Ethyl vinyl ether

Ethyl vinyl ether (ethoxyethene) is a clear, low-boiling flammable liquid used industrially as a cationic polymerization monomer and in the laboratory to protect alcohols as acetal groups.

Ethylamine

Ethylamine, also known as ethanamine or aminoethane, is a two-carbon primary aliphatic amine (CH3CH2NH2), a colorless gas or liquid boiling at 16.6 °C and miscible with water, used chiefly to make triazine herbicides.
