摘要:
Processes are described comprising: (i) providing a reactant comprising 1,2-dichloroethane; and (ii) reacting the reactant with ammonia to form a reaction product comprising one or more ethylene amines and hydrogen chloride, wherein the reaction is carried out in the presence of an organic, nitrogen- or phosphorus-containing compound which reacts with the hydrogen chloride to form an ionic liquid.
