57 grams of oleate. These solubilities diminish, as the temperature or concentration of alcohol decreases. Peanut oil contains glycerides of oleic, linolic, palmitic, arachidic and lignoceric acids. It was assumed, in the following experiments, that the principle of the greater solubility of the magnesium soap of oleic acid in 90 per cent alcohol would apply to that of linolic acid and that the arachidate would have the same low solubility as stearate and lignocerate. This was afterward found t...o be true. 1. PREPARATION OF REAGENTS (1) Alcoholic potassium hydroxide solution: Fifty grams of po- tassium hydroxide ("purified by alcohol") were dissolved in one liter of alcohol and filtered to remove impurities. This alcohol was the purified product obtained by distillation of 95 per cent alcohol that had been in contact with potassium hydroxide and silver oxide for one week. Fifty c. C. Of this solution are more than sufficient for saponifying 10 grams of peanut, castor, corn, cottonseed, linseed, sesame, soya bean or tung oil.
