What is Dibutylamine?
Dibutylamine (CAS 111-92-2), commonly abbreviated as DBA, is a secondary aliphatic amine.
Where is Dibutylamine used?
- Rubber and polymer processing: accelerator and cross-linking agent in vulcanization and resin cure systems
- Agrochemicals: building block for herbicide and fungicide synthesis
- Corrosion inhibitors: pH buffering and metal surface protection in industrial fluids
- Personal care: neutralizing agent and intermediate for emulsifiers and conditioning actives
- It serves as a catalyst and curing agent.
Good to know: Controlled reactivity with acid chlorides and isocyanates is critical for these applications and formulations.
Commercial specifications
- Purity typically 99% and upward
- COA, SDS, and purity confirmation by GC analysis with each shipment
