Properties of Urea.—Urea is a white, crystalline solid, with a faint, salty taste. It separates from aqueous solutions in long prismatic crystals that melt at 132-6° C. (corr.), and above this temperature dissociate into cyanic acid and ammonia. Urea is very soluble in water, glycerol, and methyl alcohol, and to a less extent in hot ethyl alcohol and in acetone. It is insoluble in ether, chloroform, and benzene.
