Abstract: In recent years, Dialkoxyl substituted p phenylene vinylene polymer (PPV) photoluminescent function materials were widely applied in LED(LCD) TV, and computer, electrical equipments and aircraft color LED(LCD) displays. In this work, we used different catalysts to synthesize dialkoxyl substituted PPV photoluminescent function materials intermediate of 4-butyloxyphenol by phase transfer catalytic reaction. 4-Butyloxyphenol was synthesized using hydroquinone and butyl bromine in toluene solvent in the presence of sodium hydrate, by using different phase transfer catalyst. The product's yield was over 90% under the reaction temperature of 60~65 ℃ and the reaction time of 3.0 h. The different catalysts and reaction times were optimized and discussed. The structures of products were characterized by FTIR and NMR spectroscopy.

Key words: 4-butyloxyphenol, phase transfer catalysis, synthesis, hydroquinone, butyl bromine
