Method for preparing phase transfer catalyst and method for preparing 5-membered ring carbonate compound using catalyst prepared by this method

摘要

In the present invention, the polystyrene-based polymer support by polymerizing 55-89 parts by weight of styrene and 1-20 parts by weight of divinylbenzene, by adding 10-40 parts by weight of vinylbenzene chloride to the partial polymer obtained in step (a) Forming a support, and supporting the support with a halogenated trialkylbenzylammonium (R ₃ -benzylammonium-X: the alkyl group (R) is an alkyl group having 2-8 carbons, X is Cl or Br) Using a process for producing a phase transfer catalyst comprising a, and the phase transfer catalyst prepared by this method, by reacting the carbon dioxide and epoxide derivatives for 2 to 24 hours at a normal pressure of 50 to 120 ℃ to prepare a five-membered ring carbonate compound A method is provided. According to the present invention, the recovery and reuse of the catalyst is easy and the five-membered ring carbonate can be produced in a high yield in a relatively short time.
