Description

clear colorless to light yellow viscous liquid

2-propanolamine appears as a colorless to pale yellow liquid with a fishy odor. Moderately toxic by ingestion and skin contact. A severe skin irritant. Combustible. The compound contains both the amine group -NH2 and the alcohol group -OH and so has some properties of both. Floats and mixes with water. (USCG, 1999)

Isolation and Evacuation：

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Nonfire Spill Response：

Neutralizing Agents for Acids and Caustics: Cover spilled material with sodium bisulfate. Flush with water. (USCG, 1999)

Personal Protective Equipment：

Wear butyl rubber gloves and face shield or all-purpose canister respirator for spills. Wear self-contained breathing apparatus and full protective clothing for fires. (USCG, 1999)

Drug Information

Health Hazards：

If inhaled may be harmful. Contact may cause burns to skin and eyes. (Organic base.) (USCG, 1999)

First Aid：

INHALATION: Move victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. SKIN AND EYES: Immediately flush skin or eyes with running water for at least 15 minutes; hold eyelids open if necessary. Remove and isolate contaminated clothing and shoes. Maintain normal body temperture. (USCG, 1999)

DL-2-Amino-1-propanol Use and Manufacturing

Methods of Manufacturing

DIPEA (5 mmol/eq) was added to a solution of 1-nitro-n-hexane (1 mmol/eq) in acetonitrile at 15°C, maintained under stirring. Freshly distilled trichlorosilane (3.5 mmol/eq) was then added dropwise with a syringe. After leaving under stirring for 18 hours at 15°C, the reaction was quenched by adding 10percent NaOH, and the mixture was extracted with AcOEt. The combined organic phases were dried on NaAbout 300 g of refined glycerol (Superol Brand, PAbout 299 g of refined glycerol (Superol Brand, P
