| Reactivity Profile | 1,2-PROPYLENEDIAMINE 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. |
| Chemical Dangers | Decomposes on burning. This produces toxic fumes including nitrogen oxides. The substance is a strong base. It reacts violently with acid and is corrosive. Reacts with acid anhydrides, acid chlorides and strong oxidants. |
| Brandbekämpfung | Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]:Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. |
| Erste-Hilfe-Maßnahmen | Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention. |
| Freisetungsmaßnahmen | · CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. |
| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.General First Aid: |
| Sichere Lagerung | Fireproof. Separated from food and feedstuffs, strong oxidants, acids, acid anhydrides and acid chlorides. Well closed. Store in an area without drain or sewer access. |
| Expositionsschutz und Persönliche Schutzausrüstung | · Wear positive pressure self-contained breathing apparatus (SCBA). |
| Freisetung ohne Brand | Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]: |
| Verschüttetes entsorgen | Remove all ignition sources. Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. |
| Isolation and Evacuation | Excerpt from ERG Guide 132 [Flammable Liquids - Corrosive]:Immediate precautionary measure |
| Eye Prevention | Wear face shield or eye protection in combination with breathing protection. |
| Fire Prevention | NO open flames, NO sparks and NO smoking. NO contact with oxidizing agents. Above 33 °C use a closed system, ventilation and explosion-proof electrical equipment. |
| Inhalation Risk | A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C. |

Anwendungen & Verwendung
Beschreibung
1,2-Diaminopropane is a colorless liquid that is very hygroscopic and miscible with water and most organic solvents. It forms azeotropes with butanol, 2-methylpropanol, and toluene and has a strong ammoniacal odor.
Verwenden
1,2-Diaminopropane was used as model precursor in the electron induced deposition of amorphous carbon nitride films.
