Octadecanamine Structural

What is Octadecanamine?

Chemical properties

White prills

The Uses of Octadecanamine

Octadecylamine is used in biological studies for the formation of ion pairing as alternative to improve encapsulation and stability and to reduce skin irritation of retinoic acid loaded in solid lipid nanoparticles.

The Uses of Octadecanamine

Octadecylamine is used to surface functionalize different carbon nanomaterials (graphene oxide, carbon nanotubes) for different applications which include thin film nanocomposite (TFN) nanofilteration and carbon fiber microelectrodes. It can be used for the preparation of butyrylcholinesterase/stearylamine films (Langmuir-Blodgett films) for use in enzymatic field effect transistor (ENFET) based biosensors. Octadecylamine also forms films which can be used in ion exachnge systems. It may also be used in the preparation of metal oxide nano crystals with controlled size and shape.

The Uses of Octadecanamine

Octadecylamine (ODA) is used:

  • To induce hydrophobicity in nanodiamond (ND) powders.
  • In the surface modification of graphite and fullerenes.
  • As a dual source of carbon and nitrogen in the synthesis of N-doped carbon nanotubes (CNTs).
  • To synthesize a single-chain cationic surfactant, bis(amidoethylcarbamoylethyl) octadecylamine.

What are the applications of Application

Octadecylamine is used to grow nanocrystals

Definition

ChEBI: An 18-carbon primary aliphatic amine.

Production Methods

Octadecylamine is manufactured under the trade names of Adogen 142D (Ashland), Alamine 7D (General Mills), Armeen 18D (Armak), Kemamine P- 990D (Humko), and Jetamine 18D (Jetco).

General Description

A white solid. 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

Octadecanamine 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

ACUTE/CHRONIC HAZARDS: Exposure to Octadecanamine may cause sensitization of the skin.

Fire Hazard

Octadecanamine is combustible.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. A skin irritant. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.
