    Abstract: PROBLEM TO BE SOLVED: To easily obtain a novel chemical agent for marking well penetrating into a wood and to generate marked color reaction by an extremely small amt. of the marking substance to enable visual observation, by treating the wood with arylamine represented by a specific formula. SOLUTION: In a wood marking method, wood is treated with arylamine represented by formula I, wherein Ar is a group represented by formula II, R and R are mutually unrelated hydrogen, a C1 -C18 alkyl group which may be substituted, may be interrupted in a form of an ether functional group by 1-3 oxygen atoms or interrupted by 1-3 non-adjacent C1 -C4 alkylimino groups, C5 -C7 cycloalkyl, C3 -C18 alkenyl or phenyl which may be substituted, or R and R are a 5- or 6-membered saturated heterocylic group together with a nitrogen atom.

    Abstract: Azo dyes of the formula in which R and R are each hydrogen, C1-C4-alkyl or C1-C4-alkoxy, R is hydrogen or C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, R is C1-C8-alkyl which is optionally substituted by hydroxyl and can be interrupted by 1 to 3 oxygen atoms, and X is cyano or optionally substituted C1-C8-alkoxycarbonyl, with the proviso that at least one hydroxyalkyl radical is present in the molecule, mineral oils containing one or more of the novel dyes, and the use of the novel dyes for labelling mineral oils.

    Abstract: Bead polymers are prepared by reverse suspension polymerization by a process in which an aqueous solution of water-soluble ethylenically unsaturated monomers are polymerized in an aliphatic hydrocarbon using an inorganic suspending agent based on a modified finely divided mineral and, in addition, from 0.1 to 5% by weight, based on the monomers used, of a nonionic surfactant, in the presence of a polymerization initiator, with the formation of a water-in-oil polymer suspension.

    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: Foam is controlled in the sugar industry and yeast industry by a process in which oxyalkylation products of the formula I R-O-(X1)n-(X2)m-(X3)p-Z where R is alkyl of 6 to 22 carbon atoms or alkylphenyl where alkyl is of 6 to 12 carbon atoms, X1 and X3 are ethylene oxide units, n and p are each from 0 to 15 and the sum of n and p is not less than 2, the groups X2 are propylene oxide and/or butylene oxide units, m is from 0 to 15 and Z is straight-chain or branched alkyl of 1 to 4 carbon atoms, allyl or benzyl, having a turbidity point of
