Yield:109-84-2 98%
Reaction Conditions:
with hydrazine hydrate at 0 - 60; under 7500.75 - 18751.9 Torr;Inert atmosphere;
Steps:
1
Ethylene oxide is added to the liquefied gas storage tank in VO1, a nitrogen-pressurized to 1.0 ~ 1.5MPa, 80% hydrazine hydrate was added to tank VO2,The molar ratio of hydrazine hydrate to ethylene oxide was controlled to 8: 1, Respectively by the feed chestnut PO1, respectively, by the feed pump, feed pump PO2 feed, total feed flow rate was 2.0L / h, the micro-mixer temperature was 40 °C, cracking reactor temperature was 60 °C, micro heat exchanger temperature set 0 ~ 10 °C, back pressure valve back pressure 1.5 ~ 2.5MPa, two liquid feed stocks into the mixing CPMM-R300 micromixer and further reacted in the cracking reactor, the reaction liquid through a heat exchanger to cool the micro proceeds to receiving reservoir tank, distillation under reduced pressure to remove most of the water and the excess hydrazine hydrate, to give a colorless oily liquid 2-hydroxyethyl hydrazine, detecting the GC purity 89.5%, yield 98%; washed with water and the whole microreactor system.
