Molar excess enthalpies of water-alcohol systems have been analyzed to give equilibrium constants and enthalpies of the reactions 2ROH + D/sub 2/O = 2ROD + H/sub 2/O (R = CH/sub 3/, C/sub 2/H/sub 5/, n-C/sub 3/H/sub 7/). The equilibrium constants are significantly greater than the ''random'' value. Molar excess enthalpies of alcohol-alcohol systems have been analyzed to give enthalpies of reactions ROH + R'OD = ROD + R'OH. The enthalpies of water-alcohol and alcohol-alcohol exchange reactions form a self-consistent set and are in good agreement with values from earlier studies. Molar excess enthalpies at 298.15 K are reported for n-C/sub 3/H/sub 7/OH and n-C/sub 3/H/sub 7/OD with H/sub 2/O, D/sub 2/O, CH/sub 3/OH, CH/sub 3/OD, C/sub 2/H/sub 5/OH, and C/sub 2/H/sub 5/OD.
