摘要: 以甲基丙烯酸二甲胺基乙酯和氯化苄为原料合成了甲基丙烯酰氧乙基二甲基苄基氯化铵,分析了温度、原料配比、反应时间、溶剂量等因素对产品产率以及洗涤次数对产品纯度的影响。结果表明:在试验条件下,提高反应温度和延长反应时间有利于产品产率的提高;产品产率随二氯甲烷用量的增加先增加后下降,而随反应体系中氯化苄摩尔量的增加而先增大后趋于平稳。采用傅里叶变换红外光谱(FT-IR)对产物进行了表征;通过正交实验确定了最佳反应条件。
Abstract: The synthesis of Methacryloyl Oxyethyl Dimethylbenzyl Ammonium Chloride (DMBC) was carried out with dimethylaminoethyl methacrylate and benzyl chloride as raw materials and the effects of reaction temperatures, ratio of raw materials, reaction time and solvent amounts on yields of DMBC as well as the relation of washing times to the purity of the product were studied. The result showed that the increase of reaction temperature and prolonging the reaction time are conducive to the improvement of product yields. The product yield increases and then decreases with the quantity increase of the solvent dichloromethane, but increases and then levels off with the amounts of benzyl chloride. The molecular structure of the product was determined by means of Fourier transform infrared spectroscopy (FT-IR) and the optimum reaction conditions were obtained by orthogonal experiments.
