Synthesis and Characterization of Dealuminated Ultra-Stable Zeolite Y Supported Cesium Salt of Phosphotungstic Acid for the Esterification of Acrylic Acid with Butanol

Synthesis and Characterization of Dealuminated Ultra-Stable Zeolite Y Supported Cesium Salt of Phosphotungstic Acid for the Esterification of Acrylic Acid with Butanol

Wastewater containing 10–20 wt% of acrylic acid (AA) is released from petrochemical industries during the manufacture of AA, acrylic ester, water-soluble resin and flocculants. This untreated wastewater could have detrimental effects on the environment due to its high chemical oxygen demand. Heterog...
