Morpholine
It is used as a corrosion inhibitor in boilers and other water circulation systems. The vapor pressure of morpholine is similar to that of water and can be dissolved in water at any ratio.
Morpholine Aqueous Solution – Corrosion Inhibitor for Boiler & Water Circulation Systems
Morpholine Aqueous Solution is a weakly alkaline chemical widely used as a corrosion inhibitor and pH-conditioning agent in boilers, steam systems, and industrial water circulation systems. It effectively neutralizes carbonic acid formed in aqueous systems, helping reduce the risk of corrosion in pipelines, condensate lines, heat exchangers, and associated equipment.
Morpholine has a vapor pressure relatively close to that of water and is highly miscible with water, allowing it to distribute effectively throughout water circulation and steam-condensate systems. This characteristic helps maintain a stable and controlled pH level, particularly in condensate systems where carbon dioxide can contribute to acidic conditions.
Morpholine is often used together with other neutralizing amines or water-treatment chemicals to address specific corrosion-control requirements and provide comprehensive protection for boiler and circulating-water systems.
Key applications include:
-
Boiler water treatment
-
Steam and condensate systems
-
Industrial water circulation systems
-
Corrosion control in pipelines
-
Heat exchangers and cooling systems
-
pH adjustment and conditioning
-
Condensate corrosion protection
Key benefits:
-
Helps neutralize carbonic acid

Rust
The morpholine aqueous solution is weakly alkaline and can effectively neutralize the carbonic acid in the acidic aqueous solution. It is used as a corrosion inhibitor in boilers and other water circulation systems. The vapor pressure of morpholine is similar to that of water and can be dissolved in water at any ratio. It can maintain a constant pH value in the water circulation system and is therefore often used in conjunction with other amine compounds to solve special corrosion problems in the water circulation system.
Metalworking fluid additives
Due to the characteristics of low toxicity, weak alkalinity and miscibility with water, Mimi can be added to water-based metal working fluids to prevent metal rust, corrosion, sterilization and adjust the pH value of metal working fluids; in combination with water Adding a certain amount of morpholine or morpholine derivatives into the contacting lubricating oil as a corrosion inhibitor can effectively prevent corrosion of operating equipment parts; in petroleum storage tanks, pipelines and distillation equipment, adding petroleum carbonate morpholine can effectively to prevent corrosion
other
Morpholine can also be used to synthesize fluorescent whitening agents, aromatic hydrocarbon extractants, initiators and surfactants, textile auxiliaries, antioxidants, cleaners and polishes, etc. Morpholine aqueous solution is alkaline and can be used to remove hydrogen sulfide, carbon dioxide or hydrogen cyanide from acidic gases. As the research on morpholine continues to deepen, new uses of morpholine are constantly being developed, and the consumer market continues to expand, setting off a new upsurge in domestic research on morpholine and its derivatives.
