摘　　要：将金属铑粉与复合溶剂R101混合,回流2 h,使金属铑溶解,再与KI反应0.5 h,制备催化剂碘化铑,用于催化醋酸甲酯羰基化合成醋酐醋酸的反应。结果表明,本方法制备的碘化铑纯度高,催化性能与标准物质相当,而且溶剂可回收再利用,溶解条件缓和,便于工业化生产。The metal rhodium powder composite solvents mixed and refluxed the metal rhodium dissolved, and reacted with KI 0.5 h, to obtained catalyst rhodium iodide. The methyl acetate carbonylation process to synthesize acetic anhydride and acetic acid to demonstrate the high catalytic properties. The results showed that we synthesized high purity rhodium iodide and the catalytic performance is excellent, the dis- solvant can be recovered and the catalytic performance is same as the standard substance, the rhodium iodide produced this way have very good industrial application foreground.
