Abstract

The invention belongs to the technical field of a polymeric microsphere surface immobilized N-hydroxyphthalimide catalyst and specifically relates to a preparation method of a crosslinked polystyrene microsphere surface synthesized and immobilized N-hydroxyphthalimide catalyst. According to the preparation method, chloromethylated crosslinked polystyrene microspheres CMCPS are immersed in a de-watering solvent to undergo swelling so as to prepare modified microspheres CPS-PA with the surface bonded with phthalic anhydride; and then, the modified microspheres CPS-PA with the surface bonded with phthalic anhydride is used to prepare crosslinked polystyrene microsphere surface synthesized and immobilized N-hydroxyphthalimide. The method provided by the invention has advantages as follows: good stability, simple process, convenience in operation and high immobilization capacity. The product is easy to separate in a catalytic oxidation system and has good reusability, and the system is easy for purification.

Description

technical field

[0001] The invention belongs to the technical field of N-hydroxyphthalimide catalysts immobilized on the surface of polymer microspheres, and specifically relates to a method for synthesizing and immobilizing N-hydroxyphthalimide on the surface of cross-linked polystyrene microspheres. Process for the preparation of amine catalysts. Background technique

[0002] The transformation of hydrocarbons into oxygenates and alcohols into deep oxides plays an extremely important role in the chemical industry. However, the traditional oxidation process generally uses stoichiometric strong inorganic oxidants, which brings serious environmental problems. From the perspective of green and sustainable chemistry, catalytic oxidation using oxygen or atmospheric oxygen as an oxygen source is a clean and economical organic synthesis route, which has been vigorously researched and developed in recent years. Using molecular oxygen to realize the oxidative transformation of org...
