Device of continuous production N - ethoxy oxalyl - L - alanine ethyl ester

The utility model discloses a continuous production N the ethoxy oxalyl L the device of alanine ethyl ester to benzene is the desiccant, dissolves in the batching cauldron and prepares the mixed liquid of raw materials, carry the pre -heater to preheat the mixed liquid of preparing of raw materials, through the reboiler with material heating to 70 DEG C to 85 DEG C consecutive reaction, input benzene in the back reaction rectifying column, regard as the desiccant to eliminate the moisture that the reaction produced in succession benzene, the water of production will react to is evaporated from the top of the tower of reaction rectifying column to the form of benzene, ethanol, water ternary azeotropic mixture, after the condenser condensation, and the automatic phase separating of rethread coalescence phase splitter, the upper strata contains a small amount of water, ethanol after the phase separating the benzene reaction rectifying column that flows back back mutually, the lower floor goes to follow -up dehyd
