DEVELOPMENT OF A BIOLUBRICANT FROM WILD OLIVE (Ximenia americana) SEED OIL.
The main goal of this research was to develop a biolubricant from Wild olive (Ximenia americana) seed oil through expoxidation process. Wild olive seed oil (WSO) with an iodine value of 150.0g /100g was expoxidised with hydrogen peroxide as oxygen donor in the presence of NaOH as a catalyst. The effect of temperature and hydrogen peroxide concentration on the physical properties of Expoxidised Wild olive Seed Oil (EWSO) were studied. The specific gravity range (0.83- 0.92) and surface tension range (42 dynes cm-1- 51 dynes cm-1) is in the range found for lubricant mineral oil. The flash point range (261OC -274OC) and pour point range (-150C to -20C) corresponds to that of lubricants from synthetic esters. The high dynamic and kinematic viscosities values obtained which exceed that of lubricants from mineral oil and synthetic esters at various temperatures suggest its potential application as a biolubricant. It could be concluded that it is possible to develop a biolubricant from a locally available renewable resources such as Wild olive (Ximenia americana) seed oil. Hence, EWSO could be a synthetic lubricant basestock.
