PROCESS FOR PRODUCING ETHYLENE-DICHLORID BY OXYCHLORINATING ETHYLENE |
摘要 |
Ethylene is selectively oxychlorinated to ethylene dichloride by the process of contacting ethylene, hydrogen chloride and molecular oxygen in the vapor phase at a temperature of from about 450 DEG F to about 670 DEG F in the presence of a fixed-bed, supported cupric chloride catalyst. Ethylene is introduced into the inlet portion of the reaction zone in a sufficient stoichiometric excess and hydrogen chloride and molecular oxygen are added to the reaction zone in a sufficient plurality of points throughout the reaction zone to maintain the hydrogen chloride: ethylene molar ratio below about 0.7 and the oxygen: ethylene molar ratio below about 0.12 in the reaction mass during passage through the reaction zone. |
