PATENTS
ZnO, CuO, MnO, or Cr2O3 or hydroxides, alone or mixed after adding an alkali complex salt of the single or mixed metals and then heating, forms a long-lasting active catalyst for making iso-BuOH from H2 and CO. For example, H2 and CO (2:1) passed at 40° and 150 atm. over Zn(OH)2 and Cu(OH)2 [precipitated together from Zn(NO3)2 2 and Cu(NO3)2 1 molecule with NaOH, dried at 400°, and powdered], heated 100°-400° with 1 molecule K3[Cr(C2O4)3]·3 H2O gave 30% iso-BuOH and only 15% higher alcohols.
