Octylamine Usage And Synthesis

Chemical Properties

CLEAR LIQUID

Uses

1-Octylamine is used as a precursor to prepare chemicals. It finds application in functional fluids and as a laboratory reagent. Further, it is used as a reactant in the preparation of 2H-indazoles and 1H-indazolones, which are used as myeloperoxidase(MPO) inhibitors.

Uses

Octylamine is mainly used to synthesize amphiphilic copolymers for polymer coating of quantum dots (QDs) to make them water-soluble.
Other applications:

• Synthesis of 2-cyano-N-octylacetamide by reacting with ethyl cyanoacetate.
• To induce uniformity for synthesizing uniform ultrathin metal sulfide nanostructures.

Definition

ChEBI: An 8-carbon primary aliphatic amine.

Production Methods

Specific uses were not located in the literature. 1-Octylamine is manufactured under the tradenameArmeen8D(Armak).

General Description

A yellow liquid with an ammonia-like odor. Insoluble in water and less dense than water. Hence floats on water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. Used to make other chemicals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

OCTANAMINE neutralizes 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

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.

Flammability and Explosibility
