Reaction Conditions:
with hydrazine hydrate in methanol;water at 75; for 0.000833333 h;Solvent;
Steps:
1 Preparation of carbohydrazide
Dissolving dimethyl carbonate in methanol, Made into a 3mol/L solution, It was injected into the microchannel reactor or the pipeline reactor through a metering pump at a flow rate of 30 ml/min. 80% by mass of aqueous hydrazine hydrate solution was passed through another metering pump at 11.26 ml/ The flow rate of min is injected into the microchannel reactor or the pipeline reactor, React at 75 ° C for 3 seconds, Flow out of the microchannel reactor or pipeline reactor, Collecting reaction materials, Obtaining a white crystalline product, Yield 99%, 99.9%, The monoterpene content is 0.01%.
