Özet:

 

The kinetics of oxidation of n--Propanolamine (n-PA) by  dihydroxy diperiodato-nickelate(IV) (DPN) in alkaline medium was  studied with spectrophotometry in a temperature range of 293.2-308.2  K. The reaction was found to be pseudo first-order with respect to DPN  and fractional order to n-PA. The rate conatant kobs, rose with an  increase in the concentration of OH- and a decrease in the  concentration of IO4-.  Added salts did not affect the rate and  no free radical was detected.  From the evaluation of linear data, a  reaction mechanism is proposed which involves a pre-equilibrium of an  adduct formation between n-PA and dihydroxymonoperiodatonickelate(IV)  (MPN), and the activation parameters of the rate-determining step have  been calculated.
