Equilibrium of the reaction CH₃OH=HCHO+H₂(I) and HCHO=CO+H₂(II) were determined by a static method with Cu-pumice catalyst. For (I) the value found for K_p at 155° was 0.37 and at 205°, 0.65; these values differ widely from those calculated by a Nernst-type equation. For (II) the values of K_p from 155° to 340° (ranging from 0.032-2.20) were represented fairly well by the equation: log₁₀K_p=-(11,800/4.571T) +1.75 log₁₀T-0.001T+0.3.
