Abstract
The gas-phase spontaneous and acetic acid-catalysed additions of water to keten have been studied kinetically in the range 224–324 °C. The uncatalysed addition is heterogeneous, with an apparent activation energy of 10·7 kJ mol–1, and is inhibited by acetic acid. The catalysed reaction is homogeneous and first order in all three reactants, k= 104·34 exp (–20,500/RT) l2 mol–2 s–1. The activation parameters agree with those calculated from the back reaction and equilibrium constant.Keywords
