ABSTRACT:
A new and improved polymerization inhibitor composition, its method of manufacture, and its use in stabilizing the distillation of acrylic acid is made possible by the pre-oxygen-activation of N-nitrosophenylhydroxylamine in combination with hydroquinone mono-methyl-ether (often referred to as p-methoxyphenol) whereupon a synergistic performance of these components is disclosed.
