| 发明名称 | Production method for dodecacarbonyl triruthenium | ||
| 摘要 | The present invention is a method for producing dodecacarbonyl triruthenium (DCR) including a process of carbonylating ruthenium chloride with carbon monoxide, in which an amine is added to a reaction system at 0.8 molar equivalent or more with respect to chlorine of the ruthenium chloride and the carbonylation is conducted at a reaction temperature of 50 to 100° C. and a reaction pressure of 0.2 to 0.9 MPa. According to the present invention, it is possible to produce dodecacarbonyl triruthenium having less residual impurity metals without applying a reaction condition of a high pressure. | ||
