Summary Tristearin, triolein, 1,2‐diaceto‐3‐olein, an acetoolein product, and 1,2‐dibutyro‐3‐olein were prepared. Also a commercial, refined, and bleached cottonseed oil was hydrogenated to obtain products having iodine values of 29.3 and 1.1. Solubility measurements were made for the mixtures tristearin‐triolein, tristearin‐1,2‐diaceto‐3‐olein, tristearin‐1,2‐dibutyro‐3‐olein, and for hydrogenated cottonseed oils in the aceto‐olein product and cottonseed oil. In mixtures containing from 0.18% to approximately 30% of tristearin the solubility on a weight basis was unaffected by the nature of the oil. On a mole fraction basis the tristearin was most soluble in the triolein and least soluble in the 1,2‐diaceto‐3‐olein. Hydrogenated cottonseed oil appeared to be about equally soluble, on a weight basis, in the aceto‐olein product and cottonseed oil.
