Description

Water diversion device for ethyl trifluorocrotonate production Technical Field The utility model relates to the technical field of ethyl trifluorocrotonate production, in particular to a water diversion device for ethyl trifluorocrotonate production. Background The synthetic route of ethyl trifluorocrotonate is to use ethyl trifluoroacetate as a starting material, the synthetic process is a one-pot method, the reaction process is divided into two steps, firstly, ethyl trifluoroacetate and ethyl acetate react (sodium ethoxide is used as a catalyst) to synthesize ethyl trifluoroacetoacetate, then ethyl trifluoroacetoacetate and ammonium acetate react to generate a target product, the ethyl trifluoroacetoacetate and ammonium acetate react to form a reversible reaction, water is generated in the reaction process, the generation of water can obstruct the reaction speed, the conversion rate is influenced, the raw materials can not react completely all the time, and a water separator is needed to continuously remove the generated water. Chinese published patent (publication number: CN 213132032U) discloses a water separator for organic chemistry experiments, which comprises a water retaining mechanism, the water retaining mechanism comprises a connecting block, a T-shaped slip ring, a swivel, a T-shaped annular groove, a rubber ring, a screw rod, a water blocking column, a water passing hole and a through hole, wherein the water passing hole is formed in one side of the connecting block, the through hole is formed in the water passing hole, the T-shaped slip ring is fixedly connected to the top of the connecting block, the T-shaped annular groove is formed in the bottom of the swivel, the T-shaped slip ring is slidably connected to the inside of the T-shaped annular groove, the screw rod is connected with the inner side wall of the swivel in a threaded manner, the bottom end of the screw rod extends to the inside of the water passing hole through the through hole, during experiments, the swivel is driven to rotate through the rotating rubber ring, the screw rod moves up and down due to the arrangement of external threads, so that the water blocking column blocks the water passing hole, and excessive water can not enter the flat-bottom beaker through the connecting pipe when an experiment is performed towards the inside of a water distribution pipe, and excessive water can be discharged through the water distribution funnel smoothly.
