The invention relates to an ethyl formate and ethyl acetate co-production method, and belongs to the technical field of chemical product synthesis. The method comprises the steps that (1) methanoic acid, ethyl alcohol and acetic acid are pumped into a reaction rectifying tower by a raw material pump for reaction; (2) azeotropes of water, ethyl formate and ethyl acetate generated through reaction are cooled by a tower top condenser and then enter a layering device for layering; (3) supernatant liquid in the layering device enters a product tower for rectification; after the rectification, the substances at the tower top are ethyl formate, and the substances at the tower bottom are ethyl acetate; (4) lower layer liquid of the layering device is transferred to a recovery tower to be recovered. The methanoic acid is a raw material and is also a catalyst of two reactions; the environment pollution caused by using a concentrated sulfuric acid catalyst is avoided. A reaction rectification mode is used, so that the single-pass conversion rate of products can be improved. The method provided by the invention has the advantages that the preparation method is simple; safety and economic performance are realized; the cost is low; the efficiency is high; no solid catalyst is added; the environment pollution is avoided; the ethyl formate and ethyl acetate co-production can be realized.
