%X The thermal decomposition of 2-methylpropan-2-ol has been investigated from 503 to 612°C, over initial pressures ranging from 40 to 275 mm and in the presence of toluene from 520 to 602°C. The decomposition is homogeneous and first order with respect to the initial concentrations of alcohol giving the Arrhenius equation (R = 8.31 J mol-1 K-1)                              K=1012.7exp(-249,800/RT) s-1  for the initial rate. The decomposition of this alcohol is inhibited by the reaction products, mainly 2-methylpropene, and by the addition of toluene. There are contributions from the unimolecular elimination of water (k = 1013.6exp(-268,000/RT)s-1) and from a flee radical process (k = 1011.0 x exp(-227,000/RT) s-1). A free radical mechanism, which explains the minor products of the reaction and the varying results of other workers, is proposed.
