✦ Synopsis

boiling data were obtained for 7 concentrations of isopropanol in water and 9 concentrations of acetone in water, as well as for 3 pure components. The heating element was a nickelaluminium alloy wire of 0.03 15 cm in dia. These experimental results were correlated with the equation [g][er = '[ l+ I,," -Px;(a,D)0.5r" This equation also correlated the experimental data of Stemling and Tichacek [ 121 for several mixtures of water with glycerol and water with glycol.

Our experimental results and those of Ref.

[ 121 indicate that the "liquid-surface combination factor" is determined mainly by the nature and structure of the heat transfer surface. The contribution of the liquid to this factor is very small, within the accountable experimental error. The value of the constant E in the correlating equation is mainly a function of the surface.
