1,8-Diaminooctane Chemical Properties,Usage,Production

Chemical Properties

white to yellowish solidified crystalline mass

Uses

1,8-Diaminooctane is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.

Definition

ChEBI: 1,8-diaminooctane is an alkane-alpha,omega-diamine in which the two amino groups are separated by eight methylene groups. It derives from a hydride of an octane.

Flammability and Explosibility

Non flammable

Safety Profile

Moderately toxic by ingestion. Asevere skin and eye irritant. When heated todecomposition it emits toxic vapors of NOx.

Purification Methods

Distil the diamine under vacuum in an inert atmosphere (N2 or Ar), cool and store the distillate in an inert atmosphere in the dark. The dihydrochloride has m 273-274o. [Nae & Le Helv Chim Acta 15 55 1955, Beilstein 4 III 612.]
