Solubility

Because of its hydroxyl groups, glycerine has solubility characteristics similar to those of water and the simple aliphatic alcohols. It is completely miscible with water, methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, n-butyl alcohol, isobutyl alcohol, sec.-butyl alcohol, tertiary amyl alcohol, ethylene glycol, propylene glycol, trimethylene glycol and phenol.

Glycerine has limited solubility in dioxane and ethyl ether. It is practically insoluble, however, in higher alcohols, fatty oils, hydrocarbons, and chlorinated solvents such as chlorhexane, chlorbenzene and chloroform. It is completely miscible with ethylene glycol monoethyl ether but is miscible with only a limited amount of ethylene glycol monobutyl ether.

Because of the importance of glycerine as a solvent in pharmaceutical preparations and flavor extracts, considerable work has been done on the solubility of a number of substances in glycerine.
