中文摘要:

      将原位红外光谱表征方法用于探测Rh-PBu3-EtOH体系中的庚烯氢甲酰化制辛醇的反应历程及活性物种的形成过程和以Al₂O₃为载体的Rh-PPh3催化剂活性物种的活化及氧化失活过程的研究.

英文摘要:

      In situ IR spectra were used to monitor the catalysis of hydroformylation and hydrogenation of heptene to octanol in Rh-PBu₃-EtOH system in which active species was formed, and the active species anchored on Al₂O₃ was oxidated by oxygen in air and became lessa ctive.
