Abstract: Preparation of chrome tanning solutions having a basicity of 33 to 50%, by reduction of solutions of dichromate in sulphuric acid with methanol in the presence of heat, followed if necessary by completion of the reduction with formic acid and/or sulphite. The solutions thus obtained need only to be diluted with water for use for tanning, without sodium sulphate having to be removed beforehand and without neutralisation having to be carried out during tanning. They can also be processed to give pulverulent tanning materials without problems by spray drying.

Abstract: Polyester fibres or their mixts. with other fibres are dyed at over 130 degrees C, with addn. to the dye bath of at least one phthalate diester of a 6-20C aliphatic or araliphatic alcohol in emulsion form. Deposition of polyester oligomer as a powder on the fibre or on the equipment walls is prevented without reducing stability of the dye bath. In partic. ester of 8-15 C alcohols are used, in amount of 0.05-0.4 (0.1-0.3)% of the dye bath. They are emulsified using mixts. of anionic and non-ionic surfactants. The former is pref. an alkali or NH4 salt of a sulphate semi-ester of a 12-18 C alcohol or alkyl phenol reacted with 2-4 mols. ethylene oxide. The latter is pref. a 12-18 C fatty acid reacted with 5-50 mols. ethylene oxide (esp. on oleic acid deriv.), or castor oil reacted with 5-20 mols ethylene oxide per OH gp.

Abstract: A lubricant for molding chlorine-containing thermoplastics, which contains ethylene/acrylic acid or ethylene/maleic acid copolymers esterified, in a molar ratio of carboxyl groups to alcoholic hydroxyl groups of from 1:0.2 to 1:1, with C1-C20-aliphatic alcohols which may or may not contain ether groups, the copolymers, prior to esterification, having a mean molecular weight of from 500 to 10,000 and containing from 2 to 15% by weight of acrylic acid or from 1 to 8% by weight of maleic acid as copolymerized units, the percentages being based on copolymer.

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.
