General Description
A clear colorless liquid. Not a single compound ("alkyl" refers to a family of substitutent groups). Most probably either trimethyl aluminum or triethyl aluminum.
Hazards
Reactivity Alerts
- Strong Reducing Agent
- Water-Reactive
- Pyrophoric
Air & Water Reactions
Highly flammable. May ignite upon contact with air producing aluminum oxide fumes. Reacts violently with water to give aluminum oxide and alkanes (flammable hydrocarbons).
Fire Hazard
