| titleOfInvention | Method for producing diketonabanadium (III) complex |
| abstract | PROBLEM TO BE SOLVED: To provide, in high yield, a diketonabanadium (III) complex which is useful as a polymerization catalyst for highly functional polypropylene and ethylene-propylene copolymer, and as a curing accelerator. The production method that can be obtained is provided. SOLUTION: A diketonate alkali metal salt is reacted with a vanadium salt (a water-soluble trivalent salt such as VCl 3 ) to form a compound represented by the general formula: (Wherein R1, R2, and R3 represent a C1-8 alkyl group, an aryl group, or a hydrogen atom.) In the method for producing a diketonatovanadium (III) complex represented by the formula: Adjusted to have a pH of 2.0 to 5.0, with respect to the vanadium salt, a theoretical equivalent of 0.7 to 1.2 mol. One-fold diketonate alkali metal salt is reacted at 0 to 60 ° C. |
