What is Hexylamine?

Chemical properties

colourless liquid

Chemical properties

Colorless to yellow liquid; fishy aroma.

Chemical properties

n-Hexylamine is a colorless, flammable liquid, slightly soluble in water and soluble in alcohol and ether.

The Uses of Hexylamine

1-Hexylamine is used as corrosion inhibitors, emulsifiers and surfactants. It is used in dyes, rubber and pharmaceutical industries. It is also used to study the modification of alkanethlol monolayers in gas-phase surface reactions. It acts as an initiator in the ring opening polymerization of N-carboxyanhydride.

The Uses of Hexylamine

n-Hexylamine is used in organic syntheses.

The Uses of Hexylamine

Toxic by ingestion, inhalation, and skin absorption. Flammable, moderate fire risk.

Definition

ChEBI: A 6-carbon primary aliphatic amine.

Aroma threshold values

High strength odor; fishy type, recommend smelling in a 0.10% solution or less

General Description

A water-white liquid with an amine-like odor. Flash point 85°F. Boiling point 132°F. Less dense than water and poorly soluble in swater. Hence floats on water. May be toxic by inhalation, ingestion or skin absorption.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

HEXYLAMINE neutralize acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Flammability and Explosibility

Flammable

Purification Methods

Dry with, and fractionally distil the hexylamine from, KOH or CaH2. Store away from CO2. [Beilstein 4 IV 709.]
