摘要
针对席夫碱类催化剂在催化性能上的优势,以PMBP、2-氨基密啶等作为原材料,制备合成一种席夫碱铜类配体催化剂。通过红外光谱仪,分析了配体和催化剂的光谱图,并以甲基丙烯酸甲酯为例,对催化剂的催化性能进行了验证。结果表明,在温度80℃,反应时间24 h,摩尔比为1 000:1的情况下,得到的聚甲基丙烯酸甲酯的分子量最大。
In view of the advantages of the Sc,hiff base catalysts in catalytic performance,Schiff-base copper ligand catalyst was prepared by using PMBP and 2-aminopyrimidine as raw materials,and the spectra of the ligand and catalyst were analyzed by the infrared spectrometer.Taking methyl acrylate as an example,the catalytic performance of the catalyst was verified.The results showed that the molecular weight of prepared polymethyl methacrylate was the largest under the reaction conditions of the temperature of 80℃,the reaction time 24h,and the molar ratio of 1000:1.
