摘要: 己二胺是生产尼龙66等产品的重要原料之一,在化纤、电子工业及高分子材料等产业中应用潜力巨大。综述了己二腈加氢法、己内酰胺法及己二醇氨化法等技术路线。在综合对比各技术路线优缺点的基础上,提出:国内己内酰胺产能“井喷”式增长使以己内酰胺为原料经氨化加氢制备己二胺路线产业化在经济上成为可能,但技术上仍需要解决由于反应-扩散耦合不协调导致产物选择性差、易结焦、催化剂单程寿命短等问题。

Abstract: Hexamethylenediamine is an important raw material for the production of nylon 66 and other products. It has great application potential in chemical fiber, electronic industry and polymer materials.This paper reviews the hydrogenation of adiponitrile, caprolactam and hexanediol amination, and the advantages and disadvantages of each technical route were analyzed. The "blowout" growth of domestic caprolactam production capacity makes it economically possible to industrialize the process of preparing hexanediamine from caprolactam via ammoniation and hydrogenation. However, technical bottlenecks such as poor product selectivity, susceptibility to coking and short catalyst lifetime due to the uncoordinated reaction-diffusion coupling still need to be solved.
