| titleOfInvention | Improve oxidation of cumene |
| abstract | The present invention relates to the method utilizing oxygen-containing gas oxidation of cumene to be become cumene hydroperoxide, the method comprises first oxidation reactor at least in a series of 3-8 reactor by cumene charging and oxygen-containing gas charging introducing, thus formation oxidation mixture, and oxidation mixture is introduced at least one subsequent reactor from an oxidation reactor, wherein under the condition of the liquid level reduced, operate reactor; Be oxidized as dry oxidation, thus the only gas feed introducing oxidation reactor is cumene charging and oxygen-containing gas charging; With caustic alkali, then wash oxygen-containing gas charging with water, to remove all acidity or alkaline trace thing before it is introduced oxidation reactor; Pressure range in each oxidation reactor is at 0-10barg; Be separated and cool the discharge gas at the top from each oxidation reactor, thus forming the condensation product comprising unreacted cumene, and washing condensation product it is recycled at least the first oxidation reactor at least partially; The discharge gas do not condensed is processed in thermal oxidizer; And the liquid stock of the first reactor in oxidation reactor series 30-300% more than residue reactor, preferred 50-100%, or the liquid stock of initial two reactors in oxidation reactor series 30-300%, preferred 50-100% more than residue reactor. |
