Method for extracting and separating 24-dehydrocholesterol and cholesterol by ionic liquid |
| abstract |
The invention discloses a method for extracting and separating 24-dehydrocholesterol and cholesterol by ionic liquid. According to the invention, ionic liquid or binary mixed solvent made of ionic liquid and polar solvent is used as extractant; extract and raffinate are obtained through fractional extraction; and high-purity 24-dehydrocholesterol and cholesterol can be obtained from the extract and the raffinate respectively. The ionic liquid extractant adopted by the method has better thermal stability, noninflammability and higher selectivity than traditional organic solvent, and has the characteristics of simple and safe technology, environmental friendliness and the like, so that the ionic liquid extractant is suitable for industrial production. |
