Morpholine CAS 110-91-8 8 Chemical Intermediate & Corrosion Inhibitor & Water Treatment & Rubber

What is Morpholine? 

Morpholine is a colorless, oily heterocyclic organic compound with a mild ammonia-like odor. Its molecular formula is C₄H₉NO, and its IUPAC name is 1,4-Oxazinane / Tetrahydro-2H-1,4-oxazine.

It features both amine and ether functional groups in its molecular structure, giving it dual properties of alkalinity and solubility. It is miscible with water and most organic solvents, and is widely applied as a key industrial chemical raw material.

Application of Morpholine

1. Corrosion Inhibitor for Water & Steam Systems

This is one of the most mainstream uses of morpholine. It works as an effective neutralizing amine to prevent metal corrosion.Protects industrial boilers, steam pipelines, heat exchangers and cooling water circulation systems.

Neutralizes acidic substances in water, stabilizes pH value, and reduces rust and oxidation of metal facilities.

Widely used in power stations, oil refineries, chemical plants and central heating systems.

2. Key Intermediate for Rubber Chemicals

Diethyleneimide oxide is an indispensable raw material in the rubber industry.

Mainly used to produce rubber vulcanization accelerators, vulcanizing agents and anti-aging additives.

Enhances the processing performance, elasticity and service life of natural rubber and synthetic rubber products.

Also serves as an auxiliary agent in the production of polyurethane materials.

3. Intermediate for  Agrochemicals

High-purity morpholine is a core material for fine chemical synthesis.

Applied to manufacture intermediates, Used for producing pesticides, herbicides and fungicides in agrochemical production.

Strict quality grade is required for agrochemical manufacturing scenarios.

4. Solvent for Coatings, Inks & Resins

Owing to excellent solubility, morpholine is a common polar organic solvent.

Dissolves resins, waxes, dyes and high-molecular polymers efficiently.

Added into paints, industrial coatings and printing inks to improve fluidity and film-forming effect.

Applied in resin processing to optimize product stability.

5. Textile & Daily Chemical Industry
