Chemical Properties
clear colourless to very slightly yellow liquid
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
Organic intermediate.
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.
Synthesis
The production of 3-aminopropanol mainly adopts the way of hydrogenation reduction, among which, the industrialized production and catalytic hydrogenation synthesis is the main way, among which, hydroxypropionitrile is the raw material, ammonia is the solvent, Raney's nickel is the catalyst, and the hydrogenation under high temperature and low pressure is the main production process for the preparation of 3-aminopropanol, the conversion rate of the hydroxypropionitrile hydrogenation is as high as 99% and the recovery rate of 3-aminopropanol is more than 90%. In this process, the conversion rate of hydroxypropionitrile hydrogenation is as high as 99%, and the recovery rate of 3-aminopropanol is above 90%. However, the process has the problem of troublesome separation of by-products, and the purity of 3-aminopropanol can only reach over 99% by at least the process of removing water, removing ammonia, removing by-products and distillation.
