ABSTRACT:
Certain Mannich reaction products (i.e., alkylated phenol, polyamine, and an aldehyde) are used to deactivate first row transition metal species contained in hydrocarbon fluids. Left untreated, such metals lead to decomposition resulting in the formation of gummy, polymer masses in the hydrocarbon liquid.
