Question

how to convert ethene to 1,2 dichloroethane?​

Answer 1

Answer:

H2C=CH2 + Cl2 → ClCH2−CH2Cl

1,2-dichloroethane is also generated by the copper(II) chloride-catalysed oxychlorination of ethylene:

2 H2C=CH2 + 4 HCl + O2 → 2 ClCH2−CH2Cl + 2 H2O

In principle, it can be prepared by the chlorination of ethane and, less directly, from ethanol.

Answer 2

Answer:

HELLO !!

Explanation:

A process for preparing 1,2-dichloroethane which comprises...

(A) feeding an ethane-containing feed gas stream into a dehydrogenation zone and dehydrogenating ethane to ethane to give a product gas stream comprising ethane, ethane and secondary constituents,

(B) feeding the ethan- and ethene-containing dehydrogenation product gas stream as a single stream or a plurality of substreams, optionally after having separated off secondary constituents, into one or more chlorination zones, chlorinating ethene to 1,2-dichloroethane to give one or more product gas streams comprising 1,2-dichloroethane, ethane and possibly further secondary constituents, isolating 1,2-dichloroethane and one or more ethane-containing circulating gas streams and recirculating the ethane-containing circulating gas stream or streams to the ethane dehydrogenation.
