What is Diglycolamine?
Diglycolamine (CAS 929-06-6), or DGA, is a bifunctional amine-alcohol.
Where is Diglycolamine used?
- Natural gas and refinery operations: acid gas scrubbing agent that selectively absorbs H2S and CO2 from process streams
- Epoxy and polyurethane: crosslinking and curing agent whose amine group drives network formation
- Water treatment: pH buffering and building block for corrosion inhibitor formulations
- Personal care: neutralizing agent for anionic polymers and acidic actives
- It combines amine and hydroxyl reactivity in one molecule, acting as a curing agent and pH modifier.
Commercial specifications
- High purity concentrations
- Bulk liquid in drums and IBC containers
