Key Properties
- One of the most water-soluble quaternary ammonium salts
- High phase-transfer catalytic activity, markedly accelerating biphasic reactions
- Hygroscopic — requires sealed, dry storage
- No long alkyl chain; good thermal stability
Applications
- Phase-transfer catalyst in organic synthesis (halogen exchange, N-alkylation, redox, dichlorocarbene reactions)
- Curing accelerator for powder coatings, epoxy and other polymer systems
- Organic electrolyte for electronics; conductive agent for low-temperature aluminium refining
- Zeolite templating agent; modifier for organophilic bentonite and montmorillonite
- Oilfield chemical; precipitant for precious metal separation
Packaging & Storage
Packaging: 25 kg fibre drum or 25 kg waterproof kraft bag; jumbo bags on request.
Storage: Store away from light in a cool, dry, ventilated place. Protect strictly from moisture. Two years shelf life unopened.
Handling & Safety
Hygroscopic and prone to caking. Irritant — avoid dust inhalation and prolonged skin contact.
