摘要： 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.

摘要： The present invention is directed to the use of hydroxylamine, its acid salts or mixtures thereof to prevent fouling during the basic washing of hydrocarbons containing oxygenated compounds. More specifically, oxygenated compounds such as carbonyl containing organics have a tendency to polymerize, producing fouling elements when such are contained in hydrocarbons being washed with basic materials. The hydroxylamine and its salts are quite effective in reducing the fouling tendencies due to these specific mechanisms.
