ABSTRACT

Mineral oil-based lubricants are non-renewable, harmful to health and prone to price fluctuations. Thus, vegetable oils are considered as suitable alternatives to mineral oils for lubricant production. Research on the use of non-edible vegetable oils for lubricant development has become necessary. In this study, the oil extracted from mahogany (Khaya senegalensis) seeds was investigated as a feedstock for the production of bio-lubricant. The oil was extracted from the seeds using the traditional method. The oil was characterized, modified for suitability and used to develop lubricants for industrial applications. Commercially available mineral oil based lubricant SAE 20/W50 was used as a control. The acid value, free fatty acid, density and viscosity of the oil were then determined. The acid value, free fatty acid, density and viscosity of the oil obtained were 3.87 mgKOH/g, 2.46%, 0.936 g/cm3 and 9.5 cSt respectively. The characterisation of the oil produced revealed that the acid value, viscosity, flash point and density were within the standard specified by the ASTM. This is an indication that oil obtained from Khaya senegalensis oil could be used as feedstock for bio-lubricant production.
