Abstract: A process for removing anionic compounds from water which is recycled in manufacturing processes, and from waste water, by adding (1) water-soluble products obtained by reacting an alkylating agent, having an aromatic substituent, with a cationic polyelectrolyte and (2) mineral adsorbents and/or a magnesium salt, aluminum salt or iron salt, with formation and flocculation of water-insoluble reaction products.

Abstract: A process for the manufacture of polyalkylenepolyamines by reacting a primary or secondary amine with a compound of the formula (I) where X is -Cl, -Br, or -OSO3H and R1 and R2 are H or saturated alkyl of 1 to 4 carbon atoms, and with at least the stoichiometric amount, based on the compound of the formula I, of an aqueous solution, of from 15 to 45 percent strength, of an alkali metal hydroxide or alkaline earth metal hydroxide, at from 60 DEG to 200 DEG C., cooling the reaction mixture to a temperature at which 2 aqueous phases form, and separating off the upper phase, containing polyalkylenepolyamnines. The rate of reaction can be increased by adding catalytic amounts of compounds which initiate the polymerization of alkyleneimines.

Abstract: Textiles are pre-treated in an aq. medium by alkaline boiling and/or bleaching, in presence of cpds. of formula (I), where R = 6-10C alkyl; X = H, Na, K or NR1R2R3R4; R1, R2, R3, R4 = H, 1-4C 1-4C alkyl or -CH2CH2OH. R = 7-9C alkyl, pref. 2,4,4-trimethylpentyl or 1-ethylpentyl. The amt. of (I) is 0.1-2 wt.%, w.r.t. the aq. medium.

Abstract: A process for dyeing textiles of cellulose fibres or mixtures of cellulose and synthetic fibres in aqueous mixtures after the extraction process in the presence of 0.1 to 10g/l of a compound of the formula (I) in which R = C6- to C18-alkyl and X = H, Na, K or NR R R R , where R , R , R and R = H, C1- to C4-alkyl or -CH''-CH''-OH. Light, uniform dyes are obtained and the coumpounds of formula (I) may be biologically removed from the waste water.
