Supercritical CO2 Extraction and Fractionation of Lavender Essential Oil and Waxes

Journal of Agricultural and Food Chemistry, 1995
Supercritical CO 2 extraction of essential oil from lavender was performed on a laboratory apparatus as well as in a pilot plant. A two-stage separation procedure was used to induce the fractional separation of the extracts. Detailed GC-MS analysis of the products was performed to assess the best extraction and the best separation conditions.

Temperature dependence of isotopic fractionation in CO2 photolysis

Chemical Physics Letters, 2009
Abstract The effect of temperature on the heavy isotope ratios of the products (CO and O 2 ) of photolysis of CO 2 by ∼185 nm photons was studied. The isotope ratios 18 O/ 16 O and 17 O/ 16 O in O 2 and CO and 13 C/ 12 C in CO increase with temperature by ∼1‰ per K. The increase in 17 O/ 16 O in O 2 is related linearly to the increase in 18 O/

Purification of sclareol by supercritical CO2 fractionation process

The Journal of Supercritical Fluids, 2017
Abstract The implementation and optimization of continuous supercritical CO2 fractionation of a clary sage extract containing 25 wt% of sclareol were performed in order to increase its sclareol content. After preliminary experiments confirming the feasibility of the process, different operating conditions were studied: CO2-over-feed mass ratio from ...

Evaluation of combining ultrapulse CO2 with fractional CO2 laser for the treatment of atrophic scars in Asians

Lasers in Medical Science
Various treatment modalities have been applied to atrophic scars. Fractional CO2 laser treatment has attracted increasingly more attention because of its quicker recovery time and fewer side effects. However, its limitation of sculpting the edge is an urgent shortcoming.
