An isoperibol flow calorimeter has been designed and assembled. The calorimeter is for the collection of calorimetric data at temperatures up to 400/sup 0/C. The isoperibol calorimetric data for the following systems in decane as solvent: Quinoline - Aniline; Quinoline - m-Cresol; and m-Cresol - Aniline have been fit by least squares analysis techniques to produce the reactions and thermodynamic values given in Table I for this ternary system. Isoperibol titration data have been obtained at 25/sup 0/C for the interactions occurring in the following systems in decane solvent: m-Cresol - Naphthalene; m-Cresol - tetralin; m-Cresol - 8-Hydroxyquinoline; m-Cresol - ..cap alpha..-Fe/sub 2/O/sub 3/; m-Cresol - ..gamma..-Al/sub 2/O/sub 3/; and m-Cresol - Activated Charcoal. Isothermal flow calorimetric data have been obtained at 100 and 200/sup 0/C for the heat of mixing curves of the following binary systems: Quinoline - Aniline; Quinoline - m-Cresol; m-Cresol - Aniline; and m-Cresol - Furan and at 25/sup 0/C for the systems: m-Cresol - Aniline; and Quinoline - m-Cresol. A computer program has been developed for the analysis of the heat of mixing data to determine the ..delta..G, ..delta..H and ..delta..S values for the formation of molecular complexes in the binary liquid pairs.
