摘要
在近似工业反应条件下(H_2/CO=1∶1,1.0MPa,70℃),应用加温加压原位核磁共振技术,考察了铑膦配合物催化剂HRh(CO)(PPh_3)_3-PPh_3体系的烯烃醛化反应。结果表明,在烯烃醛化反应条件下,反应液中存在羰基氢化铑中间配合物,并在~1H NMR获得了该配合物中Rh—H键的质子讯号。
Under the industrial reaotion conditions (H_2/CO=1:1, 1.0MPa, 70℃), the hydroformylation of olefin with rhodium-phosphine oomplex catalyst HRh(CO)(PPh_3)_3 is studied by using in situ NMR technique. The results show that the intermediate is hydride-rhodium carbonyl complex and the proton signal with a Rh—H bond in ~1H NMR has been observed.
