Dutch Liquid, ethylene chloride (C2H4Cl2), is an oily liquid formed by the action of chlorine upon ethylene (C2H4). Owing to the formation of this liquid, the latter compound is also known as olefiant gas. It boils at 85°, and has a chloroform-like smell. It acts as an anaesthetic, but is not much used for this purpose.
