The invention relates to a method for continuously producing N-phosphono methyl glycine. The method comprises the following steps of: inputting reaction feed liquor into a reactor under the condition of oxidizing PMIDA into glyphosate to make an activated carbon catalyst suspend in the reaction feed liquor in the reactor; fully contacting the PMIDA with molecular oxygen; continuously oxidizing the PMIDA into the glyphosate under a selected reaction condition; and performing a PMIDA oxidizing reaction. The invention also relates to a device for continuously producing the N-phosphono methyl glycine. The device mainly comprises a power generator, a tubular reactor and a gas-liquid separator. The device is characterized in that: the power generator is connected with the bottom of the tubular reactor through a pipeline; the gas-liquid separator is connected with the top of the tubular reactor; the lower part of the tubular reactor is provided with an oxygen containing gas feed tube orificeand ...

The invention relates to a synthesis technology and device of iminodiacetate. The technology uses diethanol amine as a main raw material and comprises the following steps: dissolving the diethanol amine, mixing with a caustic soda solution and deionized water evenly to prepare a feed liquid the mass concentration of which is 10-30%, and transferring the feed liquid into a multistage tubular reactor loaded with a solid catalyst through a metering pump to perform catalytic dehydrogenation reaction to obtain iminodiacetate; and treating the gas generated through catalytic dehydrogenation and the tail gas separated from the discharged liquid to recycle hydrogen. The device comprises the multistage tubular reactor which is designed on the basis of a kinetic model of isothermal constant-pressure reaction, wherein the multistage tubular reactor is formed by connecting 2 to 5 tubular reactors in series; each reactor is formed by a plurality of tubes; the same amount of catalyst is evenly filled ...
