Following promotors were used in conjunction with the 4ZnO.Cr₂O₃ catalyst: W, V, Th, Ce, La, Ta, and Zr. The experiments were carried out with a decreasing pressure, each being carried out for 60 min. with 500 cc. of the catalyst. The highest MeOH yields were obtained with the promotors (1%) ThO₂, ZrO₂ and TaO₂. The results are tabulated and plotted.
