METHOD FOR INHIBITION OF POLYMERIZATION PROCESS OF VINYLAROMATIC HYDROCARBONS Russian patent published in 2004 - IPC

Abstract RU 2243201 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention describes a method for inhibition of the polymerization process of vinylaromatic hydrocarbons by addition of inhibitor based on 2,2',6,6'-tetramethyl-4-oxopiperidine-1-oxyl in organic solvent. Before addition inhibitor is activated by its treatment with nitrogen. Invention provides enhancing effectiveness of inhibition of the premature polymerization of vinylaromatic hydrocarbon and reducing consumption of inhibitor.

EFFECT: improved inhibition method.
