Abstract
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. 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.
Claims43
A composition formed by the reaction and removal of distillates from a mixture of a tall oil fatty acid having from 8 to 24 carbon atoms, an amide/ester, a methyl ester of fatty acid, and an emulsifier.
A well lubricant composition comprising from about 45 to about 90 weight percent of the reaction product of tall oil fatty acid and a fatty alkanolamide, when 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 having the following structural formula:
- 4
- wherein R1 is selected from the group consisting of distilled tall oil and coconut oil;
- R2 is selected from the group consisting of low rosin tall oil, vegetable oil and distilled tall oil;
- and R3 is selected from the group consisting of vegetable oil, vegetable extract, tall oil and distilled tall oil.
A well lubricant composition comprising from about 60 to about 90 weight percent of the reaction product of distilled tall oil and a fatty alkanolamide, which is further reacted and distilled in the presence of from about 10 to about 20 weight percent of the reaction product of distilled tall oil and AEP.
A method for making a lubricant composition comprising the steps of:
- combining and mixing inside a stirred reactor vessel in fluid communication with a condenser from about 55 to about 90 weight percent of a mixture of fatty acids and amide/ester wherein the ratio of fatty acid to amide/ester ranges from about 2:1 to about 3:2, from about 5 to about 30 weight percent of an emulsifier and up to about 25 weight percent of a methyl ester of fatty acid;
- gradually increasing the temperature of the reactants above 3000 F. while stirring;
- maintaining the temperature of the reactants at a reaction temperature above about 300° F. with stirring for a period of from about 6 to about 12 hours while removing distillate from the reactants;
- and thereafter recovering the undistilled reaction product remaining inside the reactor.
