3-Aminopropanol Usage And Synthesis

Chemical Properties

clear colourless to very slightly yellow liquid

Uses

Organic intermediate.

Uses

3-Amino-1-propanol is used in the production of anionic emulsifiers, nonionic polyethylene emulsions. Its salts such as hydrochloride, nitrate, sulfate, phosphate are used for the balanced curing action with selected textile resins. It is used as a starting material in the preparation of beta-lactam antibiotics, humectants for foods and cosmetics. It acts as a corrosion inhibitor and finds application in water treatment, metal treatment and absorption of carbon dioxide gas.

Uses

3-Amino-1-propanol was used in the synthesis of di-tert-butyl aminopropanol derivative.

Definition

ChEBI: 3-aminopropan-1-ol is a member of the class of propanolamines that is propane with a hydroxy substituent at C-1 and an amino substituent at C-2, making it both a primary amine and a primary alcohol. It is a primary alcohol, a primary amine and a propanolamine.

General Description

Colorless to pale yellow liquid with a fishy odor. Less dense than water. Melting point 12.4°C (54°F). Moderately toxic by ingestion.

Air & Water Reactions

Water soluble.

Reactivity Profile

3-Aminopropanol neutralizes acids to form salts plus water in an exothermic reaction. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Reacts with strong reducing agents, such as hydrides to generate flammable gaseous hydrogen.

Hazard

Irritant to tissue.

Health Hazard

If inhaled may be harmful. Contact may cause burns to skin and eyes. (Organic base.)

Flammability and Explosibility

Non flammable

Safety Profile

Moderately toxic by ingestion and skin contact. An experimental teratogen. A severe skin and eye irritant. Combustible when exposed to heat or flame; 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 AMINES.
