    Abstract: 1,156,158. Hydroxy alkane- and alkenenitriles. BADISCHE ANILIN- & SODAFABRIK A.G. 16 Nov., 1966 [17 Nov., 1965], No. 51327/66. Heading C2C. Nitriles of hydroxyalkane- and hydroxyalkene-carboxylic acids, in which the hydroxy group is separated from the nitrile group by at least 6 carbons, are obtained by heating the corresponding hydroxyalkane- or hydroxyalkene-carboxylic acids, the ammonium salts or the amides thereof in the presence of at least 2 moles of ammonia per mole of acid or at least one mole of ammonia per mole of the ammonium salt or amide of the said acid to a temperature of 250-400‹ C. in the absence of dehydration catalysts at a pressure of 50-150 atmospheres. The ammonia is preferably used in an amount of 10-30 moles per mole of acid, ammonium salt or amide and water or steam may be added to the reaction mixture. In examples, 7-hydroxy-enanthic acid and ricinoleic acid are converted to the corresponding nitriles.

    Abstract: The invention comprises dyes of formula wherein B is a CH2=CH-CO- or A-CH2-CH2-CO residue and A is the radical of an organic textile dye with the proviso that the said radical contains at least one sulphonic acid group directly attached to the anthraquinone nucleus when A is the radical of an anthraquinone dye. The dyes are prepared by reacting appropriate dyes or compounds capable of coupling or diazotizable aromatic or heterocyclic amines or N-formyl derivatives thereof, which contain in the molecule at least one reactive hydrogen atom, preferably linked via an oxygen, nitrogen or sulphur atom, or a methylene ether nitrogen or sulphur atom, or a methylene ether or methylene ester group with hexahydro-1,3,5-triacryloyl-s-triazine or with compounds convertible thereto under the reaction conditions, the reaction being conducted in an alkaline aqueous and/or organic solution or suspension at temperatures up to 200 DEG C. The diazotizable amines and coupling components so obtained, if necessary after removal of the N-formyl group by hydrolysis, are converted into azo dyes by the usual coupling procedures. The dyes are used as reactive dyes in the dyeing and printing of cellulose, natural and synthetic polyamide, polyvinyl alcohol, leather, paper and polyacrylonitrile materials. The preparation of dyes of the monoazo, metallized azo, phthalocyanine, xanthene and anthraquinone series is specified in examples.

    Abstract: Benzene carboxylic acids, anhydrides or mixtures thereof are prepared by liquid phase oxidation, with molecular oxygen at an elevated temperature in presence of an oxidation catalyst and gamma-butyrolactone as solvent, of benzene derivatives, optionally nuclear-substituted by chlorine or carboxyl, which contain 1-3 C1-3 side chains selected from alkyl monochloralkyl, dichloroalkyl and hydroxyalkyl groups. In examples, benzoic acid is obtained from toluene or benzyl alcohol, terephthalic acid from p-xylene, p-cymene or p-toluic acid, isophthalic acid from m-xylene, p-chlorobenzoic acid from p-chlorotoluene and phthalic anhydride from o-xylene, using promoters selected from Co 2-ethylhexanoate + NH4Br or isobutyraldehyde, Cr (III) nitrate + Co (II) phosphate, and NH4VO3 + NaBr. Other specified starting materials are: trimethylbenzene, cumene, diisopropyl benzene, chloromethylbenzene xylyl chloride and xylylidene and xylylene dichlorides. Specifications 737,439, 762,849 and 798,342, also U.S.A. Specification 2,245,528 and German Specification 767,366 are referred to.
