Micro-reaction system and method for continuously preparing 2-amino-1,3-diol compounds

The invention belongs to the technical field of pharmaceutical engineering, and particularly relates to a micro-reaction system and method for continuously preparing 2-amino-1,3-diol compounds. The micro-reaction system comprises a micro-mixer and a micro-channel reactor which communicate with each other in sequence; the micro-mixer is used for mixing a solution of a raw material 2-nitro-1,3-diol compound with hydrogen; and the micro-channel reactor is used for continuous reaction of the mixture. The method comprises the following steps: packing a palladium catalyst in the microchannel reactor, dissolving a 2-nitro-1,3-diol compound in an organic solvent, conveying the dissolved 2-nitro-1,3-diol compound and hydrogen into the microchannel reactor at the same time, and carrying out a continuous catalytic hydrogenation reaction to obtain the corresponding 2-amino-1, 3-diol compound. According to the method, the reaction time is only several minutes, the yield of the product 2-amino-1,3-diol compound is larger than 99%, the technological process is continuous, the automation degree is high, the space time yield is high, operation is easy and convenient, the step of separating reaction liquid from a catalyst is not needed, cost is low, and the method is environmentally friendly, safe and easy for industrial production.
