Abstract

The paper presents a report on the physico-chemical properties and lubricity grade of refined Dika nut oil for use as lubricant, in consonance with sustainable technological development for vision 20:2020. Chemical properties such as iodine, acid and saponification values of the oil were evaluated. The physical properties of the oil were characterized in terms of its density, viscosity at 40 and 100oC, flash and pour points. The lubricity of the oil was estimated on the basis of its viscosity, comparing with Society for Automotive Engineering (SAE) oil grades. Test results showed that the oil has the following physical properties: viscosity of 57.57 cSt at 40oC and 6.78 cSt at 100oC; viscosity index of 71; flash point of 296oC; cloud point of 37oC; pour point of 32oC; and specific gravity of 0.928 at 15oC. The chemical properties in terms of its oxidative stability, saponification, acid and iodine values were 250 hours, 199.72 mgKOH/g, 0.3 mgKOH/g and 0.518%, respectively. The viscosity of the oil at 40 and 100oC ranked between SAE 20 and 30 lubricating oil at both temperatures. The oil, thus, shows a strong potential for use as lubricant.
