Abstract Two analytical procedures based on the magnitude of the heat of dilution and direct injection enthalpimetry have been developed for determination of water in ethanol and acetone. The results obtained by means of the heat of dilution were compared with the values given by pycnometry, and gave a relative difference in the range 0.2-3\%. The precision depends on the slope of the calibration curve, which varies with the procedure and the concentration of the sample.
