| abstract | (57) [Summary] [PROBLEMS] To efficiently remove phenol, acetone and α-methylstyrene by suppressing by-products of high boiling compounds and hydroxyacetone in the decomposition of cumene oxidation products containing cumene hydroperoxide as a main component. It is intended to provide a method for obtaining the same. A method for producing phenol, acetone and α-methylstyrene by a two-step reaction by decomposing a cumene oxidation product containing cumene hydroperoxide as a main component, comprises a compound represented by a structural formula H 8-n (XM 12 O 40). (Where X is P or Si, M is Mo or W, and n is 4 or 5) Indicates an integer. ) In the presence of heteropolyacids A cumene oxidation product containing cumene hydroperoxide as a main component is supplied to the first-stage reactor, and the reaction temperature is 55 to 90 ° C. And maintaining the acetone concentration in the reaction mixture at 20 to 70% by weight and the conversion of cumene hydroperoxide to 95 to 9%. The reaction was carried out to 9.9% and then the reaction temperature was 55-120. A process for producing phenol, which comprises completing the reaction in a second-stage reactor at a temperature of ℃. |
