Abstract
The gas-phase decomposition
of 2,3-dimethylbutan-2-ol into 2,3-dimethylbut-1-ene, 2,3-dimethylbut-2-ene,
and water, catalysed by hydrogen bromide at 303-400�, is described. The rate is
first-order in each reactant and the Arrhenius
equation
k2 = 1011.88 exp(-26490/RT) sec-l ml
mole-1
is followed. The olefins
appear to be in their equilibrium proportions. The effects of substitutions in
the alcohol at Cα and Cβ on the rate are discussed.
