Reaction Conditions:
with 5% active carbon-supported ruthenium;hydrogen at 30; under 3750.38 Torr; for 4 h;Temperature;Pressure;Reagent/catalyst;
Steps:
1-4; 1-3 Example 4
A synthesis process of p-chlorophenylhydrazine hydrochloride includes the following steps:
(2) mixing substance A with a 5% ruthenium-carbon catalyst, the mass ratio of catalyst to p-chloroaniline is 0.1: 1, and nitrogen was substituted 3 times. Pass in hydrogen for 3 times and pressurize to 0.5MPa under hydrogen conditions. Heating to 30 °C, holding time 4h, filtering, it is obtained by drying at 105 °C. After testing, the yield of p-chlorophenylhydrazine hydrochloride was 98.2%, and the purity was 99.7%.
