    Abstract: A process for the production of an Alpha - omega -dialdehyde, comprising reacting a cyclic mono-olefin in the gaseous phase with oxygen at an elevated temperature. Preferably cyclopentene or cyclohexene respectively give glutardialdehyde and adipic dialdehyde by passage through a tubular reactor with air at 0.05 to 100 atmospheres and 200* to 500*C.

    Abstract: 3-HALOGEN- AND 3,5-DIHALOGEN-PHENOLS ARE PREPARED FROM HIGHERHALOGENATED COMPOUNDS HAVING THE FORMULA

    WHEREIN X represents halogen, R1, R2, R3 and R4 independently of one another represent hydrogen, halogen an alkyl, aralkyl, aryl, alkoxy, aryloxy, alkyl mercapto or dialkylaminomethyl radical, IN ADDITION TO WHICH AT LEAST ONE OF THE RADICALS R1, R2 or R4 represents a halogen atom, whilst the radical R3 can also represent a hydroxy group and, in the case of 3,5dihalogenphenols, exclusively represents a halogen atom, R represents OH, in addition to which R together with R1 can represent the radical - O- CH2 - O -CH2, the phenol oxygen atom standing for R, in which case X, R2, R3 and R4 independently of one another represent hydrogen, halogen or an alkyl radical and at least one of the radicals X or R3 and at least one of the radicals R2 or R4 represents a halogen atom.

    Abstract: The invention comprises dyestuffs of the formula where F is an organic dyestuff radical, R is alkylene or cycloalkylene, R2 is alkylene, R1 is -S-or where X is hydrogen, an araliphatic or cycloaliphatic substituent or an aliphatic radical which may form part of a heterocyclic nitrogen-containing 5 or 6 membered ring, Y is a substituent which, upon treatment with alkaline substances and/or heat, may be split off as a negative ion leaving R2 with a positive charge, and n is a whole number. Organic dyestuffs specified are those of the azo, anthraquinone, triphenylmethane, oxazine or azaporphin series, and values specified for Y are the sulphuric acid ester, phosphoric acid ester and sulphonyloxy groups and halogen atoms. The dyestuffs are made by reacting a dyestuff sulphonic acid chloride or carboxylic acid chloride with an amine containing the group -R-R1-R2-Y, by esterifying dyestuffs of the above general formula but wherein the group Y is hydroxyl, or by synthesising the dyestuffs from dyestuff intermediates already containing the group -R-R1-R2-Y, for example by diazotisation and coupling in the case of azo dyestuffs. The dyestuffs dye and print textile materials of natural or regenerated cellulose in conjunction with an alkali and heat treatment, and wool and silk from a weakly alkaline or neutral medium to give a variety of shades. Reference has been directed by the Comptroller to Specifications 835,819 and 868,741.
