Compounds having the formulae and general formulae: wherein each R1, R2, R3 and R4 are the same or different and may be hydrogen, an alkyl group, an aryl group, a halogen, a nitro group, an alkyl or aryl ester, and an alkyl or aryl ether; compounds having the general formula: wherein R is an alk
Compounds having the formulae and general formulae: wherein each R1, R2, R3 and R4 are the same or different and may be hydrogen, an alkyl group, an aryl group, a halogen, a nitro group, an alkyl or aryl ester, and an alkyl or aryl ether; compounds having the general formula: wherein R is an alkyl, aryl or electron withdrawing group; mixtures thereof; can be used as additives for crude oil and hydrocarbons. These compounds may be used to scavenge mercaptans, sulfides, cyanides, and primary or secondary amines; either alone or in combination.

1. A method for treating a crude oil or a hydrocarbon comprising admixing crude oil or a hydrocarbon with an additive comprising at least one compound selected from the group consisting of: compounds having the general formula: wherein each R1, R2, R3 and R4 are the same or different and selected from the group consisting of hydrogen, an alkyl group, an aryl group, a halogen, a nitro group, an alkyl ester, an aryl ester, an alkyl ether, and an aryl ether;compounds having the general formula: wherein R is an alkyl or aryl group; and mixtures thereof;wherein the additive functions to scavenge mercaptans, sulfide, cyanides, primary amines and secondary amines; and the method is practiced in the absence of a strong base. 2. The method of claim 1 wherein the additive has the general formula: and R1, R2, R3 and R4 are each hydrogen. 3. The method of claim 1 wherein the additive has the general formula: and R is an alkyl, aryl, or electron withdrawing group. 4. The method of claim 3 wherein R is selected from the group consisting of hydrogen, butyl, octyl, and nonyl groups. 5. The method of claim 1 wherein the method is practiced in the presence of water. 6. The method of claim 1 wherein the water is present at a total concentration for from about 1 to about 15 percent by weight. 7. The method of claim 1 wherein the hydrocarbon is a fuel oil. 8. The method of claim 1 wherein the hydrocarbon is an organic chemical. 9. The method of claim 1 wherein the additive functions to scavenge mercaptans.
