ABSTRACT: In this study, with borneol fragments in the
crystallized mother liquor of natural borneol used as the raw materials,
supercritical carbon dioxide method is adopted for refining to get high purity
borneol. The result of the experiment shows that the yield and purity are
excellent with an extraction pressure of 11 MPa, an extracting temperature of 40°C, a
carbon dioxide flow rate of 25 L·h-1 and an extraction time of 20 minutes. After detected by gas
chromatography, the purity of the crystallization products could reach 96%.
