摘要
Synthesis of diallylmethylamine from lower concentration methylamine water solution and allylchloride has been performed using polyglycol-400(PEG-400) as phase transfer catalyst. The results show that the reaction time can be efficiently shortened and product yield can be significantly increased. The orthogonal experimental method has been used to optimize the experiment conditions. The optimal condition are as follows:PEG-400 phase transfer catalyst, mole ratios of allylchloride∶methylamine=2.2∶1, the two periods of reaction temperature and time 20 ℃(1 h) and 60 ℃(6 h), diallylmethylamine is obtained in 75.6% yield. The product is characterized by IR, GC-MS and 1H NMR.
