ABSTRACT:
Alkylhydrazine salts are prepared on an industrial scale and with good results by reacting together hydrazine, an alkene and a strong protonic acid in the presence of water, hydrazine and the protonic acid being introduced, the alkene being added, the liquid and gaseous phases present in the reaction vessel being intensively mixed together at 75.degree. to 150.degree. C., then the reaction mixture being cooled to temperatures below 60.degree. C., the precipitated alkylhydrazine salt being separated off, hydrazine and strong protonic acid being again added to the mother liquor, then alkene being added again and the next reaction cycle being thus carried out.
