The catalysed thermal decomposition of organic acids. Part I. The catalysed decomposition of cyclohexanecarboxylic acid by hydrogen bromide

Abstract

Hydrogen bromide catalyses the thermal decomposition of cyclohexanecarboxylic acid into essentially cyclohexene, carbon monoxide, and water in the temperature range 642–703 K in a seasoned Pyrex reaction vessel. The first-order rate constants are proportional to the hydrogen bromide concentration. The reaction is homogeneous and predominantly molecular. The Arrhenius equation is k₂/cm³ mol^–1 s^–1= 10^13·562 exp (–34,480/RT).
