摘　　要：研究了己内酰胺钠的制备及用己内酰胺钠作催化剂合成MC尼龙的方法,并与氢氧化钠作催化剂合成的MC尼龙作了性能对比。结果表明,使用己内酰胺钠催化剂合成的MC尼龙的转化率、吸水率、力学性能基本保持不变,但加入己内酰胺钠后可不抽真空,因此可以大批量生产,提高生产效率。The synthetic method of sodium caprolactam is presented. The technological process of catalytic synthesis of MC nylon with sodium caprolactam instead of the conventionally used catalyst sodium hydroxide is researched. The properties of sodium caprolactam catalyzed MC nylon are compared to that of sodium hydroxide catalyzed MC nylon. Results show that the conversion rate, the water absorption rate and the mechanical properties of the MC nylon are close to the sodium hydroxide catalyzed MC nylon. In the catalytic synthesis of MC nylon with sodium caprolactam, vacuum pumping is not necessary after adding catalyzer. The productivity can be raised and mass production is available.
