    摘要: 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.

    摘要: This invention relates to processes and compositions for color stabilized distillate fuel oils which comprises an effective color stabilizing amount of (a) a tertiary amine having the formula ##STR1## wherein R and R' are the same or different alkyl groups having one to about six carbon atoms, and (b) a hydroxylamine having the formula ##STR2## wherein R and R' are the same or different and are hydrogen, alkyl, alkaryl or aralkyl groups, wherein the weight ratio of (a):(b) is from about 1:1 to about 99.7:0.3. Preferably, the alkyl, alkaryl and aralkyl groups of the hydroxylamine have from one to about twenty carbon atoms. It is further preferred that (a) is N,N-dimethylcyclohexylamine and (b) is N,N-diethylhydroxylamine.
