A soxhlet extraction was used for the extraction of the oil and the solvent used was hexane. The FTIR analysis of the castor oil extracted was carried out. A typical spectrum of castor oil range between (4500–400 cm−1), using 100 μm BaF2 transmission cell. This spectrum illustrates the dominant spectral features associated with the oil absorption regions: Absorption at (4336.12 cm-1) impurities. The OH stretching absorption of an alcohol (3650-3250 cm-1), the CH stretching absorption in region from (2980–2850 cm−1), the functional group CNO stretching absorption range from (2350-2000 cm-1), the -C=O stretching absorption of the triglyceride ester linkage around (1850–1650 cm−1), the CH3 bending (twisting) is at (1447- cm-1), the CH3 bending (wagging) is at (1390-1370 cm-1), the –COC bending is at (430-450 cm-1) vibration and out of the plane bending vibration of cis-disubstistuted olefins and the absorption band range from (1120-1110 cm-1), overlapping of the CH2 rocking vibration and the out of plane vibration of cis-disubstituted olefins and the absorption range from (740-720 cm-1). Physicochemically, the seed oil extracted was yellowish in color, with an oil content of 30.02 ± 0.02 % and Viscosity (1000C) at 9.34, Viscosity (400C) at 63.89. Viscosity index (125) and Pour point (24OC). This investigation suggests the seed oil can be used for fuel and other industrial purposes.
