KINETICS OF WET AIR OXIDATION OF DIETHANOLAMINE AND MORPHOLINE

The kinetics of Wet Air Oxidation of morpholine and diethanolamine (DE A) in aqueous solutions, were studied. The rates of destruction were m easured with respect to reduction in substrate concentration and with respect to reduction in Chemical Oxygen Demand (COD). The studies were performed in the temperature range of 160-240 degrees C and oxygen pa rtial pressure was in the range of 0.34-1.36 MPa. The order with respe ct to COD and substrate concentration (morpholine and diethanolamine) was found to be one. Order with respect to oxygen concentration ranged from 0.3 to 0.9. The energy of activation was found to be in the rang e of 18.5-27.24 kcal/gmol. Monoethanolamine was found to be one of the intermediates formed during oxidation of morpholine and DEA. The mixt ures of diethanolamine and morpholine were found to oxidize faster tha n that expected from the individual rate of oxidation.
