Description

A colorless, hygroscopic liquid with a characteristic amine odor. Morpholine is miscible with water, but it evolves heat in the process forming a basic solution that can saponify dried oil films and aid in their removal. Morpholine is also used to dissolve resins, waxes, casein, shellac, and dyes. It can also act as a surfactant and emulsifier. Morpholine has been used as a corrosion inhibitor in fire sprinkler and HVAC systems. It has also been used as a vapor phase neutralizing/alkalizing agent, but it is not recommended because of its toxicity, disagreeable odor, and poor ability to provide residual alkalinity. Some materials treated with morpholine, such as leather and pyroxylin coated book covers, have exhibited color changes (Book and Paper Catalog).
