CN201010153085.9 discloses a method for preparing a carbonylated rhodium iodide solution. A method for preparing a carbonylated rhodium iodide solution is carried out according to the following steps: (1) dehydration and carbonylation: solid rhodium triiodide and anhydrous acetic acid are put into an autoclave, and after carbon monoxide is passed in, stirring is started, and the temperature is raised to 80-140C, and the pressure of the autoclave is adjusted to be 0.5-1.0 MPa, and the stirring is continued for 0-4h under these conditions; (2) dissolution: water is pumped into the reactor by a pump, and stirring continues for After 20-60min, a rhodium carbonyl iodide solution with rhodium concentration higher than 2000ppm is obtained. The rhodium carbonyl iodide solution with rhodium concentration of 2000-5000 ppm can be obtained in a short time according to the method of the present invention.
