2,3-DIMETHYLBUTANE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

General Description

A clear colorless liquid with a petroleum-like odor. Flash point -20°F. Less dense than water and insoluble in water. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Saturated aliphatic hydrocarbons, such as 2,3-DIMETHYLBUTANE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. 2,3-DIMETHYLBUTANE is incompatible with oxidizing materials. 2,3-DIMETHYLBUTANE is also incompatible with oxygen. .

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
