        Specific illustrations indicate their extreme usefulness in the organic field.  Their high degree of selectivity and their resistance to the ordinary catalyst poisons are outstanding characteristics.  The results obtained in the studies of MeOH and higher alcohols are helpful in throwing light on the catalytic and general physical properties of this class of oxides.  It was found that a definite relation exists between the synthesis of the alcohol from CO and H₂ at high pressure and its decomposition over the same catalyst combinations at atmospheric pressure.  So close was the agreement between the two sets of observations that the simple and inexpensive decomposition method could be used for evaluating the usefulness of catalysts for the high pressure synthesis.  It was also found that in the decomposition of MeOH, any mixture of 2 oxides (ZnO-CuO, ZnO-Cr₂O₃) had a synergistic effect, the addition of 3 mol. % ZnO to CuO increasing the rate approximately 3 times.
