Synthesis process of hexamethylenediamine piperidine

The invention relates to a synthesis process of hexamethylenediamine piperidine. The process comprises the steps of: carrying out heating dehydration reaction on 2, 2, 6, 6-tetramethyl-4-piperidone and 1, 6-hexamethylenediamine in a negative pressure environment until no water is removed from the system, and adding a water removing agent to separate the residual water from the liquid system so asto obtain an intermediate Schiff base; introducing hydrogen into the obtained Schiff base in the presence of a catalyst for hydrogenation reaction to obtain hydrogenation liquid; and filtering out thecatalyst from the hydrogenation liquid, rectifying the filtrate, and carrying out crystallization-desolvation to obtain the hexamethylenediamine piperidine finished product. According to the method,a small amount of residual water is removed by using the water removal agent, so that the Schiff base is prevented from being decomposed in the presence of trace water, the purity of the Schiff base is improved, the yield of hexamethylenediamine piperidine is increased, and few solid wastes are generated; according to the method, negative pressure reaction and crystallization treatment are innovatively adopted, so that the quality of hexamethylenediamine piperidine is high, the solvent can be continuously recycled and reused, and no organic waste liquid is generated.
