Description

technical field [0001] The invention relates to the technical field of synthesis of foaming agents and intermediates of refrigerants, in particular to a synthesis device and method for 2-chloro-3,3,3-trifluoropropene. Background technique [0002] As we all know, fluorocarbons have been widely used in industries, including refrigerants, aerosol propellants, blowing agents, heat transfer media, and gaseous dielectrics. Due to the recent discovery of the possible environmental problems of perhalogenated fluorocarbons, namely their relatively high global warming potential, researchers in the above-mentioned industrial fields have endeavored to find a compound that has zero ozone depletion potential The fluid with the lowest possible greenhouse warming potential, from which 2,3,3,3-tetrafluoropropene (HFO-1234yf) is known to have zero ozone depletion and a low global warming potential (GWP=4) , so it is identified to meet the environmental requirements, it has the advantages of...
