摘要
以邻苯二酚和溴乙烷为原料,在碱性条件及单一溶剂中合成了邻乙氧基苯酚。对影响反应的各种因素进行了探讨,确定了适宜的合成条件为反应温度65℃,反应时间3.5h,反应终点的pH值控制为3。在此条件下,邻乙氧基苯酚收率为87.6%。
o-Ethoxyphenol is synthesized from o-dihydroxybenzene and bromoethane in single solvent with alkalescenee. The factors influencing on the reaction are discussed, the suitable conditions for synthesis are as follows： the reaction temperature is 65℃ ,reaction time is 3.5h, the value of pH at the end point of reaction is 3. Under the above-mentioned conditions, the yield of o-ethoxyphenol is 87. 6%.
