IMMOBILIZED CATALYST FOR ISOMERIZATION REACTION

摘要

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 (R1 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 (R2 is lower alkyl group, R3 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 200-300 deg.C to make it possible to regenerate and reuse.
