Kinetic Studies of the Esterification of Pure and Dilute Acrylic Acid with 2-ethyl Hexanol Catalysed by Amberlyst 15

The untreated waste water containing acrylic acid (AA) could have detrimental effect to the environment due to its high value of chemical oxygen demand. Reactive distillation column (RDC) could be a promising treatment method to recover AA from the waste water. In the present work, activity and kine...

Reactive distillation column (RDC) could be a promising treatment method to recover AA from the waste water. In the present work, activity and kinetic studies of the esterification of AA and 2-ethyl hexanol (2EH) were carried out in a batch system to examine the practicability of this method.
