摘要: 现有稀土异戊橡胶催化剂工业技术主要有俄罗斯的氯化稀土催化剂技术和中国的羧酸稀土催化剂技术,其中羧酸稀土催化剂技术又包括非均相羧酸稀土催化剂技术和均相羧酸稀土催化剂技术。近10年来,3种技术都在工业装置上得到了成功应用与发展,各有优缺点,然均相羧酸稀土催化剂技术因加入量容易控制、活性中心稳定、产品顺-1,4-结构含量较高而更具综合优势。未来的发展方向应是更高活性和更高顺-1,4-结构选择性的均相羧酸稀土催化剂工业技术。

Abstract: The present catalyst technologies for production of Nd-catalyzed isoprene rubber include Russia′s rare earth chloride technology and Chinas rare earth carboxylate technology. China′s rare earth carboxylate technologies further consist of heterogeneous technology and homogeneous technology. During last 10 years or so, the three technologies all have been practiced successfully and well developed in the industrial plants. Despite of their advantages and disadvantages, the homogeneous catalyst technology of rare earth carboxylate shows comprehensive superiority for its easy dosing, stable activity and higher selectivity of cis-1,4-polyisoprene. The future trend of development should be the homogeneous catalyst technologies of rare earth carboxylate with both much higher activity and selectivity in cis-1,4-polyisoprene.

Key words: Ndcatalyzed isoprene rubber; catalyst; industrial technology
