Continuous hydrazide preparation method

The invention relates to a continuous hydrazide preparation method. The preparation method includes: in a micro-channel reactor or a pipeline reactor, subjecting esters, anhydrides or acyl chloride tocontinuous reaction with hydrazine or solution of hydrazine under a solvent-free condition or in a solvent to prepare a hydrazide compound. The preparation method is simple, short in technical process, less in waste gas, wastewater and industrial residues, beneficial to environmental production and suitable for industrial production. The adopted reactor is short in reaction time, high in safety and capable of realizing continuous production. The adopted reactor is high in workshop space utilization rate, and large-scale production can be realized. By adoption of the preparation method, solvent recycling can be realized, and production cost is reduced; in addition, high raw material conversion rate, high quality stability and high purity are realized.
