    摘要: 1,2,4-triazole is obtained by cyclization of N,N'-diformylhydrazine with ammonia in the presence of formamide. The amount of ammonia required is either formed in situ from thermally decomposable ammonium salts, or supplied by feeding in gaseous ammonia. Simultaneously, the water of reaction is constantly distilled off from the system.

    摘要: A large number of customary processes for separating amino acids fails when very polar hydrophilic amino acids with isoelectric points (IEP) which are close to one another are to be fractionated. Mixtures of L-glutamic acid (IEP=3.24) and L-phosphinothricin (IEP=2.6) produced by enzymatic transaminations of the corresponding .alpha.-keto acid have been difficult to separate to date. The invention relates to a process for separating L-phosphinothricin and L-glutamic acid, which comprises carrying out the separation as liquid/liquid extraction with two non-miscible aqueous phases as phase system, where the phase former contained in the phase system is a combination of at least two different water-soluble polymers or of at least one water-soluble salt and one water-soluble polymer, and the extraction is carried out by multistage countercurrent partition on the van Dijck principle.
