摘 要:本论文以取代苯酚为原料,采用碳酸二甲酯为甲基化试剂,在相转移催化体系中引入醋酸镁,提高了碳酸二甲酯的反应活性,有效降低了反应的温度,缩短了反应时间,并以优良的收率(97~98%)制备得到一系列苯甲醚类化合物。与文献中的合成方法相比,本论文所用的合成方法具有反应温度较低(90~100℃),时间短(5 h),以及催化剂可回收利用等优点。Substituted phenol was used as raw material,dimethyl carbonate was used as methylation reagent,and magnesium acetate was introduced into the phase transfer catalytic system,which improved the reaction activity of dimethyl carbonate,effectively reduced the reaction temperature and shortened the reaction time,and a series of anisole compounds were prepared with excellent yields(97~98%).Compared with the synthesis methods in the literature,the synthesis method used in this paper has the advantages of lower reaction temperature(90~100℃),shorter reaction time(5 hours)and recyclable catalyst.
