Embodiment Construction
[0025] Such as Figure 1 to Figure 3 Shown, be the purification method of a kind of pentafluoroethane of the present invention, comprise the steps:
[0026] (a) Preliminary reaction device: first check the airtightness of rectification tower 1, distillation tower 2, reflux tank 3 and fixed bed reactor by conventional methods, install liquid distributor 4 in rectification tower 1, and evenly arrange rectification Packing in tower 1 and distillation tower 2, and then preheating rectification tower 1 and distillation tower 2 to avoid air leakage in the device during operation and affect the yield of the product. The effect, thereby improving the purity of the finished product, preheating the device in advance can effectively reduce the extraction time, speed up the separation efficiency, and reduce energy consumption. The rectification column 1 is provided with a support grid 5, which is located below the liquid distributor 4, and a stainless steel corrugated wire mesh structure...
