Safety Information
Amino-2-propanol Usage And Synthesis
  • Chemical Propertiescolourless liquid
  • Chemical Properties1-Amino-2-propanol has a fishy odor.
  • OccurrenceReportedly present in sherry.
  • UsesSynthetic and semisynthetic machine lubricating/cutting oil formulations have included isopropanolamine, diisopropanolamine, and triethanolamine, together with nitrites; consequently the EPA has promulgated standards regarding the composition of cutting fluids. No additional uses were found in the literature.
  • DefinitionChEBI: Any amino alcohol that is propan-2-ol substituted by an amino group at position 1.
  • PreparationBy employing Salmonella, mutatant cobD, and aminopropanol
  • Aroma threshold valuesDetection at 28 ppm in water
  • General DescriptionA colorless liquid with a slight ammonia-like odor. Less dense than water and soluble in water. Flash point 165°F. Corrosive to metals and tissue. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Used in plastics, paints, cutting oils, and specialized cleaning compounds.
  • Air & Water ReactionsWater soluble.
  • Reactivity ProfileAmino-2-propanol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
  • Health HazardVapor irritates eyes and nose. Liquid causes local injury to mouth, throat, digestive tract, skin, and eyes.
  • Fire HazardSpecial Hazards of Combustion Products: Irritating vapors generated when heated.
  • Safety ProfilePoison by intraperitoneal route.Moderately toxic by ingestion and skin contact. A skin andsevere eye irritant. Moderately flammable in presence ofheat, flame, sparks, powerful oxidizers. Ignites on contactwith cellulose nitrate of high surface area. C
