Abstract: A process for dyeing textile materials, consisting of wool or nylon fibers, with anionic dyes in an aqueous liquor at up to 110 DEG C., wherein dyeing is commenced at a pH of from 7 to 9 and from 0.2 to 5 parts by weight, per 1,000 parts by weight of liquor, of an ester of a saturated C2-C4-carboxylic acid with an alcohol having a tertiary amino group in the 2-position are added at the dyeing temperature to act as a pH regulator.

Abstract: A process for the preparation of dyes which contain sulfonic acid groups and have a low electrolyte content, wherein an aqueous solution or suspension, which may or may not contain inorganic salts, of the dye containing sulfonic acid groups is (a) mixed with an amount, equivalent to the said dye, of a non-emulsifying, water-insoluble amine of a total of 12 to 40 carbon atoms, which forms, with the said dye, a salt which is sufficiently lipophilic for it to separate spontaneously from the aqueous phase, (b) the pH is brought to

Abstract: Alkanes substituted by chlorine atoms and/or sulfochloride groups are prepared by reacting alkanes with chlorine, with or without sulfur dioxide, in a particular throughput ratio, in a reaction chamber inclined to the horizontal, the starting materials being passed through the reaction chamber in co-current, from below. The substituted alkanes or paraffins obtainable by the process of the invention are pesticides, plasticizers, solvents and starting materials for the preparation of such products, as well as of fat liquors, detergents, lubricating oils, synthetic resins and slip agents.
