| titleOfInvention | Process for chlorination,dehydrochlorination and purification of organic compounds |
| abstract | A process is provided for producing trichlorethylene, tetrachlorethylene or mixtures thereof including the steps of (1) reacting chlorine and ethylene in a liquid body containing predominantly chlorethanes, which chlorethanes have an average composition of at least 2.5 chlorine atoms per molecule; (2) maintaining the chlorethanes at a temperature in the range of 0* to 250* C.; (3) removing at least a portion of said chlorethanes and separating said removed material into a heavier product fraction containing a predominant amount of chlorethane having at least four chlorine atoms per molecule and a lighter fraction having an average chlorine content which is lower than that of said first fraction, the ratio of the number of mols of the heavier fraction to the number of mols of the lighter fraction being in the range of 1:0.1 to 1:30; (4) employing at least a portion of the said lighter fraction as liquid body in a subsequent chlorination reaction in accordance with steps (1), (2) and (3); and (5) dehydrochlorinating the heavier product fraction of step (3) by (6) maintaining the heavier product fraction at an elevated temperature in the liquid state while under positive pressure and in the presence of activated carbon. |
