| titleOfInvention | Method for preparing phenol and acetone by acid catalyzed separation of cumene hydroperoxide |
| abstract | Homogeneous acid catalyzed separation of cumene hydroperoxide is typically carried out in such a way that a portion of the separation product is recycled and mixed into the feed stream to separate in a plurality of continuously arranged tube-bundle heat exchangers. The ratio of the circulated stream to the feed stream is from 10 to 25.n n n According to the invention, as the circulation ratio is reduced to a value below 10, surprisingly the selectivity increases significantly.n n n n Acid catalyzed separation, cumene hydroperoxide, acetone, phenol, tube bundle heat exchanger, circulation stream, feed stream. |
