1,4,7,10,13-Pentaazatridecane Usage And Synthesis

Chemical Properties

colourless to green-yellow viscous liquid

Chemical Properties

Tetraethylenepentamine is a yellow, viscous liquid.

Uses

Solvent for sulfur, acid gases, and various resins and dyes; saponifying agent for acidic materials; manufacture of synthetic rubber; dispersant in motor oils; intermediate for oil additives.

General Description

A viscous liquid. Slightly less dense than water. Vapors heavier than air. Corrosive to the eyes, skin, mouth, throat and stomach. Vapors irritate the eyes and corrosive to the upper respiratory tract. Vapors may irritate the eyes. Flash point 325°F.

Air & Water Reactions

Soluble in water. Hygroscopic.

Reactivity Profile

1,4,7,10,13-Pentaazatridecane is hygroscopic. 1,4,7,10,13-Pentaazatridecane can react with oxidizing materials and strong acids. 1,4,7,10,13-Pentaazatridecane may attack some forms of plastics.

Hazard

Strong irritant to eyes and skin.

Health Hazard

Inhalation may cause nausea and slight irritation; compound is a sensitizer, and prolonged contact may cause asthma. Ingestion can cause burns of mouth, esophagus, and possibly stomach. Contact with eyes or skin may cause burns. Repeated skin contact may cause dermatitis.

Fire Hazard

Special Hazards of Combustion Products: Ammonia and toxic oxides of nitrogen may form in fires.

Safety Profile

Poison by ingestion and intravenous routes. Moderately toxic by skin contact. Mutation data reported. A corrosive irritant to skin, eyes, and mucous membranes. Combustible when exposed to heat or flame. Can react with oxidizing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.

Potential Exposure

Tetraethylenepentamine is used as a solvent for resins and dyes, in manufacture of synthetic rubber; and intermediate for oil additives; in papermaking.

Shipping

UN2320 Tetraethylenepentamine, Hazard class: 8; Labels: 8-Corrosive material.

Purification Methods

Distil the amine under vacuum. Also purify via its penta hydrochloride, nitrate or sulfate. Jonassen, Frey and Schaafsma [J Phys Chem 61 504 1957] cooled a solution of 150g of the base in 300mL of 95% EtOH, and added dropwise 180mL of conc HCl, keeping the temperature below 20o. The white precipitate was filtered off, crystallised three times from EtOH/water, then washed with diethyl ether and dried by suction. Reilley and Holloway [J Am Chem Soc 80 2917 1958], starting with a similar solution cooled to 0o, added slowly (keeping the temperature below 10o) a solution of 4.5g-moles of HNO3 in 600mL of aqueous 50% EtOH (also cooled to 0o). The precipitate was filtered by suction, recrystallised five times from aqueous 5% HNO3, then washed with acetone and absolute EtOH and dried at 50o. [For purification via the sulfate see Reilley and Vavoulis (Anal Chem 31 243 1959), and for an additional purification step using the Schiff base with benzaldehyde see Jonassen et al. J Am Chem Soc 79 4279 1957]. [Beilstein 4 IV 1244.]

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. This chemical is strongly alkaline; reacts with acids.
