Product Description
Features
Our N-Methylethanolamine is manufactured to exacting quality standards, guaranteeing high purity, low water content, and consistent chemical composition. With a molecular formula of C3H9NO, N-MEA's dual functional groups enable high reactivity and versatility in a variety of industrial processes, from surfactant synthesis to pharmaceutical intermediate production.
Advantages
Lower regeneration energy than MEA: MMEA requires less steam for thermal regeneration in gas sweetening units → reduces operating costs by an estimated 15–20%.
Reduced corrosion tendency: Compared to MEA and DEA, MMEA exhibits milder corrosivity to carbon steel equipment → extends equipment lifespan and lowers maintenance frequency.
Higher selectivity for H₂S over CO₂: In selective treating applications, MMEA absorbs H₂S preferentially, allowing partial CO₂ slip to meet pipeline specifications.
Excellent thermal stability: Less susceptible to degradation products (heat stable salts) than primary amines → longer amine solution life and reduced reclaimer waste.
Custom packaging options: 180kg drums, 1000L IBC totes, or bulk ISO tank containers for large-volume orders.
Benefits
Utilizing our N-Methylethanolamine enables manufacturers to achieve higher yield, better product consistency, and improved performance in surfactants, coatings, and polymer systems. Its chemical stability and predictable reactivity reduce operational risks, lower production costs, and facilitate regulatory compliance.
Evidence
Quality analysis confirms a purity of ≥99%, low water content, and minimal residual impurities. ISO-compliant production and stringent quality assurance ensure reliability for demanding industrial applications. Many clients worldwide rely on our N-MEA for its consistent performance in pharmaceuticals, specialty chemicals, and industrial formulations.

FAQ
Q1: Can MMEA be blended with other amines?
A: Yes. MMEA is commonly blended with MDEA (methyldiethanolamine) or formulated in proprietary amine mixtures to balance selectivity, capacity, and regeneration energy. We can provide guidance on compatible blends for your specific gas composition.
Q2: What safety precautions are required when handling MMEA?
A: MMEA is corrosive to eyes and skin and can cause respiratory irritation. Use chemical-resistant gloves, safety goggles, and adequate ventilation. In case of skin contact, wash immediately with plenty of water. We provide an MSDS with every shipment detailing safe handling procedures.
Q3: What packaging options do you offer for MMEA?
A: We offer 180kg net weight steel drums, 1000L IBC totes (approximately 935 kg net), and bulk tank containers (ISO tanks) for orders exceeding 18 tons. All packaging complies with hazardous material transport regulations (UN 2735, Class 8).
Q4: What is the shelf life of MMEA?
A: 24 months from production date when stored in a cool, dry, well-ventilated area in original sealed containers. Keep away from acids, oxidizers, and direct sunlight.
Q5: What is the minimum order quantity (MOQ) for a trial order?
A: One drum (180 kg) for sample evaluation. For regular commercial orders, MOQ is 4 drums (720 kg) or one IBC tote (approx. 935 kg). Larger bulk orders (ISO tank) are also available.
Q6: Can you ship internationally?
A: Yes. We provide professional export services, flexible packaging, and global shipping solutions for industrial customers.
