Abstract: Marked mineral oils are marked with basic dyestuffs (I) contg. at least 2 (substd) amino gps. which undergo a bathochromic shift in the absorption max. and increase in extinction on addn. of a protonic acid and opt. a Zn, Al or Sn halide. (I) are triarylmethane, xanthene or azo dyestuffs.

Abstract: Finely divided, gel-like crosslinked polymers are prepared by a continuous method in which a monomer mixture which contains, per 100 parts by weight of acrylic acid or methacrylic acid, from 50 to 100 mol % of which in each case are neutralized, acrylamide, methacrylamide or N-vinylpyrrolidone, from 0 to 30 parts by weight of other water-soluble monoethylenically unsaturated monomers and from 0 to 20 parts by weight of water-insoluble monoethylenically unsaturated monomers is copolymerized with from 0.01 to 5 parts by weight of a crosslinking agent, in 20-65% strength by weight aqueous solution in the presence of an initiator at from 45 DEG to 95 DEG C. in a single-screw cylindrical mixer whose stirrer shaft possesses disk segments which have, at the outer end, mixing bars which are arranged in a manner such that the substances fed in at the entrance of the mixer are conveyed in the axial direction to the exit of the mixer, the aqueous monomer solution in the mixer is polymerized under from 100 to 800 mbar, and some of the water is removed during the polymerization, so that a crumb-like gel having a solids content of from 30 to 70% by weight is discharged.

Abstract: In an aqueous acidic plating bath for the electrolytic deposition of zinc, which contains conventional conductive salts, brighteners and surfactants, one of the surfactants is a surfactant of the formula I where R1 is C4-C20-alkyl, R2 is identical to R1 or is hydrogen, X and Y are each a radical -SO3H, where the hydrogen atom can be replaced by an alkali metal or alkaline earth metal atom or by one equivalent of zinc and n is an integer from 5 to 50.

Abstract: Aqueous emulsion containing 30- to 70-fold ethoxylated, optionally hydrogenated caster oil as emulsifier and/or at least one surfactant of the formula in which R denotes a C8- to C20-alkyl radical, C4- to C12-alkylphenyl radical or an aliphatically saturated or unsaturated C8- to C20-acyl radical, A stands for an ethylene oxide and/or propylene oxide unit and n for 3 to 60, and its use as a high-quality brightener in acidic zinc electroplating baths.

Abstract: Azo dyes of the formula in which R1, R2 and R3 independently denote hydrogen, C1-C4-alkyl or C1-C4-alkoxy, R4 denotes C1-C6-alkyl and R5 denotes C2-C8-alkyl which is substituted by hydroxy and may be interrupted by 1, 2 or 3 oxygen atoms, provided that the total number of carbon atoms in the radicals R4 and R5 is at least 5, mineral oils containing one or more of said novel dyes and the use of said dyes for marking mineral oils.
