METHOD FOR PREPARING 1,2-DICHLOROETHANE WITH COMBINED ELIMINATION OF HEAT |
摘要 |
FIELD: chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of 1,2-dichloroethane by method of liquid-phase chlorination of ethylene. Method involves maintaining the optimal ratio of heat eliminated based on evaporation and heat eliminated based on cooling a liquid medium in a heat exchanger in the process. One-sixth part of heat formed in reactor is eliminated based on evaporation of synthesized compound in boiling and 5/6 part of formed heat is eliminated based on circulation of liquid working medium in external heat exchanger. The temperature gradient in the reaction zone is maintained equal 52°C. Invention provides enhancing selectivity of process and reducing amount of by-side products of reaction (higher chlorine-derivate of ethane). ^ EFFECT: improved method of synthesis. ^ 3 dwg, 1 ex |
