Abstract
Abstract ABSTRACT OF THE DISCLOSURE The disclosure relates to a catalyst mixture consisting of anhydrous iron(III)chloride and a further mixing component, for making 1,2-dichloroethane by subjecting ethylene to reac-tion with chlorine in a solvent at atomospheric or elevated pressure. The mixture is more particularly characterized in that the further mixing component is a nitrogen base or a salt thereof, which is used in a proportion approximately equivalent to the iron(III)chloride proportion.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
51 words
A process for making 1,2-dichloroethane by subjecting ethylene to reaction with chlorine in a solvent at atmospheric or elevated pressure in the presence of a catalyst mixture con-sisting of anhydrous iron(III)chloride and a nitrogen base or a salt thereof, which is used in a proportion approximately equi-valent to the iron(III)chloride proportion.
Claim 2
Dependent Claim
51 words
A process for making 1,2-dichloroethane by subjecting ethylene to reaction with chlorine in a solvent at atmospheric or elevated pressure in the presence of a catalyst mixture con-sisting of anhydrous iron(III)chloride and a nitrogen base or a salt thereof, which is used in a proportion approximately equi-valent to the iron(III)chloride proportion.
Claim 3
Dependent Claim
85 words
A process for making 1,2-dichloroethane by subjecting ethylene to reaction with chlorine in a solvent at atmospheric or elevated pressure in the presence of a catalyst mixture con-sisting of anhydrous iron(III)chloride in a concentration of 0.005 to about 0.5 weight %, based on the quantity of solvent and a nitrogen base or a salt thereof, which is used in a pro-portion approximately equivalent to the iron(III)chloride pro-portion, and, if desired, an agent inhibiting the formation of by-products at a temperature of about 20 to 200°C.
Claim 4
Dependent Claim
85 words
A process for making 1,2-dichloroethane by subjecting ethylene to reaction with chlorine in a solvent at atmospheric or elevated pressure in the presence of a catalyst mixture con-sisting of anhydrous iron(III)chloride in a concentration of 0.005 to about 0.5 weight %, based on the quantity of solvent and a nitrogen base or a salt thereof, which is used in a pro-portion approximately equivalent to the iron(III)chloride pro-portion, and, if desired, an agent inhibiting the formation of by-products at a temperature of about 20 to 200°C.
Claim 5
Dependent Claim
