Fractionation of olibanum Resin using Supercritical Carbon Dioxide

摘要

A process for extracting essential oil from sequentially, incensole and boswellic acid from olibanum resin,Understanding the stages of the procedure: (a) Crush olibanum Resin; (b) Separating a First fraction of Essential Oil with liquid carbon dioxide to a First temperature QEU varies between 0 Deg and 30 deg C and a pressure of between 40 and 60 bar bar with soft or supercritical carbon dioxide.And with a First Flow that varies between 10 and 400 g of Crushed material g / kg / min until you can no longer Recover more essential oil or extract yield is lower than 0.1% of initial Mass per hour; (c) recover Essential Oil separator; (d) Separating a fraction of Second Derivatives of incensole with Supercritical Carbon Dioxide to a Second temperatureVaries between 31 and 100 deg C and a pressure of at least 72 Second,8 bar and a Second Flow that varies between 10 and 400 g of Crushed material g / kg / min until you can no longer Recover more incensole or their Derivatives or the extract yield is lower than 0.1% of initial Mass per hour; (e) recover from incensole optionally separator; (f)Continue the process of Separation with Supercritical Carbon Dioxide to other sets of temperature and / or pressure increasing until they separated fractions most desired; (g) to separate a fracciu00f3Additional boswellic acid in Supercritical Carbon Dioxide at a temperature of at least 31 deg C and a pressure of at least 728 bar and to a Flow that varies between G and 400 g / kg / min using a cosolvent Crushed material at a level that varies between 0.05 and 50% in volume.0% in volume of flow of CO2 until it achieves complete separation of boswellic acids or determines that it can extract more materials or the extract yield is lower than 0.1% of initial Mass per hour; (H) recover boswellic acid of the separator and remove the cosolvent by Evaporation or Distillation; Optionally,Continue the process of Separation with Supercritical Carbon Dioxide to another set of pressure and temperature and cosolvent until they separate all the desired fractions; (j) to recover the resCough not remaining separate.
