Effect of Temperature on Extraction of Castor Oil from Castor Seeds Using Potential Green Solvents ()
ABSTRACT
Extraction
of castor oil from castor seeds was investigated using different green solvents
which include d-limonene, p-cymene, α-pinene, ethanol, and furfural at the temperature range of (323 - 413) K. The Soxhlet extraction method was employed to investigate the effect of temperature at
atmospheric pressure. The focus of the
study was to investigate a potential green solvent that can produce the
high yields compared to the traditional solvent (hexane). The results show that
at the average time of 3 hours and 30 minutes, the castor oil yield for green solvents were ranked as furfural
(47.13%) > ethanol (45.37%) > p-cymene (39.15%) > d-limonene
(39.13%) > α-pinene (38.11%).
These castor oil yields were obtained at optimum temperatures for each green
solvent. The castor oil yields were compared to the yield of hexane (31.36%) at
same average time. The green solvents were recovered by using simple
distillation, except furfural which was difficult to be recovered.
