2-METHYLPENTANE Chemical Properties,Usage,Production

Definition

ChEBI: 2-Methylpentane is an alkane.

General Description

Colorless liquid. Isomers (2-methyl, 3-methyl) are possible and present in technical mixtures or singly for research purposes. Used in organic synthesis and as a solvent.

Air & Water Reactions

Highly flammable. Easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Insoluble in water.

Reactivity Profile

2-METHYLPENTANE may be incompatible with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted material and nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, burns exothermically.
