2-(Butylamino)ethanol (CAS 111-75-1) is an organic compound with the formula CH₃(CH₂)₃NHCH₂CH₂OH:
A secondary amino alcohol featuring a butyl group (–C₄H₉) attached to the nitrogen and a hydroxyethyl group (–CH₂CH₂OH).
Systematic name: N-Butylethanolamine.
Physical State: Colorless to yellow liquid, amine-like odor.
Solubility: Miscible with water and organic solvents (e.g., ethanol, acetone).
Basicity: Moderate (pKa ~9.5–10) due to the amine group.
Boiling Point: ~202°C (396°F).
Surfactants & Emulsifiers:
Raw material for zwitterionic surfactants (e.g., betaines) used in personal care products.
Corrosion Inhibitors:
Component in industrial coolants and metalworking fluids.
Chemical Synthesis:
Intermediate for agrochemicals, dyes, and rubber additives.
Gas Treating:
CO₂ scrubbing in natural gas processing.
Irritant: Causes skin/eye burns and respiratory irritation.
Flammable: Combustible liquid (flash point ~85°C/185°F).
Handling: Use PPE (gloves, goggles) and adequate ventilation.
Summary: A versatile industrial intermediate valued for dual amine/alcohol reactivity. Mainly used in surfactants and corrosion inhibitors.
