Abstract
AbstractThe solubility of jojoba oil in dense carbon dioxide has been investigated by a dynamic method between 100 and 2600 bar and at temperatures within the range 20 to 80° C. The solubility isotherms and isobars of jojoba oil are compared with those of soybean oil. The appearance of solubility maxima was demonstrated for both cases in the high pressure region. The results are discussed and their implications for preparative extraction pointed out. In order to optimize the precipitation conditions a study was made of the solubility of cuticular wax in the low pressure region as a function of temperature and this was compared with the behaviour of typical essential oil components. The available differences can be utilized for an effective preprecipitation of wax from essential oils.
