| titleOfInvention | A kind of preparation method of the aluminium methyl coordination compound of four tooth nitrogen oxygen parts |
| abstract | The preparation method that the invention discloses the aluminium methyl coordination compound of a kind of four tooth nitrogen oxygen parts, step is: by N, N '-dimethyl-? N, N '-diphenyl ethylene diamine reacts with the benzaldehyde of benzaldehyde or replacement under n-BuLi exists, and obtains four tooth nitrogen oxygen parts; Part is added at-20��0 DEG C the trimethyl aluminium of equimolar amounts, after adding, rises to room temperature, then heat to 80 DEG C of reaction 12h, carry out after having reacted processing to obtain aluminum complex; Shown in the described following formula I of complex structure formula. Preparation method of the present invention is simple, gained part performance is good, generation aluminum complex can be reacted with alkyl aluminum, the ring-opening polymerization of the efficient catalysis lactide of described aluminium methyl coordination compound energy, catalyst activity is high, stereochemical structure and the molecular weight of polymer can be regulated and controled, meet different demands, have good market prospect. |
