    • PURPOSE: To obtain a catalyst whose high catalytic activity is maintained even by repeated uses, by adsorbing polyaminsulfon shown by a formula to a solid inorg. carrier, adsorbing and immobilizing deuteroporphyrin IX CO divalent complex shown by a formula thereto.
      CONSTITUTION: Polyaminsulfon consisting of repeated units shown by the formula I (R
      1 is lower alkyl group, X is halogen atom) is adsorbed to a solid inorg. carrier such as activated alumina. Deuteroporphyrin IX CO divalent complex shown by the formula II (R
      2 is lower alkyl group, R
      3 is hydroxycarbonyl lower alkyl group) is adsorbed and immobilized to the modified inorg. carrier to obtain an immobilized catalyst for isomerization reaction from quadricyclanes to norbornadienes. The catalyst has not only high reactivity at the isomerization reaction, but also its catalytic activity is maintained at the high level even by repeated use. The catalytic activity is recovered to almost 100% by heat treatment at 200W300°C to make it possible to regenerate and reuse.

    • 目的:为了获得甚至通过重复使用保持其高催化活性的催化剂,通过将式中所示的聚胺砜吸附到固体中。 载体,吸附并固定其配方所示的氘卟啉IXCO二价络合物。 构成:由式I所示的重复单元(R1是低级烷基,X是卤素原子)组成的聚氨基磺酸被吸附在固体上。 载体如活性氧化铝。 由式II(R2是低级烷基,R3是羟基羰基低级烷基)表示的氘卟啉IX CO二价络合物被吸附并固定在修饰的化合物上。 载体以获得用于从四环素到降冰片二烯的异构化反应的固定化催化剂。 该催化剂在异构化反应中不仅具有高反应性,而且即使重复使用,其催化活性也保持在高水平。 通过在200-300摄氏度的热处理将催化活性回收到几乎100%,使其可以再生和再利用。
