摘　　要：三氯化铑与氢碘酸直接合成碘化铑,在最佳反应条件下,合成的收率达到98.5%,产品晶形均一,氯离子含量小于50 mg/kg。A new method has been introduced to synthesize rhodium iodide, an important homogenous catalyst for earbonylation of methanol, to overcome shortcomings of the present methods. These shortcomings include low yield, poor quality and unacceptability with respect to industrial manufacturing. The new method involves the direct reaction of RhC13 with HI. The yield is up to 98.5% and Cl-ean be minimized to 50 ppm by optimizing synthetic operations, superior to the reported data.
