EXCESS-ENTHALPIES FOR THE SYSTEMS 1,3-BUTANEDIOL PLUS CYCLOHEXANOL PLUS DECANE AND 1,2-PROPANEDIOL PLUS 1,3-BUTANEDIOL PLUS CYCLOHEXANOL AND FOR CONSTITUENT BINARIES AT 318.15 K

Excess enthalpies (H-E) were determined for two ternary systems, 1,3-b utanediol + cyclohexanol + decane and 1,2-propanediol + 1,3-butanediol + cyclohexanol, and for their five constituent binaries at 318.15 K w ith a Calvet-type microcalorimeter. The ternary liquid-liquid coexiste nce curve for the first ternary system was measured at 318.15 K by the titration method. From the experimental results for binary systems, p arameters of the Redlich-Kister equation were obtained and used to pre dict the ternary H-E results.
