Busting the Myth : A Scientist’s Take on Butane Hash Oil vs. CO2 Extraction. CO2 is a better extraction for the terpenes in the hemp: The beta-pinine, Cineole, linalool, alpha-terpinol and bornelole.
Supercritical fluid extraction
The supercritical CO2 fluid is used as the separation medium,so as to achieve efficient separation of specific components in the raw materials.
Among several supercritical fluid (abbreviated SCF) technologies, the earliest developed, most researched and industrialized product technology is undoubtedly the supercritical fluid extraction (abbreviated SFE) technology.
Supercritical CO2 extraction (SFE) Supercritical carbon dioxide extraction has the advantages of high selectivity to solutes and low operating temperature, which can avoid thermal damage and no solvent residues. In addition, carbon dioxide has the advantages of safety, non-toxicity, non-reactivity… Read more »Supercritical CO2 fluid fractionation technology (SFF)
Preparation before starting: First check whether the power supply and three phases are intact. (220V/60HZ) Add 30% ethylene glycol + 70% pure water to the water tank in the refrigerator. (Chloride ion content <25mg/L), and connect the cooling water pipe… Read more »Operation Manual of Supercritical Fluid Fractionation Unit
Forewords It is generally believed that solid solutes are physically, chemically or mechanically immobilized on a porous substrate. Four steps Many scholars believe that for supercritical CO2 extraction of natural products, the following four steps can be used to describe… Read more »Factors affecting mass transfer in supercritical CO2 extraction
In order to improve the extraction ability and selectivity of target solutes by CO2, add an appropriate amount of non-polar or polar solvents to utilize co-solvents.
Foreword Supercritical fluid extraction is a new type of extraction and separation technology. It uses a supercritical fluid, that is, a fluid in a thermodynamic state at a temperature higher than the critical temperature and a pressure higher than the… Read more »Supercritical fluid extraction separation technology
