2-METHYL-1-BUTENE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Uses

Organic synthesis, pesticide formulations.

Uses

2-Methyl-1-butene is used as a solvent in organic synthesis. It is also used in the preparation of pinacolone, flavor enhancer, spice, crop protectants and tertiary amyl phenol. Further, it serves as a photosensitive material and concrete dispersant. In addition to this, it is used as a fuel and fuel additive.

Definition

ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 2.

General Description

A colorless volatile liquid with a disagreeable odor. Insoluble in water and less dense than water. Flash point below 0°F. Vapors are heavier than air. Used to make other chemicals.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

The unsaturated aliphatic hydrocarbons, such as 2-METHYL-1-BUTENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. In the presence of various catalysts (such as acids) or initiators, compounds in this class can undergo very exothermic addition polymerization reactions.

Hazard

Highly flammable, dangerous fire and explosion risk.

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.

Safety Profile

A simple asphyxiant. Very dangerous fire hazard when exposed to heat, flame, or oxidizers. To fight fire, use dry chemical, CO2, foam. When heated to decomposition it emits acrid smoke and irritating fumes.
