    Abstract: Products which have been obtained by reacting an acid of the formula I I where R1 and R2 are hydrogen, fluorine, chlorine, bromine or alkyl or alkoxy of 1 to 4 carbon atoms, but the sum of the carbon atoms of R1 and R2 is not greater than 7 and preferably not greater than 3, A is a benzene, naphthalene or anthracene radical or a biphenyl structure, such as a diphenyl, diphenylmethane, diphenyl ether, diphenyl sulfide, diphenyl sulfoxide or diphenyl sulfone radical, R3 is hydrogen, alkyl of not more than 4 carbon atoms, beta -cyanoethyl or hydroxyalkyl of 2 to 4 carbon atoms, R4 is hydrogen, fluorine, chlorine, bromine, alkyl or alkoxy of 1 to 4 carbon atoms, hydroxyl or carboxyl and X is -SO2- or -CO-, with an amine of the formula II II where R5 and R6 are hydrogen, C1-C4-alkyl, C2-C4-hydroxyalkyl and/or R7 and R8 being hydrogen, C1-C4-alkyl or C2-C4-hydroxyalkyl and n being an integer from 2 to 4, in the ratio, expressed in terms of equivalents, of from 1:1 to 1:4, and corrosion inhibitors which contain these products, with or without the admixture of an alkanolamine/boric acid reaction product.

    Abstract: High purity products are obtained and formation of polyglycols is suppressed by reacting OH-contg. aromatic cpds. or carboxylic acids with 1,2-epoxides (e.g. ethylene oxide) in the presence of a betaine-type salt of an oxidic sulphur acid having the general formula: (in which X is N, S or P; R1, R2 and R3 (the latter is absent when X is S) denote the same or different, opt. substd. alkyls, aryls, hydroxyalkyls or aralkyls; R is a divalent, opt. substd. 1-10C alkylene gp.; and Y is a sulphito, sulphato, sulphonato, thionamato or sulphamato gp.; R1 and R2 may form a heterocyclic ring with N). The products are used as textile auxiliary agents; printing paste components; starting materials for polyesters; comonomers for vinyl polymerisation.

    Abstract: The production of ammonium betaines by reaction of adducts of an oxide of sulfur and an amine with an aziridine, and the new ammonium betaines themselves. The new compounds obtainable according to the process of the invention are surfactants, particularly detergents and assistants in the textile field, softeners, washing aftertreatment agents, germicides, and valuable starting materials for the production of detergents, cleaning agents, detergents, wetting agents, textile assistants, dishwashing agents, shampoos, emulsifiers, dispersing agents, flotation aids, softeners, disinfectants and thickeners.

    Abstract: Prepn. of 2-(benzylidene or naphthylidene) acylacetic or malonic acid esters or amides of formula Ar-CH=C(COR )(COR ) (I) involves reacting an aromatic aldehyde of formula ArCHO (II) with an active methylene cpd. of formula CH2(COR )(COR ) (III). In the formulae, Ar = phenyl or naphthyl (both opt. substd. by 1-3 or 1-4C alkyl, 1-4C alkoxy and OH); R = 1-8C alkoxy, phenoxy, benzyloxy or -NR R ; R ,R = H or 1-6C alkyl; R = 1-4C alkyl, phenyl, benzyl or as R . The novelty is that the reaction mixt., at the end of the reaction, is washed with aq. alkali metal (hydrogen) sulphite soln. to remove residual, unconverted (II). Pref. the organic solvent in the organic phase obtd. after the (bi)sulphite wash is distilled off to give a technical prod. contg. (I). The use of this technical prod. as brightener is claimed. Preferably, Ar = phenyl (opt. substd. by 1 or 2 of Me, Et, OMe and OEt); R = 1-8C alkoxy; R = 1-4C alkyl or 1-6C alkoxy. Esp. Ar = Ph, R = OMe or OEt, and R = Me, OMe or OEt.
