摘要： By a process for the production of 1,2-dichloroethane (EDC) by reaction of ethylene with chlorine in the liquid phase (direct chlorination), the heavy ends being separated from the obtained 1,2-dichloroethane in a heavy-ends column and in a downstream vacuum column and, for the purpose of heat recovery and heating of the column bottoms, a 1,2-dichloroethane part-stream from the direct chlorination passing through a heat exchanger (one attributed to each column) for indirect heat exchange with the bottom product of each column, the aim of the invention is to provide a solution in which the reaction enthalpy of the direct chlorination can be used in a variable manner, thus precluding the above-described disadvantages. This is achieved by using at least one falling-film evaporator for heating the column bottoms, the bottom product of the respective column being routed to the distributor at the head of the column.

摘要： The invention relates to a method for the production of 1,2-dichloroethane by direct chlorination using chlorine and ethene in which, despite low reaction temperatures during direct chlorination, reaction heat produced is nevertheless used. According to the invention, vaporous 1,2-dichloroethane obtained in the direct chlorination reactor is compressed and the compressed 1,2-dichloroethane is transported to heat exchangers whereby heat is given off by the 1,2-dichloroethane. The invention also relates to a device including a turbocompressor arranged directly after the direct chlorination reactor.

摘要： The present invention relates to a process for preparing hexafluoropropylene(CF3CF═CF2, HFP) from the pyrolysis of trifluoromethane(CHF3, R23) and tetrafluoroethylene(C2F4, TFE) and more particularly, to the process for preparing hexafluoropropylene from the pyrolysis of an admixture of R23 and TFE mixed in an appropriate molar ratio at below 900 which is lower than the conventional reaction temperature and longer residence time, after investigating the pyrolysis reaction of R23 and TFE by the computer simulation. The process for preparing HFP is performed by carefully controlling reaction temperature with heat balance resulted from an endothermic pyrolysis of R23 and an exothermic dimerization of TFE to prevent from carbon formation, recycling unreacted R23 and TFE in the product separated and purified from distillation column, adding fresh R23 additionally to keep an appropriate molar ratio of R23 and TFE, to improve a total yield of HFP and to minimize heat supply from outside.
