Leaching of Jojoba Oil

Abstract

The leaching process was applied to extract jojoba oil by means of Multifunctional Extraction Plant which presents in Specialized Training Institute for Chemical Industries (STICI).Three solvents were examined; n-hexane, diethyl ether, and petroleum ether.The purpose of work is to select the best solvent which extracts more oil and comparing among them according to cost and energy consumption during the leaching operation.The results of our study indicate that the best solvent was n-hexane; which the jojoba oil leached using this solvent was the largest amount. The n-hexane also the less one has consumed the energy.The other purpose is to study the relationship between seeds' particle size and the oil yield; therefore, two different particle sizes of jojoba seeds were employed. From the smaller one we get highest oil yield.
