Abstract: PURPOSE: A continuous polytetrafluoroethylene(PTFE) pyrolysis apparatus and a method for preparing PTFE using the apparatus are provided, to obtain tetrafluoroethylene of high purity massively with low cost. CONSTITUTION: The apparatus comprises at least two PTFE main tanks(10) which stores PTFE powder or particle and can be operated alternatively; a PTFE auxiliary tank(11) which is connected with the main PTFE main tanks(10) through a ball valve(24) and a transparent hose(12) for vacuum and stores PTFE supplied from the main tanks(10) temporarily before PTFE is applied to the process; a vertical-type screw feeder(13) which is operated by a motor and a magnetic driver, whose rotation number can be controlled, and which injects the PTFE supplied from the auxiliary tank(11) into a pyrolysis reactor through a cooler(15); and a vertical-type pyrolysis reactor(14) which pyrolyzes the PTFE supplied from the screw feeder(13) to generate tetrafluoroethylene gas and delivers the generated tetrafluoroethylene gas to a tetrafluoroethylene condensation tank.

Abstract: PURPOSE: A continuous preparation of perfluoroethyliodide denoted by C2F5I is accomplished under activate liquid catalyst. The compound is used in a variety of water/oil repellent process or contaminant-resistant agents and high performance surfactant. CONSTITUTION: A continuous preparation of perfluoroethyliodide is performed by using iodide, pentafluoroiodide, tetrafluoroethylene(TFE) and reaction catalyst. The preparation comprises further continuously introducing TFE under room pressure and in the presence of antimony pentafluoride (SbF5) reaction catalyst in liquid state to produce perfluoroethyliodide product. The iodide and iodide pentafluoride is admixed together in a reaction molar ratio (I2/IF5) of 0.02-5 and the reaction catalyst SbF5 is dissolved under stirring at room temperature to 50 deg.C.
