摘要
以硫酸二甲酯和邻苯二酚为原料，在碱性条件及相转移催化剂的作用下合成了愈创木酚。并且对影响反应的各种因素进行了研究，确定最佳的工艺条件为邻苯二酚与硫酸二甲酯的投料比为１∶１２，邻苯二酚与氢氧化钠用量比为１∶１１９，相转移催化剂聚乙二醇８００的用量为８％，反应温度６０℃，反应时间３小时。得到的产品中单醚含量为８５％，单醚收率为８０８％。
Abstract In this paper,guaiacol was synthesized from catechol and dimethyl sulfate in the presence of phase transfer catalyst.Various factors which influence the monoalkylation reaction were investigated and optimum reaction conditions were determined .
