Supercritical CO2 Extraction of Essential Oil From Yarrow

The Super Critical fluid technology is a new-type separation technology in modern chemical separation. TheSuper Critical extraction takesCO2 as the solvent. AsCO2 fluid under Super Critical state has larger density anddielectric constant, larger dissolvability against substances, which can change abruptly when pressure and temperaturechange therefore it has not only the selection of dissolvability against some substances, the separation of the solventwith the extracted substances is also easily. The Super CriticalCO2 extraction is specially suitable for extraction offat-soluble and heat sensitive substances with high boiling point, and is suitable for fine separation of differentcomponents, i.e. Super Critical fine distillation.
TakeCO2as the solvent to make extraction and purification upon a lot of products such as biological productsfoodstuff and medicines.

1. Low Critical temperaturesuitable for extraction and purification of heat sensitive compound.
2. Being capable to provide inert environment to avoid oxidation of products and affection of effectivecontent of extracts.
3. Fast extraction speed, no toxicity, non-flammable, safe application and no pollution upon Environment.
4. No residue of solvent, no nitrate and ions of heavy metal.
