Monoethanolamine (MEA 99%min, CAS 141-43-5) is a colourless viscous alkaline liquid with an ammonia-like odour. It is miscible with water and alcohols. This industrial‑grade material features high purity and low impurities. Mainly applied for gas sweetening, surfactant synthesis, pH adjustment and metal-working treatment. Packed in 200 kg steel drums, store in cool dry ventilated place, keep away from air due to carbon-dioxide absorption.
