Abstract:
A method for scavenging sulfhydryl compounds from a substantially water free hydrocarbon substrate comprising a sulfhydryl content, said method comprising:reacting an alkanolamine with a paraformaldehyde to form a condensation product comprising a water content and a sulfhydryl scavenging compound having the following general structure: ##STR2## wherein n is from about 1 to about 2,R.sup.1 and R.sup.2 independently are selected from the group consisting of hydrogen, phenyl groups, and linear, branched, or cyclic alkyl, alkenyl, and alkynyl groups having from about 1 to about 6 carbon atoms, treating said condensation product to reduce said water content, producing sulfhydryl scavenging agent comprising about 5% water or less; andmixing said substrate with an amount of said sulfhydryl scavenging agent effective to reduce said sulfhydryl content of said substrate.
