Conclusions

  1. 1.

    The catalytic dehydration of a 2-alkanol on metal oxides proceeds in two directions by different mechanisms.

     
  2. 2.

    In the presence of catalysts of a basic nature, namely oxides of the metals of Groups II and III of the periodic system of elements, the dehydration of a secondary alcohol apparently goes by the carbanion mechanism toward the formation of theα-olefin.

     
  3. 3.

    On catalysts of an acid nature, namely the oxides of the metals of Groups IV, V, and VI, the dehydration of the carbinol proceeds by the carbonium-ion mechanism with the predominant formation of theβ-olefin.
