| titleOfInvention | A kind of method for separation and purification of cannabidiol |
| abstract | The invention discloses a method for separating and purifying cannabidiol. The mother liquor containing cannabidiol is loaded into a chromatographic separation column containing a solid adsorption material, eluted with an eluent, the eluent is collected, and the eluent is Evaporative crystallization, that is. The particle size of the solid adsorbent material is 5-50 μm, the specific surface area is 400-1000 m 2 /g, the pore diameter is 80-1000 A, and the pore volume is 0.6-1.2 cm 3 /g. Advantages: (1) The present invention has low requirements for equipment, and is controlled within 3Mpa, which provides the possibility for industrialization; and the separation efficiency is high, and the purity of cannabidiol is higher than 99.5%; It is more convenient to remove impurities by adsorption resin. (3) Using polymer materials, it is more resistant to acid and alkali. (4) The amount of the eluent is less, and when the flow rate of the eluent is 0.3 BV/min, all 6 column volumes can elute the cannabidiol. |
