  1. 1.

    The configurational isomerization of stereoisomeric 1,4-dimethoxycyclohexanes on Pt/C proceeds only in the presence of free hydrogen.

  2. 2.

    A phenomenon of development of the catalyst (Pt/C) in the configurational isomerization of the indicated diethers under the action of dimethoxycyclohexane and anisole was detected.

  3. 3.

    The influence of the temperature of volume velocity on the configurational isomerization and degree of decomposition (hydrogenolysis and dehydrogenation) was studied. The activation energy of the transition of cis-1,4-dimethoxycyclohexane to the trans-form was determined.

  4. 4.

    Considerations were expressed on the mechanism of the reaction studied.
