Abstract: With deuterium present in the formyl group, the equilibrium constant for transfer of N-methylformamide from chloroform to D20 at 25" C was enhanced by a factor of 3.1 & 0.15%, as estimated independently by proton magnetic resonance and by double-labeling experiments in which I4C and, H were incorporated alternatively into the methyl group. The distribution coefficient of acetaldehyde-1-d between D20 and the vapor phase, on the ...
