    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.

    Abstract: 4,6-diaminoresorcinol can be prepared in a plurality of steps in such a way thata) 1,3-dichlorobenzene is nitrated with a mixed acid of HNO.sub.3, H.sub.2 SO.sub.4 and SO.sub.3 at 0 to 40.degree. C. in anhydrous H.sub.2 SO.sub.4,b) the resulting 1,3-dichloro-4,6/2,4-dinitrobenzene isomeric mixture is first reacted with benzyl alcohol in the presence of a strong base at -15.degree. C. to +15.degree. C. and then at 20.degree. to 40.degree. C. to give the dibenzyloxy compound andc) the 1,3-dibenzyloxy-4,6-dinitrobenzene isomer arising in pure form in b) is converted to the 4,6-diaminoresorcinol by catalytic hydrogenation.
