Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing dodecacarbonyl triruthenium having the following Formula, the method comprising a process of carbonylating ruthenium chloride with carbon monoxide, wherein 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 2. The method for producing dodecacarbonyl triruthenium according to claim 1 , wherein an amine to be added is an amine having 3 to 36 carbon atoms. 3. The method for producing dodecacarbonyl triruthenium according to claim 1 , wherein a reaction time is 10 to 30 hours. 4. The method for producing dodecacarbonyl triruthenium according to claim 1 , wherein ruthenium chloride is a ruthenium chloride solution including ruthenium chloride and an organic solvent, and the organic solvent is methanol, ethanol, propanol and butanol. 5. The method for producing dodecacarbonyl triruthenium according to claim 4 , wherein the organic solvent is an organic solvent having a water content of 5% by mass or less. 6. The method for producing dodecacarbonyl triruthenium according to claim 2 , wherein a reaction time is 10 to 30 hours. 7. The method for producing dodecacarbonyl triruthenium according to claim 2 , wherein ruthenium chloride is a ruthenium chloride solution including ruthenium chloride and an organic solvent, and the organic solvent is methanol, ethanol, propanol and butanol. 8. The method for producing dodecacarbonyl triruthenium according to claim 3 , wherein ruthenium chloride is a ruthenium chloride solution including ruthenium chloride and an organic solvent, and the organic solvent is methanol, ethanol, propanol and butanol.
