摘　　要：应用化工流程模拟软件Aspen plus对己内酰胺水解聚合系统进行模拟。模拟计算了聚合物的相对分子质量及可萃取物含量随引发剂用量、进料流量、各聚合阶段温度的变化。结果表明:增加引发剂用量可以缩短聚合反应时间,但会降低聚合物的质量,选择引发剂质量分数0.013%为宜。随着进料流量的增加,聚合物相对分子质量减小且低于设计值,可萃取物含量增加且高于设计值;采用较低的聚合前段温度,可减少能耗,降低后段温度,可萃取物质量分数可降低至8%以下。A caprolactam hydrolysis polymerization system was simulated with Aspen plus chemical engineering simulation sottware. The changes of the relative molecular mass of polymers and extractable contents with initiator amount, feeding rate and temperatures of different polymerization stages were simulated. The results showed that the increase of initiator amount could shorten the polymerization time, but impact the polymer quality. The initiator amount should rationally be 0.013%. The relative molecular mass of polymers was decreased to a degree lower than the designed value and the extractables content was increased to a degree higher than the designed value as the feeding rate was increased. The energy consumption can be reduced by decreasing the temperature of the early polymerization stage, and the mass fraction of the extractables can be lower than 8% by decreasing the temperature of the later polymerization stage.
