| titleOfInvention | Polyion liquid inhibitor and preparation method and application thereof |
| abstract | The invention provides a polyion liquid inhibitor and a preparation method and application thereof, wherein the polyion liquid inhibitor is obtained by copolymerizing acrylate and 1-vinyl-3-alkyl imidazole bromide. The obtained polyion liquid inhibitor can improve the fluidity of wax oil in the artemisinin-containing extract, and can remarkably inhibit the co-precipitation of the wax oil and the artemisinin in the crystallization process by reducing the freezing point of the wax oil, so that the purity of the finally obtained artemisinin product is improved; moreover, the polyion liquid inhibitor can be recycled, and the problems of poor separation effect, complex process and the like in the artemisinin purification process are solved. |
