Patent number: 10988689Abstract: Disclosed herein are sulfur-functional tall oil compositions, referred to herein as S-TO compositions. The S-TO is a sulfur-functional tall oil fatty amide composition, or sulfur-functional tall oil phosphate ester composition. Also disclosed herein are S-TO concentrates, which are stable and do not degrade to form H2S under standard storage conditions for a period of 1 day to 5 years. Also disclosed herein are treated water sources and treated metal containments including one or more S-TO compositions. The S-TO compositions inhibit corrosion of a metal containments contacted with one or more water sources, wherein the one or more water sources comprise one or more corrodents. The S-TO compositions are as effective or more effective at inhibiting corrosion than conventional sulfur-based corrosion inhibitors when compared on a weight basis.Type: GrantFiled: October 30, 2018Date of Patent: April 27, 2021Assignee: ChampionX USA Inc.Inventors: Jeremy Moloney, Prakasa Rao Anantaneni

Patent number: 8901245Abstract: Methods for forming rosin-derived cationic compounds are provided. The method can include attaching a cationic group to a conjugated diene on a hydrophenathrene-based ring of a resin acid (e.g., levopimaric acid, abietic acid, dehydroabietic acid, or a mixture thereof) to form a rosin-derived cationic compound. Attaching the cationic group to the conjugated diene on the hydrophenathrene-based ring of the resin acid can be achieved via a Diels-Alder reaction of a dienophile with the hydrophenathrene-based ring of the resin acid. Rosin-derived cationic compounds are also provided. The rosin-derived cationic compound can include a cationic group attached to a conjugated diene on a hydrophenathrene-based ring of a resin acid, wherein the rosin-derived cationic compound further comprises a carboxylic acid group.Type: GrantFiled: December 10, 2013Date of Patent: December 2, 2014Assignee: University of South CarolinaInventors: Chuanbing Tang, Jifu Wang, Alan W. Decho, Yung Pin Chen
