Efficient mixing equipment for preparing hexafluoropropane and preparation method

The invention discloses efficient mixing equipment for hexafluoropropane preparation and a preparation method, and relates to the technical field of organic synthesis.The efficient mixing equipment comprises a rack, a top plate, a mixing reaction tank and a stirring assembly. Gaseous raw materials discharged by the high-pressure nozzle and liquid raw materials discharged by the liquid raw material tank can be mixed at the initial stage of entering the mixing reaction tank, so that raw material premixing is realized, the material mixing speed is higher, the mixing is more uniform, and the reaction is more thorough; a spiral stirring shaft in the stirring assembly can convey reaction raw materials in the middle area in the mixing reaction tank upwards in a spiral mode, up-down rolling of the raw materials is achieved, horizontal stirring of a stirring rod is matched, liquid raw materials and gaseous raw materials are made to make full contact, full reaction is achieved, and the reaction is more thorough; and th
