1,4-PENTADIENE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Uses

1,4-Pentadiene can be used to obtain bioinsecticidal composition.

General Description

A colorless liquid. Less dense than water and insoluble in water. Hence floats on water.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

1,4-PENTADIENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen. Can undergo exothermic polymerization reactions in the presence of various catalysts (such as acids) or initiators. May undergo autoxidation upon exposure to the air to form explosive peroxides. Violent explosions have occurred at low temperatures in ammonia synthesis gas units. These explosions have been traced to the decomposition of addition products between dienes such as this one and oxides of nitrogen [Bretherick, 1995].

Health Hazard

Vapor may cause dizziness or suffocation. Contact may irritate skin and eyes.

Purification Methods

Distil it from NaBH4. Purify it by preparative gas chromatography or distillation and stabilize it with 0.1% of 2,6-di-tert-butyl-p-cresol. [Reimann et al. J Am Chem Soc 108 5527 1986, Beilstein 1 IV 998.]
