1,5-HEXADIENE Usage And Synthesis

Chemical Properties

clear colorless to slightly yellow liquid

Uses

1,5-Hexadiene is used to study the Pd(II)-catalyzed cycloisomerization of functionalized 1,5-hexadienes.

Definition

Although not a fragrance material, this hydrocarbon may occasionally be used as part of industrial masking odours, and it may also appear as an impurity in various perfume chemicals.

Production Methods

1,5-Hexadiene is produced from Allylbromide and Sodium (or Magnesium).

Application

1,5-Hexadiene plays an important role in organic synthesis. Since it contains two double bonds in its molecule, it can participate in a variety of addition reactions, polymerization reactions, etc., making it possible to synthesize complex organic molecules. For example, it can be used as a biaxial chain growth reagent for the synthesis of polymer materials such as polyolefins and polystyrene, contributing to the development of materials science.

Flammability and Explosibility

Not classified

Purification Methods

Distil 1,5-hexadiene from NaBH4. [Beilstein 1 IV 1013.]

Toxics Screening Level

The initial threshold screening level (ITSL) for 1,5-hexadiene is 264 μg/m3 based on an annual averaging time.
