OH-initiated degradation of methyl 2-chloroacetoacetate and ethyl 2-chloroacetoacetate: Kinetics, products and mechanisms at 298 K and atmospheric pressure

Autor: Mariano A. Teruel, G C Vianni Straccia, Cynthia B. Rivela, Pedro L. Lugo, María B. Blanco, Peter Wiesen

Publikováno v: Chemosphere. 274

Rate coefficients for the gas-phase reactions of OH radicals with CH3C(O)CHClC(O)OCH3 (k1) and CH3C(O)CHClC(O)OCH2CH3 (k2) were measured using the relative technique with different reference compounds. The experiments were performed at (298 ± 2) K a
