METHOD OF DETERMINING EFFICIENCY OF DEACTIVATING INHIBITORS OF METALS Russian patent published in 2001 - IPC

Abstract RU 2168714 C2

FIELD: analytical methods. SUBSTANCE: sample to be analyzed is oxidized in cumene in presence of oxidation initiator, in particular azo-bis- isobutyronitrile, and oxidation catalyst, in particular cobalt naphtenate, after which efficiency of inhibitor is found from oxidation rate retardation. EFFECT: simplified analytical procedure and increased determination accuracy. 1 tbl, 3 ex
