METHOD OF CLEANING PROCESS EQUIPMENT TO REMOVE POLYMER AND RESIN DEPOSITS Russian patent published in 2005 - IPC

Abstract RU 2243830 C1

FIELD: cleaning processes.

SUBSTANCE: cleaning is accomplished by way of destruction, in particular in monomer and polymer production processes. Method comprises treating equipment with a destroying system, particularly with 0.0001 to 40% solution of 2,2',6,6'-tetramethyl-4-oxopiperidine-1-oxyl or a mixture thereof with 2,2',6,6'-tetramethyl-4-oxopiperidine-4-fulvene in organic solvent.

EFFECT: prolonged operational cycle due to enabled on-line cleaning procedure and reduced loss of desired products.
