Abstract

The production of 1,2-dichloroethane from ethylene, hydrogenchloride and oxygen or an oxygen-containing gas (oxi-chlorination)is done advantageously in a reactor with a lower boundary for acatalyst-fluidised bed, a first gas inlet duct (distributor pipes)(4) being provided above the boundary within the catalyst-fluidbed. The first gas inlet duct is provided with nozzles (5)distributed over the entire cross-section of the reactor, thesenozzles open out into pipes (6) which conduct the emerging gasstream in a direction essentially opposed to that of the gasstream which Fluidises the catalyst after entering via a secondgas inlet duct (7) below the boundary.8 claims, 1 figures
