Gas Treatment

For amine scrubbing processes to selectively remove CO₂ and H₂S from natural gas, refinery gas, and synthesis gas (gas sweetening)

pH Regulator

Mild alkali for pH adjustment in water treatment and chemical processing

Agrochemicals Intermediate

Synthesis of certain herbicides and as a salt former to increase the water solubility of active ingredients in fertilizer and crop protection formulations

Detergents & Soap Intermediate & Surfactant

Reacts with fatty acids to form alkanolamide surfactants and MEA soaps, which are used as emulsifiers, detergents, and dispersing agents in cleaning products

pH Adjuster/Neutralizer

Neutralizes acidic components in hair dyes, creams, and lotions, providing a stable emulsion and modifying viscosity

Storage Conditions

Store in tightly closed containers in a cool, dry, and well-ventilated area, away from incompatible materials

Protection

Moisture (highly hygroscopic) and CO2 (reacts to form a solid carbonate salt, leading to caking or reduced purity)

Shelf Life Note

Due to its corrosive nature, storage vessels are often made of stainless steel or carbon steel, or high-density polyethylene (HDPE)
