Summary

  1. 1.

    The formation of Ni-MgO catalysts proceed through the stage of anhydrous mixed oxalates. Only two crystallines phases are found in the active catalyst: β -Ni, and MgO.

     
  2. 2.

    The anhydrous simple and mixed oxalates of nickel and magnesium have been obtained and identified by X-ray means for the first time.
