Abstract

Variation of the nature of the components of the catalytic systems comprising a catalyst [Pd/C, Pd(α,α-bipy)Cl2, RhCl3] and a cocatalyst (FeSO4, CuSO4), as well as a coreductant (H2, CO), allows exerting some control over the selectivity of the process of propane oxidation with oxygen. In particular, the yield of carbonyl compounds such as acetone and propanal in the presence of the Pd/C–FeSO4–H2catalytic system reached 90%, and that of propyl esters in the presence of RhCl3–CuSO4–CO catalytic system was 64.5%. These differences are supposedly attributable to the changes in the process mechanism depending on the composition of the catalytic systems.

丙烷的氧化:催化剂、助催化剂和助剂性质的影响

摘要

包含催化剂 [Pd/C, Pd(α,α-bipy)Cl 2 , RhCl 3 ] 和助催化剂 (FeSO 4 , CuSO 4 ) 以及助催化剂( H 2 , CO) 允许对丙烷与氧气氧化的过程的选择性进行一些控制。特别是在Pd/C-FeSO 4 -H 2催化体系存在下丙酮和丙醛等羰基化合物的产率达到了90%,在RhCl 3 -CuSO 4存在下丙酯的产率达到了90%-CO催化体系为64.5%。据推测,这些差异可归因于取决于催化体系组成的过程机制的变化。
