Abstract

The kinetics of the gas phase pyrolysis of methyl 3-bromopropionate, under maximum catalysis of HBr, were found to be of order 1.0. The reaction appears to undergo a molecular elimination of HBr, which follows first-order kinetics. The products are methyl acrylate and HBr. The pyrolysis, in s static system and seasoned vessel, was examined over the temperature range of 330.5–378.5°C and pressure range of 64–145 Torr. The rate coefficients, under maximum catalysis, are given by the Arrhenius equation log k1(s−1)=(11.19±0.64)−(171.6±7.7) kJ/mol/2.303 RT. The mechanism of the catalyzed pyrolysis of the bromoester appears to proceed through a six-membered cyclic transition state.

Abstract

Кинетика газофазного пиролиза метилового 3-бромпропионата при максимальном катализе HBr-ом имеет порядок, равиый 1,0. При реакции происходит отщепление молекулярного HBr по кинетике первого порядка. Продуктами являются метилакрилат и HBr. Пиролиз в статической системе и высушенном сосуде изучали в интервале температур 330,55–378, 5°C и при давлении 64–145 торр. Константа скорости при максимальном катализе описывается следующим аррениусовским уравнением: log k1 (cek−1)=(11,9±0,64)−(171,6±7,7) кДж/моль/2,303 RT. Механизм
