The presence of methyl ester is preferred because it functions as a foam supressant, diluent and amine scavenger during distillation.Type: ApplicationFiled: February 1, 2001Publication date: July 5, 2001Inventor: Larry W. Gatlin

Patent number: 6194361Abstract: A composition useful as a well lubricant, solvent and emulsifier that is preferably formed by the reaction and distillation of a tall oil fatty acid with a fatty alkanolamide, preferably in the presence of methyl ester of fatty acids, and most preferably when further reacted and distilled with an emulsifier such as coconut oil diethanolamide or distilled tall oil amide of AEP. The fatty acids and oils useful in the invention can range from C8 to C24, with C12, C14, C16, C18 and C20 fatty acids and oils being most preferred. The presence of methyl ester is preferred because it functions as a foam supressant, diluent and amine scavenger during distillation.Type: GrantFiled: May 14, 1998Date of Patent: February 27, 2001Inventor: Larry W.

Patent number: RE42313Abstract: Triglyceride oils having unsaturated fatty acid substituents are modified to convert sites of unsaturation to C-2 to C-10 diesters. The resulting derivatives are characterized by thermal and oxidative stability, have low temperature performance properties and are environmentally-friendly. They have utility as hydraulic fluids, lubricants, metal working fluids and other industrial fluids. The triglyceride oils are most easily prepared via epoxidized vegetable oils which are converted to the diesters in either a one- or two-step reaction.Type: GrantFiled: June 7, 2005Date of Patent: April 26, 2011Assignees: The United States of America as repesented by the Secretary of Agriculture, The Penn State Research FoundationInventors: Sevim Z. Erhan, Atanu Adhvaryu, Zengshe Liu
