Abstract
Kinetics and Mechanism of N2H4-KBrO3 reaction in the presence of allyl alcohol have been studied. The pseudo-first order rate constant for gas evolution was found to be 10-4∼10-2 sec-1 at 25.0 ± 0.1℃, increasing with concentration of hydrogen ion. When concentrations of sulfuric acid and allyl alcohol are both sufficiently high, the following overall reaction explains experimental results reasonably well: N2H4 + BrO3- + H+ → N2 + HOBr + 2H2O, CH2 = CHCH2OH + HOBr → CH2OHCHBrCH2OH. More complicated reaction mechanisms at lower acidity conditions have been contemplated.
