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.
The methoxylation of α \|pinene catalyzed by macroporous sulfonic resin has been studied. The effects of reaction temperature and solvent on reaction activity were investigated. The results indicated that conversion of α \|pinene on macroporous sulfonic resin obeyed guasi\|first order reaction modle and activation energy of methoxylation of α \|pinene was 55.94 kJ/mol.
