N,N`-BIS-((1-FORMAMIDO-2,2,2-TRIKLOR)ETYL)-PIGPERAZIN FOR ANVENDELSE SOM FUNGICID VED BEKJEMPELSE AV FYTOPATOGENE SOPPER |
摘要 |
Isomers and isomeric mixtures of N,N'-bis-(1-formamido-2,2,2-trichloro-ethyl)-piperazine, and a method of isolating such isomers and isomeric mixtures by extracting conventionally prepared N,N'-bis-[(1-formamido-2,2,2-trichloro)-ethyl]-piperazine, which contains about 50% by weight of the more soluble isomer, with a solvent or solvent mixture in which the solubility ratio of the more soluble isomer to the less soluble isomer is at least about 3:2, isolating the extracted substance and optionally further purifying the isolated substance by conventional purification procedures, such as recrystallization or chromatography; the isomers and isomeric mixtures thus obtained are useful as agricultural fungicides. |
