      Catalyst prepared by precipitating the nitrates with NaOH to give an atomic ratio of 3 Cu : 1 Cr in contact with a 2 : 1=H₂ : CO mixture at 180 atm. yielded MeOH and Me₂O in the following molecular % ratios:  265°, 7:4; 285°, 14:6; 305°, 24:22; 340°, 17:20; 355°, 11.5:13.5.  The region of maximum conversion was 315°-320°, and conversions were on the order of 30 mol. %, that to Me₂O being the larger.
