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.
基于稀释热大小和直接进样量热法开发了两种分析方法，用于测定乙醇和丙酮中的水分。通过稀释热法获得的结果与比重瓶法给出的值进行了比较，相对差异在0.2%-3%范围内。精密度取决于校准曲线的斜率，该斜率随方法和样品浓度的不同而变化。
