Distillate cbd from hemp
Cbd extracted substance is made through distillation of hemp, which is selective distillate and separation from mixtures. The distillation method is suitable for substances with strong volatility. Since the boiling point of CBD is more than 400 degrees at normal temperature and pressure and it is insoluble in water, the extraction method is the most suitable extraction method.
Three ways to extract cbd from hemp
There are several ways to extract cbd from hemp, and the three most popular ways and their advantages and disadvantages are as follows:
1. Organic solvent extraction
The main advantages of this way are easy to operate. It has low requirements on equipment and low energy consumption. The disadvantage is that organic solvents (such as ethanol) are dangerous and liable. The solvent solubility is fixed, and may occur environmental pollution. Chlorophyll or other harmful substances may also be produced.
2. Supercritical carbon dioxide extraction
The main advantage lies in the wide separation range, and the adjustment of the dissolution ability of the extractant can be realized by changing the temperature and pressure, but the equipment and technical requirements are high, the energy consumption is large, and the instrument cleaning is difficult.
3. Olive oil extraction method
This method is very safe and low cost. Using this method to obtain the CBD basically does not fail. However, the oil is highly perishable and needs to be stored in a cool, dark area and used as soon as possible, and the production capacity is too low, which is not suitable for commercial extraction.
