| titleOfInvention | Method for obtaining thiocarbohydrazide |
| abstract | This invention relates to hydrazides, in particular, to the preparation of thio-carbohydrazide, which is used in the synthesis of polymers, dyes, and ion exchange resins, in the photograph. The goal is to increase the safety of the process. The reactions are obtained by reacting sodium diethyldithiocarbamate with hydrazine hydrate in the presence of hydrazine dihydrochloride. and water at a mass ratio of 1: (0.7-0.8): (0.3-0.4) :( 0.1-1, /) at 80-95 ° C. "The process is carried out with a return the mother liquor in the reaction Yield 91% about 1 table, |
