    摘要： There are produced peptides by asymmetrical hydrogenation of dehydropeptides of the general formula ##STR1## in which n is a whole number from 1 to 4, R.sub.1 and R.sub.2 are the same or different, and are hydrogen, a straight or branched chain alkyl group with 1 to 10 carbon atoms, or such a group substituted with a carboxyl group, a phenyl group which is unsubstituted or substituted in the 3 or 4 position or in both the 3 and 4 positions by a hydroxyl, alkoxy, or acyloxy group or an indolyl group which is unsubstituted or substituted in the 6 position by fluorine or chlorine or an indolyl group substituted by a methyl group. R.sub.3 is hydrogen, an alkali metal, or a lower alkyl group with 1 to 4 carbon atoms, R.sub.4 is hydrogen, an acetyl group or a chloroacetyl group and R.sub.5 is hydrogen or a straight or branched chain alkyl group having 1 to 4 carbon atoms with the proviso that when n is 2, 3, or 4, the individual groups R.sub.5 are the same or different, in the presence of chiral rhodium-complexes.

    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:

    摘要翻译： 本发明涉及三聚巯基三嗪的钠盐水溶液，其摩尔饱和浓度在0℃至40℃高于三巯基-s-三嗪三钠盐（TMT-Na 3）的饱和浓度。 三聚巯基-s-三嗪的多于两个但少于三个的氢原子被钠离子代替。 除了少量TMT-Na3之外，溶液优选含有三巯基-s-三嗪二钠盐（TMT-Na2）。 令人惊讶的是，TMT-Na2的水溶性大于TMT-Na3的水溶性。 该溶液代表用于分离重金属的活性物质三巯基-s-三嗪（TMT-H3）的合适供应形式。该制备通过使TMT-Na 3与TMT-H3以摩尔比1： 大于0-小于0.5，特别是在水溶液中为1：0.1至1：<0.5。

    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.
