摘要: 我们曾对14个稀土氧化物作为高沸点醇、酸的多相酯化反应催化剂进行过探索,本文报导采用高温分解稀土与1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(HPMBP)配合物的方法可增大稀土氧化物的比表面,使其酯化催化活性有所提高。

Abstract: A method is proposed to increase the surface area of rare earth oxides from 1~2m2/g to 11~15m2/g by decomposing the complexes of rare earth with 1-phenyl-3-methyl-4-benzo-yl-pyrazol-5-one.The catalytic activities of so-treated rare earth oxides.i.e.Ho2O3,Tm2O3Gd2O3 and Lu2O3 in esterification were found to be improved.

Key words: rare earth oxide, catalytic activity, esterification, phenyl methyl benzoyl pyrazolone
