摘　　要：在硅 -磷 -硼三元体系的 T- 49固体磷酸催化剂基础上 ,开发了硅 -磷 -硼 - D四元体系的 T- 99固体磷酸催化剂。由于化合物 D的引入 ,催化剂综合性能大大改善 ,初活性和稳定性均得到提高 ,且齐聚物的选择性更高。 2 0 0 0 h齐聚反应稳定性试验显示 ,催化剂活性未下降 ,反应后催化剂形态基本上保持原状。T- 99催化剂适用于气态烯烃、尤其是丁烯的齐聚 ,也适用于丙烯Based on solid phosphoric acid catalyst (SPAC) T 49 composed of Si P B ternary system a new SPAC T 99 composed of Si P B D quaternary system was developed. Owing to the addition of compound D, the comprehensive performances of the catalyst have been greatly improved. Both the initial activity and stability of SPAC T 99 were enhanced, and the selectivity of oligomerization product was higher. The result of 2000 h catalyst stability test showed that its oligomerization activity was not declined and its morphology was almost unchenged. SPAC T 99 is suitable for oligomerization of gaseous olefins, especially that of butene, and for alkylation of benzene with propene as well.
