Although viscosity is the most commonly used parameter to assess the effectiveness of a lubricant, it alone does not predict functionality sufficiently, especially in field conditions. Inherent differences of the chemical composition of biobased oils greatly affect how they perform. Lubricity is another important parameter to consider in the determination of a lubricant's effectiveness. This article reports lubricity characteristics of selected vegetable oils, animal fats, and their derivatives, along with petroleum- and mineral-oil based lubricants for comparison purposes. The article also gives a compilation of fatty acid profiles of selected biobased oils, fats, and their derivatives. It was found that all of the biobased fats, oils, and their derivatives had better lubricities than #2 diesel fuel. All biobased oils and fats had a better lubricity than a turbine drip mineral oil (control). Crude vegetable oils had significantly better lubricities than their refined or transesterified (methylated or ethylated) forms. It also was found that the type of fatty acid (saturated or unsaturated) or its concentrations did not correlate with the lubricity value of a particular oil, fat or their derivatives.(Download PDF) (Export to EndNotes)
