| titleOfInvention | A kind of method that improves the yield of m-dicumene oxidation to prepare resorcinol |
| abstract | The invention provides a method for improving the yield of resorcinol prepared by the oxidation of m-dicumene. The method is to neutralize the sulfuric acid in the decomposed solution by adding organic amines in the decomposed solution containing resorcinol obtained by secondary oxidation and acid catalytic decomposition of m-dicumene, thereby avoiding the need for traditional sulfuric acid to neutralize the lye. The loss of resorcinol is a serious problem. The method further conducts alkaline extraction, neutralization and stripping of the hydroperoxide intermediate DHP and by-products generated after the primary oxidation of m-dicumylbenzene, and at the same time, the effect of pH value on the effect of stripping DHP was explored. Influence, to achieve the ability to precisely control the processing of intermediate products, thereby facilitating the subsequent secondary oxidation and the significant increase in the yield of resorcinol. |
