N,N-Dipropyl-1-propanamine Usage And Synthesis

Chemical Properties

colourless liquid

Chemical Properties

Colorless to fishy liquid; mild fishy aroma.

Uses

Tri-n-propylamine is used as an chemical intermediate, organic solvent. It is used in the preparation of chemical compounds such as dyes, drugs, catalyst & other uses. It is used together with ruthenium in the electrochemiluminescence.

Uses

Oxo feed stock, lubricant additive, plasticizers, nonyl phenol.

Definition

ChEBI: A tertiary amine that is ammonia in which each hydrogen atom is substituted by a propyl group.

Production Methods

Tripropylamine is manufactured by reacting propanol and ammonia in the presence of dehydrating catalysts; by reacting n-propyl chloride and ammonia under pressure; or by the action of acetone and ammonia.

Aroma threshold values

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

General Description

A water-white liquid. Flash point near 125°F. Less dense than water. May be mildly toxic by ingestion and inhalation. Used as a solvent.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

N,N-Dipropyl-1-propanamine is incompatible with oxidizing agents . 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

Exposure can cause irritation of eyes, nose and throat. Toxic by inhalation or ingestion.

Fire Hazard

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as nitrogen oxides and carbon monoxide, may be formed when involved in fire.

Flammability and Explosibility

Flammable

Safety Profile

Poison by ingestion. Moderately toxic by skin contact and inhalation. A corrosive irritant to skin, eyes, and mucous membranes. Flammable when exposed to heat, flame, or oxidizers. Can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx. See also MINES.

Purification Methods

Dry the amine with KOH and fractionally distil it. Also reflux it with toluene-p-sulfonyl chloride and with KOH, then fractionally distil it. The distillate, after additon of 2% phenyl isocyanate, was redistilled and the residue fractionally distilled from sodium. [Takahashi et al. J Org Chem 52 2666 1987, Beilstein 4 IV 470.]
