- Method and device for preparing 2,3,3,3-tetrafluoropropene
-
The invention provides a method and a device for preparing 2,3,3,3-tetrafluoropropene. The device for preparing 2,3,3,3-tetrafluoropropene comprises a circulation flow reactor, a first rectifying tower, a first cooling tower, a second rectifying tower and a second cooling tower. The method provided by the invention adopts a continuous loop reactor technology to realize the technology of separatinghydrogen chloride by-products in real time under the reaction conditions, so that the selectivity of the reaction is greatly improved; since the continuous circulation operation of the raw materialsis realized, the total conversion rate of the reaction is very high. 2,3,3,3-tetrafluoropropene obtained by the method is low in cost; the production technology has the advantages of being few in by-products and wastes and suitable for industrial large-scale production.
