Morpholine appears as a colorless liquid with a fishlike odor. Flash point 100°F. Corrosive to tissue. Less dense than water and soluble in water. Vapors heavier than air. Used to make other chemicals, as a corrosion inhibitor, and in detergents.

 

Morpholine is an organic chemical compound having the chemical formula O(CH2CH2)2NH. This heterocycle features both amine and ether functional groups. Because of the amine, morpholine is a base; its conjugate acid is called morpholinium. For example, treating morpholine with hydrochloric acid makes the salt morpholinium chloride. The naming of morpholine is attributed to Ludwig Knorr, who incorrectly believed it to be part of the structure of morphine.
