bridge contg. polymers are of formulae (III) and (IV): Y is p-phenylene, R1, R2 are each 1-20C (un)satd. aliphatic, cycloaliphatic, heterocyclic or aromatic radical, S, SO, SO2, CO or O can exist as hetero bridges; n is 5-1000; X is Cl, Br or I. (IV) is prepd. by heating (III) to >80 degrees C. (III) and (IV) can be prepd. without salts arising which have to be removed. The degree of polymerisation can be 10-100. Solns. of (IV) can be used as water resistant lacquers for e.g. wood, metal and cement products. In an example, methylthiohydroquinone was reacted with a dicarboxylic acid e.g. maleic acid to give a dithioether (I). 360 pts. of (I) was reacted with a dihalide e.g. Br-(CH2)6-Br, to give a water sol. polymer which an heating to 100 degrees C for 10 mins. resulted in a water-insol. polymer contg. S bridges. No salt was produced.

Abstract: Prepn. of pigments of formulae (I) and (II): (in which R is H, Cl, Br Me, OMe, OEt or SO2Me) by condensn. of 2 mols. o-aminophenol of formula: with 1 mol. acid or formula: or its anhydride or 1-4C alkyl diester, in N-methyl pyrrolidone (I) as reaction medium and in absence of alkali. High yields of pigment are obtd. of high purity giving improved brilliance and fastness compared with that from known processes of condensn. in other solvents in presence of acid acceptors.

Abstract: New 2-amino-pyrazolo-(3,4-d)thiazoles of formula (I): (where R1 is H, opt, substd. alkyl cycloalkyl, aralkyl, aryl, acyl or sulphonyl, R2 is opt. substd. alkyl, cycloalkyl, aralkyl, aryl or heteroaryl and R3 is H, 1-4C alkyl or opt. substd. Ph) are useful as starting matls. in prepn. of dyes where they serve as disazo components. (I) is prepd. by dehydrogenating cyclisation of cpds. having formula (II): in soln. or suspension at 5-150 (0-80) degrees C.

Abstract: Process for halogen substituted o-benzoylbenzoic acids from indanes of general formula (I) by oxidising with nitric acid and/or hexavalent chromium cpds. using 1.5 times the stoichiometric ratio in relation to the indane. (R1, R2, R3 are alkyl and R1, R3 may also be H, X and Y are both halogen or one may be H. Also di-halogen substituted o-benzoylbenzoic acids with the halogen atoms on each benzene ring ortho or meta to the carbonyl gp. specifically 2-(o-chlorobenzyl)-6-chlorobenzoic acid) (I) are used as intermediates for anthraquinones the process is simpler and cheaper than the Friedel Craft method.
