Abstract
The present invention provides a number of agents that are useful to inhibit aldol condensation in caustic scrubbers. Preferred agents include, but are not necessarily limited to benzoic hydrazide, hydroperoxides, hydrogen peroxide, salts of hypochlorous acid, nitroalkanes, monoethanolamine, peroxyesters, and N,N-dialkylhydroxylamines.
Claims21
A method for inhibiting aldol condensation in caustic scrubbers comprising the step of treating a caustic scrubbing solution comprising hydrocarbons with an inhibiting agent in an amount sufficient to inhibit said aldol condensation, wherein said inhibiting agent is selected from the group consisting of benzoic hydrazide, hydroperoxides, hydrogen peroxide, salts of hypochlorous acid, nitroalkanes, monoethanolamine, peroxyesters, and N,N-dialkylhydroxylamines.
A method for inhibiting aldol condensation in caustic scrubbers comprising the step of treating a caustic scrubbing solution comprising hydrocarbons with an inhibiting agent in an amount sufficient to inhibit said aldol condensation, said inhibiting agent being selected from the group consisting of benzoic hydrazide, tertiary-butyl hydroperoxide, hydrogen peroxide, NaOCl, Ca(OCl).sub.2, nitromethane, monoethanolamine, tertiary-butyl perbenzoate, and N,N-diethylhydroxylamine.
A caustic scrubbing solution comprising hydrocarbons and an inhibiting agent in an amount sufficient to inhibit aldol condensation, wherein said inhibiting agent is selected from the group consisting of benzoic hydrazide, hydroperoxides, hydrogen peroxide, salts of hypochlorous acid, nitroalkanes, monoethanolamine, peroxyesters, and N,N-dialkylhydroxylamines.
