摘要： Hydrogen sulfide (H
2 S) and/or mercaptan scavengers are chemicals that remove H
2 S and/or mercaptans from gas, oil and water. Water-based formulations may be made and used employing scavenging compounds having the formulae:(A) (B) wherein each R
1 , R
2 , R
3 , and R
4 are the same or different and are selected from the group consisting of hydrogen, an alkyl, an alkenyl, an aryl, an acyl, a halogen, a hydroxyl, a nitro, an alkyl ester, an aryl ester, an alkyl ether, an aryl ether, a hydroxymethyl, an anhydride group, an amino, and a sulfide. In one non-limiting embodiment the compounds (A) and (B) do not contain nitrogen atoms. Water-based formulations, such as those using a protic solvent with the above compounds, work well as H
2 S scavengers.

摘要： Maleated fatty acids that are functionalized with materials such as polyols, alkanolamines and/or alkylene oxides have been discovered to improve the properties of various fluids. In a non-limiting example, functionalized maleated fatty acids having acid numbers less than 10 may improve the lubricity of fuels and lubricants, such as hydrocarbon fuels and lubricants, when added thereto.

摘要： Mercaptans and/or hydrogen sulfide (H
2 S) in hydrocarbons, naphthas, gasolines, and the like may be scavenged therefrom by being brought into intimate contact with a mercaptan scavenger formulation containing at least one disubstituted azodicarboxylate of the formula R
1 OOCN=NCOOR
2 , where R
1 and R
2 are independently alky! groups, alkenyl groups and aromatic groups having from 1 to 18 carbon atoms. These scavengers remove mercaptans and/or H
2 S from hydrocarbons faster than many conventional mercaptan scavengers. An effective scavenging amount of disubstituted azodicarboxylate in the hydrocarbon fluid ranges from about 5 to about 20 parts by weight based on 1 part as sulfur of mercaptan and/or H
2 S.
