Rates of reaction of 2,4,6-Tri-t-butylphenol with nitrogen dioxide (1000 ppm) have been determined in a batch reactor. The kinetics of reaction has qualitative distinctions according to the initial phenol concentration in the hexadecane solution. The phenol decay proceeds with fixed rate in time depending on the flow rate of NO2 at [PhOH]0 = 4.0·10 At[PhOH]0 = 6.0·10-5M the kinetics is controlled by the first order law. The rate constant of the phenolic hydrogen atom abstraction by NO2 is k1 = 5.9·-103 exp (-10kJ/RT), M-1s-1. At 22°C the rate constant of NO2 and phenoxy radical recombination is 76.5 M-1s-1. The formation of the reaction products has been studied by UV spectroscopy. The mechanism of nitration and side reactions in a batch reactor has been discussed. |
