| | 1,2-Diaminopropane Usage And Synthesis |
| Chemical Properties | clear liquid | | Uses | In conjunction with cupric sulfate it is a very sensitive reagent for mercury. | | Uses | 1,2-Diaminopropane was used as model precursor in the electron induced deposition of amorphous carbon nitride films. | | Definition | ChEBI: A diamine that is propane substituted by amino groups at positions 1 and 2. Propylenediamine is commonly used as a bidentate ligand in the formation of coordination complexes. | | General Description | A colorless liquid with an ammonia-like odor. Flash point 160°F. Density 0.87 g / cm3. Boiling point 243°F. Strongly irritates skin and tissue. | | Air & Water Reactions | Very hygroscopic. Very soluble in water. | | Reactivity Profile | 1,2-Diaminopropane 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. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. | | 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. | | Flammability and Explosibility | Flammable | | Safety Profile | Moderately toxic by
ingestion, sktn contact, and subcutaneous
routes. A corrosive irritant to eyes, skin, and
mucous membranes. Dangerous fire hazard
when exposed to heat, flames, oxidizers. To
fight fire, use alcohol foam. When heated to
decomposition it emits toxic fumes of NOx.
Used as an intermedate in production of
petroleum and polymer additives, and
surfactants. See also AMINES. | | Purification Methods | Purify the diamine by azeotropic distillation with toluene. Then distil it. Store it in a CO2 free atmosphere. [Horton et al. Anal Chem 27 269 1955, Beilstein 4 IV 1255.] |
