What Di-n-Butylamine is used for
Di-n-butylamine is a colourless liquid with a fishy, ammoniacal odour — the symmetric secondary amine made from two straight-chain butyl groups on one nitrogen. Its higher molecular weight and longer alkyl chains give it a distinctly different property profile from the lighter secondary amines in this family, with a wider boiling range and lower water solubility.
Commercially it earns its place as a corrosion inhibitor, a reagent in the manufacture of emulsifiers, and as a flotation agent used in mineral-processing operations to help separate valuable minerals from ore.
Where it sits among the amines
- Di-n-butylamine (this product) symmetric, straight-chain secondary amine — longer-chain analogue of diethylamine.
- Diisopropylamine the bulky, hindered secondary amine used for LDA and Hunig's base. See that page.
- n-Butylamine the primary amine in the same carbon-chain family. See that page.
Appearance and handling character
Di-n-butylamine is flammable, with a lower overall hazard profile than many lighter amines — it carries a Warning rather than Danger signal word — but still demands standard amine-handling precautions.

How we supply Di-n-Butylamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- Assay confirmed before we quote. Water content and colour matter to downstream flotation and emulsifier performance.
- Dangerous-goods documentation filed correctly. Correctly classified and labelled under UN 2248, Class 3.
- Packing matched to flammable-liquid requirements. UN-approved drums and IBCs.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your production calendar.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.

Flammable, and harmful by inhalation and contact
Di-n-butylamine carries a more moderate hazard profile than many lighter amines. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H226Flammable liquid and vapour.H302Harmful if swallowed.H312Harmful in contact with skin.H332Harmful if inhaled.
Always read the SDS issued with your specific batch. Handle with standard chemical-resistant gloves and adequate ventilation.
Storage
Store in tightly closed containers in a cool, well-ventilated area away from heat, sparks, open flame and oxidisers.
Handling
Use with adequate ventilation. Avoid prolonged skin contact and inhalation of vapour. Ground and bond containers during transfer to control static discharge.
Transport
Ships as UN 2248, Class 3 (flammable liquid). We confirm and document packing group and exact classification for your specific shipment and destination.

Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and dangerous-goods paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How di-n-butylamine is made
Di-n-butylamine is produced industrially by the catalytic amination of n-butanol with ammonia, a route that typically co-produces the full n-butylamine family — mono-, di- and tributylamine — separated by fractional distillation.
We do not publish operating process parameters here; this is background only. Full technical and safety documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
| Chemical family | Secondary aliphatic amine, straight-chain (C8) |
