Chemical Properties
Colorless to fishy liquid; mild fishy aroma.
Chemical Properties
colourless liquid
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.]
