Sour sulfhydryl group containing oils are treated with an effective amount of a sweetening, hydrogen sulfide vapor reducing quaternary ammonium compound of the formula ##STR1## (a) wherein (i) R.sup.1, R.sup.2 and R.sup.3 are hydrocarbon groups including alkyl, aryl, alkaryl or arylalkyl groups, of up to 24 carbon atoms, and if an alkyl group, may include a cycloalkyl; with the proviso that two of R.sup.1, R.sup.2 and R.sup.3 may be in saturated heterocyclic ring which includes said nitrogen atom and may also include an oxygen atom; and (ii) at least one of R.sup.1, R.sup.2 and R.sup.3 has two or more carbon atoms; and (b) wherein R.sup.4, R.sup.5, R.sup.6 and R.sup.7 independently are hydrogen or a hydrocarbon group of up to six carbon atoms, with the proviso that two of R.sup.4, R.sup.5, R.sup.6 and R.sup.7 may be in a cycloalkane ring. The compounds used in this treatment are especially suitable for high boiling, heavy residual fuels under low mix conditions.
A method of sweetening sour oils, which comprises reacting hydrogen sulfide contained in said oils with an effective sweetening amount of a dipolar compound to produce organosulfur compounds, said dipolar compound comprising a quaternary ammonium ion of the formula ##STR7## (a) wherein (i) R.sup.1, R.sup.2 and R.sup.3 are hydrocarbon groups including alkyl, aryl, alkaryl or arylalkyl groups, of up to 24 carbon atoms, and if an alkyl group, may include a cycloalkyl;
A method of reducing hydrogen sulfide vapor in a vapor space above confined oil, which comprises reacting hydrogen sulfide contained in said oil and said vapor with an effective hydrogen sulfide reducing amount of a dipolar compound to produce organosulfur compounds, said dipolar compound comprising a quaternary ammonium ion of the formula ##STR8## (a) wherein (i) R.sup.1, R.sup.2 and R.sup.3 are hydrocarbon groups including alkyl, aryl, alkaryl or arylalkyl groups, of up to 24 carbon atoms, and if an alkyl group, may include a cycloalkyl;
A method of reducing noxious odors of hydrogen sulfide, mercaptans and other sulfhydryl compounds in the atmosphere from oil which comprises reacting hydrogen sulfide contained in said atmosphere and said oil with an effective odor reducing amount of a dipolar compound to produce organosulfur compounds, said dipolar compound comprising a quaternary ammonium ion of the formula ##STR9## (a) wherein (i) R.sup.1, R.sup.2 and R.sup.3 are hydrocarbon groups including alkyl, aryl, alkaryl or arylalkyl groups, of up to 24 carbon atoms, and if an alkyl group, may include a cycloalkyl;
