Patent statistics and analysis of 2,3,3,3-tetrafluoropropene's preparation is made, also the method of the preparation of 2,3,3,3-tetrafluoropropene on Dupont and Honeywell is reviewed. Based on the statistics data, two important lines for making 2,3,3,3-tetrafluoropropene are proposed. The process involes reacting one starting material selected from the group consisting of halopropanes (such as 1,1,1,3-tetrachloropropane,HCC-250fb, that can be obtained by telomerization of tetrachloromethane and ethylene) with HF and C12. Another process involes the hydrofluorination of halopropenes (such as 1,1,2,3-tetrachloropropene, HCC-1230xa, that can be obtained by hydrochlorination of 1,2,3-trichloropropane) followed by dehvdrohalo~enation of the intermediate.
