Mutual binary solubilites have been measured for partially miscible water-organic pairs at temperatures of 0-90-degrees-C. Experimental data are given for 37 ketones, 16 ethers, 14 esters, 10 chloroparaffins, and 4 nitroparaffins. Data are also given for 18 ternary systems, including several gasoline systems of environmental interest. In essentially all cases, the solubility of water in the organic layer increases with temperature. The solubility of the organic species in the water layer usually decreases with temperature, often going through a minimum at about 60-degrees-C and then increasing at higher temperatures. Ternary systems involving water-gasoline-alcohols show that methanol distributes almost entirely in the aqueous layer, but the distribution shifts more to the organic layer as the molecular weight of the alcohol increases. Lower alcohols increase the solubility of aromatics in the aqueous layer; for higher alcohols such as pentanol and hexanol, aromatic solubility in the aqueous layer first increases with alcohol content, goes through a maximum, and then decreases.
