Abstract
The Physicochemical properties of the extracted oil from Raffia palm (Raphia regalis) were investigated. Physical properties such as refractive index, specific gravity, viscosity, moisture content, flash point, smoke point, fire point, pour point and cloud point; and chemical properties such as acid value, free fatty acid, saponification value, unsaponifiable matter, iodine value, ester value and peroxide value were investigated for both raw Raffia oil and transesterified raffia oil. The various properties were investigated using ASTM standard methods and calculations. Results obtained for physical properties: refractive index, specific gravity, viscosity, moisture content, flash point, smoke point, fire point, pour point and cloud point were 1.437, 0.765, 1.420 mm2/sec, 8.0%, 154ºC, 140ºC, 160ºC, -3ºC and -7ºC respectively for the raw Raffia oil, and 1.341, 0.840, 1.21 mm2/sec, 1.6%, 70ºC, 66ºC, 72ºC, -5ºC and -12º for the transesterified raffia oil. Results for the chemical properties: acid value, free fatty acid, saponification value, ester value obtained in (mgKOH/g), iodine value (mgI2/g), peroxide value (mEq/kg) and unsaponifiable matter (%) were determined to be, 18.849, 9.472, 136.043, 117.194, 5.076, 192.000 and 1.814% respectively for the raw Raffia oil; and 31.977, 16.069, 193.545, 161.568, 167.50, 350.800 and 2.481% for the transesterified raffia oil. It was concluded that Raffia oil when processed have great potentials for use as alternative fuel for energy generation.
