| titleOfInvention | A kind of preparation method of special chromatographic separation medium for cannabidiol separation |
| abstract | The invention relates to a preparation method of a chromatographic separation medium specially used for the separation of cannabidiol, characterized in that the specific steps are: (1) adding elemental bromine into an organic solvent containing a certain number of moles of cannabidiol, and stirring; (2) Add the porous amino silicon spheres into the above organic solvent, stir, heat for 24 hours, filter; (3) place the bonded silicon spheres in the organic solvent again, add an appropriate amount of pentafluorophenylacetic acid, stir, and mix evenly , then add the catalyst, heat the reaction for 24h, and filter; (4) repeatedly wash with organic solvent and dry to obtain chromatographic separation medium. The chromatographic separation medium bonded with two groups of the present invention is superior to bonding a single group in terms of bonding density and separation selectivity, and especially has better separation performance for aromatic compounds and their derivatives. |
