8-N-arylamine-hydrogenation quinoline complexation aluminum alkyl compound and preparation method and application thereof

Abstract

The invention discloses an 8-N-arylamine-hydrogenation quinoline complexation aluminum alkyl compound and a preparation method and application thereof. The preparation method of the 8-N-arylamine-hydrogenation quinoline complexation aluminum alkyl compound comprises the following steps that 8-N-arylamine-hydrogenation quinoline ligand is dissolved in an anhydrous solvent, aluminum alkyl is added, stirring is carried out under protection of nitrogen at the room temperature, the solvent is removed through decompression, a poor solvent is used for carrying out washing for three times, and the target aluminum alkyl compound is obtained. The 8-N-arylamine-hydrogenation quinoline complexation aluminum alkyl compound is an efficient lactone and lactide ring-opening polymerization catalyst and can be used for lactone and lactide ring-opening polymerization reaction. According to the 8-N-arylamine-hydrogenation quinoline complexation aluminum alkyl compound, the raw materials are low in price and easy to get, the synthetic route is simple, the product yield of high, characters are stable, the prepared product is abundant and changeable in structure, the catalytic performance is easy to regulate, the requirements of different kinds of lactone and lactide ring-opening polymerization can be met, prepared aliphatic polyester high polymer material is controllable in structure and performance, and requirements of industrial departments can be met.

Description

technical field

[0001] The invention relates to a preparation method and application of a class of organoaluminum compounds, in particular to an 8-N-arylamine-hydroquinoline complexed alkylaluminum compound, a preparation method and its application in ring-opening polymerization of lactones and lactides. Background technique

[0002] In the transition from an exhausted resource economy to a renewable resource economy, countries all over the world attach great importance to the development and application of degradable polymer materials. It is a new generation of promising materials and meets the requirements of ecological and sustainable development. Among them, aliphatic polyester is a very important class of degradable polymer materials, which has developed rapidly in recent years.

[0003] Aliphatic polyester can be completely biodegraded under natural environmental conditions without any pollution to the environment. Its excellent biocompatibility, permeability and low t...
