Abstract
The kinetics of synthesizing methyl nitrite via the gas–liquid reaction of N 2O 3 with methanol was studied in a double-stirred cell reactor with a plane, horizontal gas–liquid interface, in the temperature range of 278–298 K. Since N 2O 3 is stable only below 0 °C, a mixture of NO and NO 2 with the ratio of 1:1 behaves chemically like N 2O 3 and replaces it. The Henry's constants and diffusion coefficients of NO and NO 2 in the liquid phase were estimated, and it was found that the generating rate of methyl nitrite was only affected by the partial pressure of NO in the gas phase. The reaction between N 2O 3 and methanol was fast pseudo-first order, and a kinetic equation was obtained as follows: R MN = 2 P NO H NO C 0 D NO × 6.546 × 10 9 exp − 57 , 416 R T × C 0
