1,6-HEXANEDIAMINE Chemical Properties,Uses,Production

Chemical Properties

White to cream solid


ChEBI: A C6 alkane-alpha,omega-diamine.

General Description

A clear colorless liquid. Burns although some effort is required to ignite. Soluble in water. Corrosive to metals and tissue. Produces toxic oxides of nitrogen during combustion. Used to make nylon.

Air & Water Reactions

Water soluble.

Reactivity Profile

HEXAMETHYLENEDIAMINE is hygroscopic. Can react with strong oxidizing materials. Incompatible with acids, acid chlorides and acid anhydrides. Also incompatible with ketones, aldehydes, nitrates, phenols, isocyanates, monomers and chlorinated compounds .

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Contact allergens

Hexamethylenediamine is used with adipic acid in the synthesis of polyamide plastics.

Purification Methods

Crystallise it in a stream of nitrogen. It sublimes in a vacuum. [Beilstein 4 IV 1320.]
