| titleOfInvention | A kind of preparation method of isoprenyl isopentenyl ether |
| abstract | A preparation method of isoprenyl isopentenyl ether, the method uses a rectifying tower provided with a nitrogen mixing device for mixing and stripping a reaction solution with nitrogen at the bottom, and the method is used for the rectifying tower from the bottom of the rectifying tower. The produced material is flashed, and a part of the distilled inhibitor is used as a flushing medium, and the other part is recycled. The method of the invention can significantly reduce the residence time of isoprenyl isopentenyl ether under high temperature conditions, thereby reducing the amount of heavy components produced, and can also realize on-line cleaning of the column internals, reducing the amount of polymer on the column internals. accumulation. |
