3-Diethylaminopropylamine Usage And Synthesis

Chemical Properties

clear colorless to slightly yellowish liquid

Uses

Curing agent for epoxy resins, intermediate.

Uses

3-Diethylaminopropylamine is used as a solvent, extraction agents and organic synthesis intermediates, dyes, pigments, surface active agent.

Uses

3-(Diethylamino)propylamine may be used in the preparation of:

• Biocompatible polyampholyte-coated (poly(acrylic acid)-co-3-(diethylamino)-propylamine magnetite nanoparticles (PAMNPs).
• Hyaluronic acid grafted with 3-diethylaminopropyl (DEAP) group (HA-g-DEAP) nanoparticles for use as a drug delivery vehicle.
• DEAPA-modified poly(vinyl alcohol) (PVA) polymers that can be employed in gene silencing.

It may also be used to introduce cationic groups during the surface modification of microfibrillated cellulose (MFC).

General Description

A water-white liquid with a fishlike odor. Flash point 138°F. May be very irritating to skin and eyes. Used to make other chemicals and as a component of adhesives.

Air & Water Reactions

Flammable.

Reactivity Profile

3-Diethylaminopropylamine 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.

Hazard

Moderate fire risk. Irritant to skin.

Health Hazard

May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Safety Profile

Moderately toxic by ingestion and skin contact. Corrosive to the eyes, skin, and mucous membranes. A sensitizer. See also AMINES. Flammable liquid when exposed to heat or flame; can react with oxidzing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
