Unimolecular Decomposition Of Formic And Acetic Acids: A Shock Tube/Laser Absorption Study, A. Elwardany, E. F. Nasir, Et. Es-Sebbar, A. Farooq

Dr. Et-touhami Es-sebbar

The thermal decomposition of formic acid (HCOOH) and acetic acid (CH3COOH), two carboxylic acids which play an important role in oxygenate combustion chemistry, were investigated behind reflected shock waves using laser absorption. The rate constants of the primary decomposition pathways of these acids: The thermal decomposition of formic acid (HCOOH) and acetic acid (CH3COOH), two carboxylic acids which play an important role in oxygenate combustion chemistry, were investigated behind reflected shock waves using laser absorption. The rate constants of the primary decomposition pathways of these acids: HCOOH→CO+H2O (R1) HCOOH→CO2+H2 (R2) CH3COOH→CH4+CO2 (R3) CH3COOH→CH2CO+H2O (R4) were measured using simultaneous infrared laser …
