Abstract: N-(2-Hydroxyethyl)piperazine of the formula I is prepared by reaction of triethanolamine of the formula II with ammonia in the presence of hydrogen at temperatures from 100 to 500 DEG C and pressures from 10 to 500 bar on heterogeneous catalysts, employing heterogeneous catalysts having an active mass containing 20 to 85% by weight of ZrO2 and/or Al2O3, 1 to 30% by weight of oxygen-containing compounds of copper, calculated as CuO, 1 to 60% by weight of oxygen-containing compounds of cobalt calculated as CoO and/or oxygen-containing compounds of nickel, calculated as NiO and/or oxygen-containing compounds of molybdenum, calculated as MoO3.

Abstract: Paper fibres are bonded in absence of metallic salts at pH 5-9 pref. 6-8 using anionic polymer dispersions by polymsn. with a hydrophobic monomer in aq. medium in presence of emulsifiers contng. COOH gps., where the dispersions contain particles of mean size 200 nm and having Tg. 70 degrees C. Monomers are e.g. (meth)acrylic acid esters with >3C alcohols, or vinyl aromatic cpds. Emulsifiers are salts of (iso) fatty acids or resinic acids and their hydrogenation/disproportionation products or ethylene or diene reacted with maleic acid derivs. The process prevents growth of algae and deposits of adhesive and foaming. Corrosion is also reduced because the soln. is at near neutral pH in absence of salts.

Abstract: Water-soluble, nitrogen-containing condensates are prepared by reacting a cross-linking agent, obtained by (a) condensing 1 mole of a dicarboxylic acid of 4 to 10 carbon atoms with from 1 to 2 moles of a polyalkylenepolyamine, having 3-10 basic nitrogen atoms in the molecule, to give a polyamidoamine and (b) reacting the polyamidoamine with epichlorohydrin and/or dichlorohydrin in aqueous solution at a pH of from 4.5 to 8.5 and at below 100 DEG C., from 1 to 130 parts by weight of epichlorohydrin and/or dichlorohydrin being employed per 100 parts by weight of the polyamidoamine from (a), with ammonia, a primary amine, a polyamine containing 2 to 4 N atoms, a polyether-amine or a polyamidoamine in aqueous solution at below 100 DEG C. The condensates are used as retention aids, flocculants and drainage aids in papermaking.
