Stabilizing water-aromatic solvent mixtures, e.g. quenching mixtures from acetylene production, by adding N-oxyl, aromatic or aliphatic amine or phenol as polymerization inhibitor

摘要

A method for stabilizing mixtures containing water and aromatic solvent(s) involves addition of polymerization inhibitor(s) (I) selected from N-oxyls, aromatic amines, aliphatic amines and/or phenols. Independent claims are included for: (1) mixtures containing water, aromatic solvent(s) and (I); and (2) the use of (I) for stabilizing mixtures containing water and aromatic solvent(s), specifically by reducing polymerization.
