Synthesis and characterisation of hydrophobic catalyst – Cs salt of 12-phosphotungstic acid functionalised dealuminated usy for the esterification of acrylic acid with butanol

Research and development work of acrylic acid (AA) recovery from petrochemicals industries effluent has been extensively carried out to minimize the production cost as well as to save the environment from any impacts of its high COD level. Esterification in reactive distillation column is one of the...
