    摘要: The disodium salt of trimercapto-s-triazine hexahydrate (TMT-Na.sub.2.6H.sub.2 O) which has a considerably higher water solubility than previously known TMT sodium salts. It is used for separating heavy metals from aqueous phase, especially from waste water.TMT-Na.sub.2.6H.sub.2 O is prepared by reacting TMT-Na.sub.3 .9H.sub.2 O, available from cyanuric chloride, with trimercapto-s-triazine (TMT-Ha.sub.3) in a molar ratio of 2-2.1 to 1 in aqueous medium with subsequent crystallization of the TMT-Na.sub.2 .6H.sub.2 O.

    摘要: The invention relates to aqueous solutions of sodium salts of trimercapto-s-triazine whose molar saturation concentration at 0.degree. C. to 40.degree. C. is above the saturation concentration of trimercapto-s-triazine trisodium salt (TMT-Na.sub.3). More than two but less than three hydrogen atoms of the trimercapto-s-triazine are replaced by sodium ions. The solutions preferably contain trimercapto-s-triazine disodium salt (TMT-Na.sub.2) in addition to a little TMT-Na.sub.3. Surprisingly, the water solubility of TMT-Na.sub.2 is greater than that of TMT-Na.sub.3. The solutions represent a suitable supply form for the active substance trimercapto-s-triazine (TMT-H.sub.3) used in the separation of heavy metals The preparation takes place by means of reacting TMT-Na.sub.3 with TMT-H.sub.3 in a molar ratio of 1:greater than 0-less than 0.5, especially 1:0.1 to 1:

    摘要: A process for producing 3-aminomethyl-3,5,5-trimethylcyclohexyl amine (isophorone diamine) from isophorone nitrile. Isophorone nitrile is iminated in a first stage and then the reaction mixture is subjected to aminating hydrogenation in a second stage in the presence of a fixed bed hydrogenation catalyst based on Raney cobalt. The fixed bed hydrogenation catalyst is produced in a special manner by mixing a powdery Co--containing Raney alloy with powdery cobalt, sintering the powdery mixture to shaped moldings and then activating by leaching with alkali hydroxide solution. The yield and/or space-time yield in isophorone diamine production can be increased.
