摘要：

The enthalpies of dilution of NaCl, Me4NBr, and n-Bu4NBr were measured in water at 25 degrees C with a new flow microcalorimeter, The data were analyzed with a polynomial equation, and the derived relative apparent molal enthalpies phi(L) are in good agreement with literature values. Provided care is taken that mixing is complete, flow calorimeters are as reliable and much less time-consuming than cell-type instruments for enthalpies of dilution measurements.
