Oxidation of Hexanol to Hexanoic Acid over SiO2 Supported Peroxotungsto-phospho-quaternary Ammonium Catalyst System

Abstract

Abstract: The factors influencing the catalytic properties for the oxidation of hexanol to hexanoic acid over SiO₂ supported peroxotungsto-phospho-quaternary ammonium catalyst were investigated.The catalysts were characterized by means of IRand BETtechniques.The influence of different reaction conditions such as reaction temperature, reaction time, amount of hydrogen peroxide and catalyst was discussed for the oxidation reaction.The optimal reaction conditions were given.SiO₂ supported POWPcatalysts are obviously superior to the unsupported POWP under the same reaction condition.

Key words: Peroxotungsto-phospho-quaternary ammonium catalyst, n- Hexanol, n-Hexanoic acid, Catalitic oxidation
