摘要： A method of inhibiting, preventing, reducing, and/or reversing sulfur plugging which comprises treating sulfur-containing fluids in oil and gas wells, such as petroleum (and/or fluids containing a component which converts to sulfur), with a reactant compound capable of combining with sulfur to produce products which are soluble or dispersible in the sulfur-containing fluids. This process is illustrated by the use of olefins as the reactive compound, and more particularly by the use of an olefin capable of reacting with sulfur to form 1,2-dithiole-3-thiones.

摘要： Silicon-containing aminomethyl, or substituted aminomethyl, phosphonic acids and derivatives thereof. The silicon atom is silicone functional (i.e., has a -SiO- group) and is also attached to an alkyleneamino group which may have one or more amino groups (i.e., an alkylene-amin group having at least one NH group) capable of reacting with a carbonyl compound (i.e., aldehyde or ketone) and phosphorous acid, or a derivative thereof, to form aminomethyl phosphonic acid. All, or less than all, of the N-H groups may be converted to aminomethyl phosphonic acids. The silicon-aminomethyl phosphonic acids may be monomeric, polymeric, or copolymeric. They are useful, for example, as corrosion inhibitors, scale inhibitors, water clarifiers and for other uses.
