Continuous synthesis of anisole in microreactor system
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.
