Morpholine are mainly used to manufacture rubber accelerant (such as NOBS, OTOS and MDS), sulfuration agent (like DT-DM), cleanser, descaling agent, antitrust, anti-scorching agent, antiseptic, surfactant, textile printing & dyeing agent, optical bleaching agent, chemical plating bath, antioxidant, hydrolyzing agent, initiator, developer, fruit preserving agent, deodorizer, brightener, and organic solvents. It is widely used in many industries such as medicine, pesticide, animal medicine, petroleum and extraction of coke aromatic hydrocarbon.

In foreign countries, a great deal of morpholine is used for antitrust, descaling and metal cleaning, especially for antitrust and anticorrosive in high-temperature conditions.

In boiler maintenance fields, the amount of morpholine is also used as a descaling agent. Owing to its unique chemical characters, morpholine has become one of the most important fine petroleum chemical products.
