摘要
以二异丙醇胺(DIPA)和丙烯酸甲酯(MA)为原料通过Michael加成反应制得一种AB2型单体(N,N-二异羟丙基-3-胺基丙酸甲酯)。通过单因素实验分析方法分别考察了相关因素对该反应的影响,得出了最优的反应条件:采用MA滴入DIPA的加料方式;以甲醇作溶剂;n(DIPA):n(MA)=1∶1.5;反应温度为40℃,反应时间为4h。并利用FT-IR、1H-NMR等方法对单体的分子结构进行了表征。
N, N- dihydroxypropyl -3 -amine -methylpropionate was synthesized via Michael addition action of methyl acrylate and diisopropanolamine. By the method of single - factor experimental design, some correlative factors how to influence the action were investigated, the appropriate action conditions were optimized： dripping MA to DIPA, methyl alcohol was as solvent, the mol ratio of DEA and MA was 1： 1.5, reaction time was 4h and temperature was 40~C, the monomer was characterized by FT - IR and ^1H - NMR meanwhile.
