| titleOfInvention | Rare earth alkoxide solution for asymmetric synthesis catalyst raw material and method for producing the same. |
| abstract | An object of the present invention is to provide a rare earth alkoxide solution for an asymmetric synthesis catalyst raw material that stably exhibits high catalytic activity, and to provide a production method thereof. A crude rare earth alkoxide solution obtained by the reaction of a rare earth metal and an alcohol or a crude rare earth alkoxide solution obtained by the reaction of a rare earth chloride and an alkali metal alkoxide in a solvent containing alcohol is completely distilled off and dried. The rare earth alkoxide solution with high catalytic activity and high reproducibility is produced by exchanging with C 6 -C 10 aromatic hydrocarbon or C 5 -C 12 saturated hydrocarbon solvent and filtering and adjusting the concentration. To do. |
