摘要

苯甲醚是一种重要的溶剂和有机合成中间体，以往通过间歇反应合成，存在生产效率低下、操作周期长等问题，亟需开发连续化的生产装置和技术。提出以苯酚钠水溶液和硫酸二甲酯为原料通过连续微反应器合成苯甲醚的方法。该方法利用微混合器和局部收缩的反应管道强化反应物的混合，在近似绝热的反应条件下快速完成反应过程。报道了苯酚钠浓度、反应物流量和反应物摩尔比对于微反应器内苯酚钠转化率和硫酸二甲酯利用率的影响规律。与文献报道的间歇反应进行了对比，揭示了微反应技术的优势。

Abstract

Anisole is an important solvent and organic synthesis intermediate. In the past

it was synthesized by batch reaction

which has problems such as low production efficiency and long operation cycle. A continuous synthesis device and technology for anisole is highly required. A continuous-flow microreaction method using sodium phenolate solution and dimethyl sulfate as reactants was proposed. The microreactor employs micromixer and locally constructive reaction tube to enhance reactant mixing and the reaction was carried out at approximately adiabatic condition. The influences of sodiumphenolate concentration

reactant flow rate and molar ratio of phenolatetodimethyl sulfate on the sodium phenolate conversion and dimethyl sulfate utility were reported. A comparison with the batch reaction in the literatures was provided to show the advantage of microreaction technology.
