| | 1,8-Diaminooctane Usage And Synthesis |
| 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 | Nonflammable | | 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.] |
