Overview
Ethanolamine (MEA) is a primary amine and alcohol, belonging to the amino alcohol family. It is a clear, viscous liquid with a mild ammonia-like odor, widely produced via the reaction of ethylene oxide with ammonia. Its bifunctional nature (amine and hydroxyl groups) makes it a versatile intermediate in industrial and commercial applications. MEA is a cornerstone in gas treatment, particularly for removing acidic gases like CO2 and H2S from natural gas streams. Its low cost, high reactivity, and regenerative properties in scrubbing systems contribute to its dominance in this sector.
Physical and Chemical Properties
Ethanolamine exhibits hygroscopicity, readily absorbing moisture from the air. Its alkaline nature (pKa ~9.5) allows it to neutralize acids, forming salts. The compound’s miscibility with water and polar solvents enhances its utility in formulations requiring homogeneous mixtures. Thermal stability is moderate, with decomposition occurring above 200°C. MEA reacts exothermically with acids, anhydrides, and oxidizing agents, necessitating careful handling. Its viscosity and surface tension are critical in applications like emulsifiers and lubricants.
Main Applications
In gas processing, MEA-based "amine scrubbing" is a benchmark for acid gas removal due to its high absorption capacity. The chemical is also a key ingredient in detergents and personal care products, where it acts as a pH adjuster and emulsifier. Pharmaceuticals leverage MEA as a precursor for antihistamines and local anesthetics. Industrial uses include corrosion inhibitors in boilers and metalworking fluids. Emerging applications span agrochemicals and CO2 capture technologies, driven by environmental regulations.
Safety and Storage
MEA is corrosive and causes severe skin/eye burns. Proper PPE (gloves, goggles, respirators) is mandatory. Spills should be neutralized with weak acids (e.g., vinegar) and contained to prevent environmental release. Storage requires corrosion-resistant containers (stainless steel or polyethylene) in cool, ventilated areas. Incompatibilities include strong acids, copper alloys, and aluminum. Regulatory compliance (OSHA, GHS) mandates hazard labeling and SDS availability.
B2B Procurement Guide
Bulk buyers should prioritize suppliers with transparent purity assays (≥99% for industrial use) and adherence to ISO 9001 or similar standards. Packaging options range from 200L drums to ISO tank containers for large quantities. Regional pricing fluctuates with ethylene oxide feedstock costs. Long-term contracts may offer stability. Verify logistics capabilities (ADR/RID for transport) and supplier track record in handling hazardous chemicals.
