CATALYSEUR POUR LA PRÉPARATION D'ÉTHER PHÉNYLIQUE DE PROPYLÈNE GLYCOL ET PROCÉDÉ DE SYNTHÈSE D'ÉTHER PHÉNYLIQUE DE PROPYLÈNE GLYCOL

摘要

Disclosed is the use of a quaternary phosphonium salt compound as a catalyst for preparing a catalyst for propylene glycol phenyl ether. Also provided is a method for synthesizing propylene glycol phenyl ether by mixing phenol and a quaternary phosphonium salt compound, and then adding propylene oxide under oxygen-free conditions, wherein the phenol is polymerized with the propylene oxide to produce the propylene glycol phenyl ether. The propylene glycol phenyl ether thus prepared has few impurities and contains no metal ions, such as potassium and sodium, and does not require subsequent operations to remove metal ions and perform rectification separation, thereby reducing the costs and allowing same to be directly applied to high-standard industrial production.
