Title:
PRODUCTION OF PHENOL AND METHYL ETHYL KETONE
Document Type and Number:
Japanese Patent JPH05178772
Kind Code:
A
Abstract:
PURPOSE: To efficiently obtain the subject compounds in high yield without lowering the yield of sec-butylbenzene hydroperoxide by recycling sec- butylbenzene without containing styrenes to an oxidation step.
CONSTITUTION: A recovered reactional solution produced after oxidizing reaction of sec-butylbenzene is subjected to reducing reaction with hydrogen to convert the styrenes in the reactional solution into alkylbenzenes. The sec-butylbenzenes substantially without containing the styrenes are recycled to the oxidation step to afford the objective compounds.
