ABSTRACT:
Certain Mannich reaction products formed from the reaction of an alkyl substituted catechol, a polyamine, and an aldehyde are used to deactivate copper metal species contained in hydrocarbon fluids. Left untreated, such copper species lead to decomposition resulting in the formation of gummy, polymer masses in the hydrocarbon liquid.
