N-Butylethanolamine
Overview
N-Butylethanolamine is an organic compound belonging to the ethanolamine family, characterized by both amine and alcohol functional groups. This bifunctional nature makes it a versatile intermediate in specialty chemical synthesis. Industrial production typically involves the reaction of butylamine with ethylene oxide. The compound finds significant use in sectors requiring surface-active properties or nitrogen-containing molecular structures.
Physical and Chemical Properties
As a liquid at room temperature with moderate viscosity, N-Butylethanolamine exhibits both hydrophilic and lipophilic characteristics due to its molecular structure. The compound's boiling point around 212°C makes it suitable for various thermal processes. Chemically, it behaves as both a weak base (amine group) and weak acid (alcohol group), enabling reactions typical of secondary amines and primary alcohols. Its amphoteric nature contributes to surfactant properties when formulated with appropriate counterions.
Main Applications
In industrial applications, N-Butylethanolamine serves as a key building block for corrosion inhibitors, particularly in metalworking fluids and oilfield chemicals. Its molecular structure helps form protective films on metal surfaces. The textile industry utilizes derivatives as softening agents and dye auxiliaries. Other significant uses include production of emulsifiers for agricultural formulations and as intermediates for pharmaceutical active ingredients requiring ethanolamine moieties.
Safety and Storage
Proper handling requires chemical-resistant gloves, eye protection, and adequate ventilation due to potential irritation effects. The compound's flammability necessitates storage away from ignition sources in approved containers. For long-term storage, nitrogen blanketing is recommended to prevent oxidative degradation. Bulk storage tanks should include secondary containment and comply with local regulations for flammable liquids storage.
B2B Procurement Guide
Industrial buyers should prioritize suppliers with ISO 9001 certification and batch-specific certificates of analysis. Technical specifications should confirm purity levels (typically ≥98%) and water content (<0.5%). Transportation considerations include UN proper shipping name 'AMINES, LIQUID, CORROSIVE, N.O.S.' (UN2734). For international shipments, verify compliance with regional chemical regulations such as REACH or TSCA.
