Abstract

The invention discloses equipment for producing ethyl acetate by using the ionic liquid dehydration technology. A reactive distillation module is connected with an acetic acid recovery module, the acetic acid recovery module is connected with a catalyst module, the catalyst module is connected with the reactive distillation module, and the reactive distillation module comprises a reactive distillation tower; the reactive distillation column is respectively connected with an acetic acid storage tank, an ethanol storage tank and an ionic solution tank; a first condenser is arranged at the top end of the reactive distillation tower; a first reboiler is arranged at the bottom end of the reactive distillation tower; according to the process disclosed by the invention, the ethyl acetate can reach high purity only through simple subsequent re-separation and even without subsequent separation, and the formula ionic liquid catalyst can be recycled only through simple water removal, so that the separation process is greatly simplified, and the investment of the separation procedure is saved.

Description

technical field [0001] The present invention relates to technical field of ethyl acetate production, be specifically related to a kind of equipment and the method that utilize ionic liquid dehydration technology to produce ethyl acetate. Background technique [0002] The ethyl acetate production process is mainly synthesized by acetic acid and ethanol under the action of a catalyst; the domestic production device uses concentrated sulfuric acid as a catalyst. The method is mature and the reaction conditions are mild, but the process has many steps and consumes a lot of energy. low efficiency. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the invention provides a kind of equipment and method utilizing ionic liquid dehydration technology to produce ethyl acetate, which solves the low problem of reaction efficiency. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005...
