2,5-Norbornadiene Chemical Properties,Uses,Production

Chemical Properties

Clear colorless to slightly yellow liquid

Uses

Intermediate in prostaglandin synthesis.1

General Description

A colorless liquid. Insoluble in water and less dense than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. When heated will polymerize and at decomposition emits acrid smoke and irritating fumes.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

2,5-NORBORNADIENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions. Violent explosions at low temperatures in ammonia synthesis gas units have been traced to the addition products of dienes and nitrogen dioxide [Bretherick, 5th Ed., 1995].

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

Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. Mildly toxic by inhalation. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Purify the diene by distillation from activated alumina [Landis & Halpern J Am Chem Soc 109 1746 1987]. [Beilstein 5 IV 879.]
