| dc.description | The use of vegetable oil for lubrication dated as far back as 1650 BC. Art decorations on the inner wall of the Egyptian tomb of Tehuti-Hetep indicate that the olive oil on wooden planks was used to facilitate the sliding of large stones, statues and building materials (Shubkin, 1993). During the second world war, vegetable oils were used for lubrication because there was shortage of mineral oil. Different railway companies used mineral lubricants compounded with 7 por ciento -25 por ciento vegetable oil (Odi-Owei, 1998). The oil embargo of 1974 and subsequent escalation of petroleum prices brought a new urgent need for conservation of oil reserves and development of alternative raw material (Shubkin, 1993). In the 90s, research in vegetable oil lubricants was driven by environmetal concerns. The increasing demand for environmentally acceptable lubricant has led researchers to look to vegetable oils as an alternative. | |
