烯烃羰化制醇原位红外光谱表征

IN SITU IR CHARACTERIZATION OF CATALYST FOR HYDROFORMYLATION AND HYDROGENATION OF OLEFIN ON ALCOHOL OXOSYNTHESIS

本文以Rh_2(AcO)_4和Rh_6(CO)_(16)为催化剂。在高压釜中,控制在最佳反应条件下,进行庚烯氢甲酰化和加氢制醇反应。利用红外光谱表征方法,考察了Rh/PBu_3/EtOH催化体系中活性物种的生成过程以及在催化反应中随着反应进行,醛的形成及醛由于加氢成醇而逐渐消失的过程,测得的原位红外光谱与空气中测定的红外光谱进行了比较。

In this paper, Rh2( AcO)4 and Rh6(CO)16 were used as catalyst for hyclroformy lation and hydrogenation of heptcne to form octanol in a higb pressure reaction autoclave under favourable conditions.A active species was studied by In Situ IR in the Rh/FBu3/EtOH catalysis system, and in which aldehyde appear and disappear to form octanol in the end. The In Situ IR spectra is different from that was determined in air.
