| titleOfInvention | Biphenyl skeleton chiral aminophenoloxy dinuclear zinc, magnesium compound and its preparation method and application |
| abstract | The invention discloses a biphenyl-skeleton chiral aminophenoloxy dinuclear zinc and magnesium compound, a preparation method thereof and an application in catalyzing lactone ring-opening polymerization. The preparation method comprises the following steps: directly reacting the neutral ligand with the metal raw material compound in an organic medium, and then obtaining the target compound through the steps of filtering and drying. The biphenyl skeleton chiral aminophenoloxy dinuclear zinc and magnesium compound of the present invention is a high-efficiency lactone ring-opening polymerization catalyst, which can be used to catalyze the polymerization of lactones such as lactide; especially for racemic lactone Esters can get polylactic acid with higher isotacticity. The advantages of the biphenyl skeleton chiral aminophenoloxy binuclear zinc and magnesium compounds of the present invention are very obvious: the raw materials are easy to obtain, the synthetic route is simple, the product yield is high, and it has high catalytic activity and stereoselectivity, and can obtain high Regularity, high molecular weight polyester material to meet the needs of the industrial sector. Its structural formula is shown below. |
