Studies on High Molecular Weight Aliphatic Amines and their Salts. II. Solubilities of Primary Aliphatic Amine Hydrochlorides and Acetates in Ethanol and Benzene

The Solubilities of the Normal Saturated Fatty Acids

“…The solubilities of the fatty acids in the organic solvents were determined in sealed tubes by the method and with the apparatus previously described (8,12,13). The depression of the freezing points of benzene and of glacial acetic acid by the addition of known amounts of fatty acids was determined using 25-g. portions of solvent The reproducibility of the results presented are shown by the following examples : for caprylic acid at 20.0°the experimental results gave a value of 0.068 ± 0.002 g. acid per 100 g. water, an average of 7 separate determinations; for lauric acid at 45.0°, 0.0075 ± 0.0005 g. for 6 determinations; and for heptadecylic acid at 30.0°, 0.00055 ± 0.00003 g. for 8 determinations.…”

Solubilities of High Molecular Weight Symmetrical Normal Aliphatic Ketones

“…The solubilities of the ketones in these solvents were determined in sealed tubes by the method and with the apparatus previously described (10,21,22,23). Temperatures were measured with an accurately calibrated thermometer which was graduated in 0.1°intervals.…”

Solubilities of Some Normal Aliphatic Amides, Anilides, and N,n-Diphenylamides

“…The solubilities of the amides and their derivatives were determined in sealed tubes by the method and with the apparatus previously described (38,39). The solvents which were employed were those used in previous solubility studies (40).…”
