Kinetic Study Of Ethyl Aceto Acetate And Malonic Ester By Isoquinolinium Bromochromate In Acetic Acid Medium

The kinetic study of ethyl aceto acetate (EAA) and Malonic ester (ME) by Isoquinolinium bromochromate (IQBC) in aqueous acetic acid medium is presented. The reaction obeys a fractional-order with respect to substrates and first-order with respect to oxidant IQBC. The added H+ catalysed the reaction rate. The rise in percentage of acetic acid increased the rate of reaction. The redox reaction did not initiate polymerization with acrolonitrile and free-radical mechanism is ruled out. Based on the observations and determined activation parameters for the reactions a plausible mechanism and rate law were proposed.
