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

The
Hazard fields
include
special hazard alerts
air and water
reactions, fire hazards, health hazards, a reactivity profile, and
details about
reactive groups assignments
and
potentially incompatible absorbents.
The information in CAMEO Chemicals comes from a variety of
data sources.
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
No information available.
Health Hazard
No information available.
Reactivity Profile
ALUMINUM ALKYLS are strong reducing agents. React violently with water, alcohols, phenols, amines, carbon dioxide, sulfur oxides, nitrogen oxides, halogens, and halogenated hydrocarbons, creating fire and explosion hazards [Handling Chemicals Safely 1980. p. 929].
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents
No information available.

data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
