Morpholine, also named Tetrahydro-1,4-oxazine / 1-Oxa-4-azacyclohexane, CAS 110-91-8, is a typical heterocyclic organic compound containing both amine and ether functional groups. Our plant adopts continuous catalytic synthesis and multi-stage rectification technology to produce industrial grade morpholine with purity ≥99.5%.

The unique molecular structure endows morpholine with moderate alkalinity and excellent solvent capacity. It can react with acids, alkylating agents and acylating agents to generate various morpholine derivatives, making it an irreplaceable building block in fine chemical manufacturing. Compared with low-purity morpholine in the market, our product strictly controls moisture, diethylene glycol and other residual impurities, ensuring stable reaction conversion rate in downstream synthesis. It serves as core raw material for rubber additives, water treatment chemicals, medical intermediates, agricultural fungicides and textile auxiliaries, supporting long-term bulk supply for global manufacturers.

Morpholine Application

1. Rubber Industry (Largest Consumption Field)

Key intermediate for delayed-action vulcanization accelerators such as NOBS, DTDM, OTOS. Effectively prevent premature vulcanization during rubber mixing, enhance heat resistance and anti-aging performance of tires, hoses and rubber parts.

2. Water Treatment Industry

Volatile neutralizing amine & corrosion inhibitor for steam boiler and condensate pipeline systems. Forms protective film on metal surface to suppress carbon dioxide corrosion, widely used in power plants and chemical heating systems.

3. Pharmaceutical & Pesticide Synthesis

*Pharma: Intermediate for antibiotics, local anesthetics, antidepressant medicines;

*Agrochemical: Raw material for morpholine-type fungicides to control powdery mildew and downy mildew on fruits and vegetables.

4. Textile & Dyeing Industry

Synthetic raw material for optical brighteners; pH regulator and auxiliary solvent in printing and dyeing formulations.

5. Other Industrial Applications

Organic solvent for resins, wax and shellac; fruit fresh-keeping coating auxiliary; surfactant intermediate; laboratory analytical reagent.

FAQ

1. What is the main application of morpholine?

It is most widely used for producing rubber vulcanization accelerators, followed by boiler water treatment corrosion inhibitors, pharmaceutical and pesticide intermediates.

2. Is morpholine dangerous for export transportation?

Yes, UN2054 Class 8 corrosive + Class 3 flammable liquid. We supply complete dangerous goods certification and cooperate with qualified hazardous logistics providers.

3. Can morpholine be mixed directly with strong acid?

Not recommended. It will react violently with strong acid and release heat, need slow addition under stirring.

4. What is your MOQ?

Sample order 1–5L; bulk minimum order is 200L iron drum.

5. What documents can you offer for customs clearance?

COA, MSDS, UN dangerous package certificate, commodity inspection report, CO and full customs declaration materials.
