A composition useful as a well lubricant, solvent, emulsifier, and performance extender for corrosion inhibitors in high velocity gas, oil or water drilling, production or gathering applications, 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 aminoethylpiperazine. 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 suppressant, diluent and amine scavenger during distillation.
A composition formed by the reaction of, and removal of distillates from, a mixture of:
A composition comprising from about 45 to about 90 weight percent of the reaction product of tall oil fatty acid and a fatty alkanolamide, reacted in the presence of from about 5 to about 25 weight percent methyl ester of fatty acids, then further reacted and distilled in the presence of from about 5 to about 30 weight percent of the reaction product of a fatty oil with an alkanolamine.
A composition comprising a reaction product having the following structural formula:
A composition comprising the reaction product of:
A method for making a lubricant composition comprising the steps of:
A composition made by combining a tall oil fatty acid with a fatty alkanolamide, a methyl ester and a mixture of coconut oil and diethanolamine inside a stirred, vented reactor, thereafter heating to a temperature ranging between about 320° and 350° F. and maintaining such temperature for about 6 to 8 hours, while venting distillates occurring at such temperatures.
A composition made by combining distilled tall oil with a fatty alkanolamide, a methyl ester and a corrosion inhibitor that is the reaction product of distilled tall oil with aminoethylpiperazine inside a stirred, vented reactor, thereafter heating to a temperature ranging between about 320° and 350° F. and maintaining such temperature for about 6 to 8 hours, while venting distillates occurring at such temperatures.
A composition made by combining distilled tall oil with a fatty alkanolamide, a methyl ester and a 50/50 mixture of coconut oil and diethanolamine inside a stirred, vented reactor, thereafter heating to a temperature ranging between about 320° and 350° F. and maintaining such temperature for about 6 to 8 hours, while venting distillates occurring at such temperatures.
A composition comprising a reaction product having the following structural formula:
