Abstract: The present disclosure generally relates to methods of electrochemical coupling of thiols to form disulfide compounds. A method of synthesizing a disulfide compound is provided. The method may include providing an electrochemical cell that has a compartment, an anode, and a cathode. The compartment may contain a solution of one or more thiol compounds, a catalyst, and a solvent. The method may also include providing an electrical current to the electrochemical cell and converting the one or more thiol compounds into the disulfide compound.

Abstract: The disclosure provides compositions and methods that are useful in removing, lowering, or otherwise controlling hydrogen sulfide and mercaptans. The compositions and methods can be used in any industry where hydrogen sulfide poses problems, such as when dealing with crude oil based, natural gas based, and/or coal based products. In some embodiments, the compositions include one or more alkoxylated amino formaldehyde adducts.
