Anhydrous ethanol with soluble salt

The solubility of the sodium salt of (meta-sulfonatophenyl)diphenylphos-phine, TPPMS in water is approximately 12 g/L at room temperature.5 It dissolves slightly in cold ethanol, but is soluble at elevated temperatures. It is virtually insoluble in acetone and aliphatic, aromatic, or chlorinated hydrocarbons, but is soluble at room temperature in tetrahydrofuran. The compound crystallizes with two waters of crystallizations however, the anhydrous form can also be obtained.3 Dry TPPMS is stable to air but is oxidized rapidly when wet, especially in basic aqueous solutions. It is a highly surfactant compound and forms aggregates and micelles in neutral aqueous... 

The Hammond Co. supplies an indicating form which turns from blue to red when exhausted. It is prepared by impregnating the surface of the calcium sulfate granules with 3.5-5% of anhydrous cobalt chloride. The blue cobalt salt is indifferent to aprotic solvents insoluble in water (benzene) or partially soluble in water (diethyl ether), but is leached off by water-miscible solvents, both protonic (ethanol, acetic acid) tmd aprotic (dimethylformamide, dimethyl sulfoxide, triglyme). 

Ammonium azide is a white crystalline salt, with the following solubilities per 100 ml. of solvent, at 20° water 20 g. methanol 3.3 g. ethanol 1.06 g. ether 0.006 g. benzene 0.003 g. It crystallizes from aqueous solutions in anhydrous form, has a relatively high vapor tension, and sublimes at 133° without melting. It is one of the more stable azides but, when properly initiated, detonates with high velocity. It usually detonates with extreme violence when heated in a sealed tube but not in the open air. 

A colourless crystalline compound, CHaCOONa, which is known as the anhydrous salt (r.d. 1.52 m.p. 324°C) or the trihydrate (r.d. 1.45 loses water at 58°C). Both forms are soluble in water and in ethoxyethane, and slightly soluble in ethanol. The compound maybe prepared by the reaction of ethanoic acid (acetic acid) with sodium carbonate or with sodium hydroxide. Because it is a salt of a strong base... 

Barium thiocyanate is a white solid that is very soluble in water but has a very steep temperature-solubility gradient. This solid is also soluble in acetone, methanol, ethanol, methylamine and ethylamine, moderately soluble in isopropylamine and dimethylamine, but insoluble in trimethylamine. The anhydrous salt is very hygroscopic. Crystallization from water yields the 3-hydrate as well-formed, needle-shaped crystals. Double salts are formed with the thiocyanates of the alkali and other alkaline earth metals. ...
