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.

Preparation of disulfide corrosion inhibitors by electrochemical methods

Disclosed herein are scavenging compounds and compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed herein are methods of using the compounds and compositions as scavengers, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.

Hydrogen sulfide scavengers

The present invention generally relates to compositions and methods for inhibiting corrosion at a surface in the production, transportation, storage, and separation of crude oil and natural gas.

Thiol-formyl hemiacetal corrosion inhibitors

Compounds, compositions and methods are provided for inhibiting corrosion at a surface in the production, transportation, storage, and separation of fluids such as crude oil and natural gas, the compounds having the formula:   

Thiol adducts for corrosion inhibition

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.

Preparation of new stable hydrogen sulfide scavengers useful in both water as well as oil medium applications

Disclosed are methods for preparing disulfide compounds through oxidative coupling of thiol compounds. Thiols are oxidized to the corresponding disulfide compound in high yield in presence of a base and a metal salt. The method uses low catalyst loadings and provides organic disulfide compounds with little to no byproducts.

Metal-catalyzed oxidative coupling of thiols

Disclosed are corrosion inhibitor compounds and compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed are methods of using the compounds and compositions as corrosion inhibitors, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.
