摘要
Catalyst system for the preparation of 1,2-dichloroethane by reaction of ethylene with chlorine in a solvent, if desired in the presence of an inhibitor for reducing the formation of by-products, which comprises a phenolate chloro complex of the formula… Me+n[Z+mClm.L]n… in which … … n is an integer from 1 to 3, … m is an integer from 1 to 6, … Cl is a chloride anion, … Me+ is a proton and/or metal cation of elements from main group I and/or II or from the lanthanide group of the Periodic Table of the Elements, … Z+ is a metal cation of elements from main group III, IV, V or VI or from subgroup I, IV, VI or VIII of the Periodic Table of Elements, and … L is a phenolate anion which is unsubstituted or substituted by chlorine and/or a hydroxyl group and/or an alkyl or chloroalkyl radical and/or an alkoxy or chloroalkoxy radical. … …??The invention furthermore relates to a process for the chlorination of ethylene using this catalyst system.
