    摘要: The present disclosure provides an ionic liquid produced from a renewable source and with excellent lubricating properties, and methods of making the same. The ionic liquid includes an anion salt of at least one of a fatty acid, a rosin acid, or derivative thereof. The method for making the ionic liquid or lubricant composition of the present disclosure includes admixing a cation and an anion in a ratio of about a 1.5:1 to about 1:1.5 at room temperature to form a reaction mixture, wherein the anion comprises at least one of a fatty acid, a rosin acid, derivative thereof, or a combination thereof, and the cation comprises at least one of choline, imidazolium, pyridium, pyrrolidinium, ammonium, phosphonium, sulfonium, derivatives thereof, or combinations thereof; maintaining the reaction mixture at a pH of about 6 to about 9; and drying under reduced pressure to yield a lubricant including an ionic liquid.
