Method of purifying cumene hydroperoxide decomposition products from hydroxyacetone and from other carbonyls |
摘要 |
Purification of cumene hydroperoxide cleavage products from hydroxyacetone and carbonyl compounds is accomplished via extraction of hydroxyacetone and carbonyl compounds from cleavage products with a circulating water-salt solution in an extractor during an extraction stage and subsequent conversion of hydroxyacetone and other carbonyl compounds into deep condensation products in a HAC reactor operating as a plug-flow reactor or mixing reactor or as their combination. The conversion/condensation process is conducted in the water-salt solution by treating the hydroxyacetone and carbonyl compounds with alkaline agents. Various homogenous and/or heterogeneous alkaline catalysts may be used. Optionally multiple sequential extraction stages may be connected to the HAC reactor for improved performance.
