乙醇羰化反应负载型催化剂的研究

本文由七种负载型催化剂中选出两种比较好的乙醇羰化催化剂,研究了影响反应转化率和选择性的因素,考察了活性组份的价态和载体的酸性。此外,还对催化剂进行了能量色散X射线分析。从其结果看,谱图上只有活性中心铑的谱峰而没有氯的谱峰,说明铑是以离子形式进入载体,而不是以化合物形式被吸附于载体上。

STUDY ON SUPPORTED CATALYSTS FOR CARBONYLATION OF ETHANOL

Two better ones out of seven supported catalysts were selected for carbonylation of ethyl alcohol. Factors effecting the conversion and selectivity for the reaction have been studied and the valence state of active species and the acidity of carrier have also been examined.Energy dispersion X-Ray analysis was used to determine active components in the catalysts. The analytical result shows only the line for Rh~( 3) and no line for Cl~-. This suggests that rhodium ions are incorporated into the bulb of the carrier and not adsorbed as Rh compounds on the surface.
