1-heptene is a chemical compound selected from the group consisting of unsaturated aliphatic hydrocarbon ( specifically, the alkenes).

Occurrence

1-heptene is a product of petroleum distillation and is used as a component in gasoline before. In very small amounts, it is also released in apple, apricot, cherry and plum full of flowering fruit trees.

Use

1-heptene as starting material is used in organic synthesis, for example as a comonomer in the manufacture of polyethylene, in the preparation of linear aldehydes by hydroformylation. Hydroformylation to octanal, followed by reduction to give 1- octanol and dehydrating the 1 -octene is used for the industrial preparation of 1- octene at a scale of 100,000 t / a

Safety

The vapors of 1- heptene combine with air to form an explosive mixture (flash point -8 ° C, ignition temperature 250 ° C).
