Novel method for efficiently synthesizing phenylalkyl ether

The invention belongs to the technical field of organic synthesis, and particularly relates to a novel method for efficiently synthesizing phenylalkyl ether, which comprises the following steps: (1) adding phenol and alkyl carbonate into a reaction tank, and stirring to uniformly mix; and (2) conveying the mixed raw material liquid into a fixed bed reactor filled with a catalyst through a constant-flux pump for reaction, introducing nitrogen in the whole reaction process, and carrying out condensation and gas-liquid separation on the reaction product, and sampling for analysis. The continuous flow fixed bed reactor is adopted, on the basis of a certain amount of catalyst, complete conversion of phenol can be achieved, alkyl carbonate can be recycled, the production cost is greatly reduced, high-purity phenylalkyl ether can be obtained, and the synthesis method is efficient, low in energy consumption and wide in application prospect. 本申请属于有机合成技术领域，具体为一种高效合成苯烷基醚的新方法，制备步骤如下：(1)向反应罐中加入苯酚和碳酸烷基酯，搅拌使其混合均匀；(2)将混合原料液通
