| titleOfInvention | Beta-ketimine ligand aluminum compound, and preparation method and application thereof |
| abstract | The invention discloses a beta-ketimine ligand aluminum compound, and a preparation method and application thereof in catalyzing lactone ring opening polymerization. The preparation method comprises the following steps of: enabling beta-ketimine ligands to directly react with aluminum raw material compounds in methylbenzene, and then conducting filtration, concentration and recrystallization to obtain target compounds from reaction products. The beta-ketimine ligand aluminum compound provided by the invention is a high-efficiency catalyst for lactone ring opening polymerization and can be used for polymerization and copolymerization of lactide, epsilon-caprolactone and the like. The beta-ketimine ligand aluminum compound provided by the invention has very remarkable advantages that the raw materials are easy to obtain, the synthesis line is simple, the product yield is high, the property is comparatively stable, the catalytic activity is higher, high-molecular-weight polylactide, polycaprolactone and copolymers thereof can be obtained, and the needs of industrial departments can be met. The structural formula of the beta-ketimine ligand aluminum compounds is shown in the description. |
