Title:
METHOD FOR SELECTIVELY OXIDIZING STYRENE IN WATER
Document Type and Number:
WIPO Patent Application WO/2024/000825
Kind Code:
A1
Abstract:
The present application relates to a method for selectively oxidizing styrene in water. The method comprises: adding styrene, a catalyst and an oxidizing agent to a reaction solvent, performing an oxidation reaction at 25-55°C, and filtering the resulting product after the oxidation reaction is completed, so as to obtain a filtrate, wherein the reaction solvent is water; the oxidizing agent is cumyl hydroperoxide or a hydrogen peroxide solution; and the catalyst is polymanganese porphyrin. The reaction solvent for the oxidization of styrene is water, which replaces a conventionally used organic solvent. The method is safe, inexpensive, non-toxic and pollution-free, and conforms to the modern concept of green chemistry; and the polymanganese porphyrin catalyst is used in combination with an oxidizing agent, such that a selective catalytic reaction is efficiently carried out in a water solvent. The system has short reaction time, a high conversion rate, and relatively high selectivity.
