Chemical Name: 1-Propyl-3-Methylimidazolium Dihydrogen Phosphate
CAS No.: 464927-84-2
Concentration: 100% (pure substance)
Impurities: Trace levels of water or other ionic contaminants may exist, non-hazardous in typical laboratory grades
Inhalation: Move the person to fresh air, keep comfortable for breathing. Seek medical advice if symptoms arise.
Skin Contact: Wash affected area with plenty of soap and water, remove contaminated clothing. If irritation develops, seek medical attention.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing. Obtain medical advice if irritation persists.
Ingestion: Rinse mouth with water, do not induce vomiting. Call a poison center or doctor for guidance if feeling unwell or in any doubt.
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or CO2.
Specific Hazards: Thermal decomposition produces toxic phosphorus oxides, nitrogen oxides, and carbon oxides.
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus required to prevent exposure to combustion by-products.
Advice for Firefighters: Approach fire from upwind, avoid smoke inhalation, use standard firefighting techniques for chemical hazards.
Personal Precautions: Wear proper chemical-resistant gloves, goggles, lab coat, and respirator if necessary. Evacuate unnecessary personnel from area.
Environmental Precautions: Prevent further leakage or spillage if safe, avoid release into drains and natural water bodies.
Methods for Cleanup: Absorb spill with inert material such as dry sand or diatomaceous earth, collect and place in containers for proper disposal. Clean area thoroughly with water after material removal.
Safe Handling: Handle only in well-ventilated areas, minimize generation of vapors and contact with material, avoid inhaling dust or mist, wash hands and face after use, keep away from incompatible substances.
Storage Conditions: Keep container tightly closed and stored in a cool, dry, well-ventilated place, store away from strong oxidizers, acids, and moisture sources. Keep out of reach of children.
Incompatible Materials: Avoid contact with strong bases, oxidizing agents, moisture, and strong acids due to possible hazardous reactions.
Exposure Limits: No specific occupational exposure limits established for this compound.
Engineering Controls: Use adequate ventilation such as chemical fume hood, maintain low vapor concentrations in air.
Personal Protective Equipment: Chemical resistant gloves (nitrile recommended), safety goggles, laboratory coat, appropriate respiratory protection if ventilation is inadequate.
Hygiene Measures: Wash thoroughly after handling, remove and wash contaminated clothing, avoid eating or drinking in areas where chemical is handled.
Physical State: Liquid (may solidify at lower temperatures)
Color: Colorless to pale yellow
Odor: Slight, characteristic
pH (aqueous solution): Acidic, typically < 3
Melting Point: 45–60°C (dependent on water content)
Boiling Point: Decomposes before boiling
Solubility: Miscible with water and polar organic solvents
Density: Approx. 1.23 g/cm3 at 20°C
Vapor Pressure: Very low at room temperature, non-volatile
Flash Point: >150°C
Partition Coefficient (Log Kow): Practically not available, expected to be low due to ionic nature
Chemical Stability: Stable under recommended storage and handling conditions, sensitive to high temperatures and strong heat sources.
Reactivity: Can react with strong oxidizing or reducing agents. Acidic, reacts with bases.
Hazardous Decomposition Products: Thermal decomposition may release phosphoric acid, carbon oxides, nitrogen oxides, and other irritating fumes.
Conditions to Avoid: Avoid excessive heat, direct sunlight, and contact with incompatible materials.
Acute Toxicity: Limited data available, expected to have low acute oral and dermal toxicity for mammals based on similar ionic liquids.
Skin Corrosion/Irritation: Can cause moderate skin irritation on prolonged or repeated contact.
Serious Eye Damage/Irritation: Causes serious but reversible eye irritation on contact.
Respiratory Tract Irritation: Inhalation of mist or vapor may cause irritation.
Chronic Effects: Not classified as carcinogenic, mutagenic, or reproductive toxin based on current available data.
Sensitization: No evidence for skin or respiratory sensitization found in available literature.
Ecotoxicity: Ionic liquids can be toxic to aquatic organisms if released in high concentrations. No specific acute or chronic aquatic toxicity data for this compound, but general caution applies due to phosphate content.
Persistence and Degradability: Breaks down slowly in the environment, not readily biodegradable.
Bioaccumulation: Low potential for bioaccumulation predicted because of high water solubility and ionic nature.
Mobility in Soil: Slightly mobile in wet soils due to solubility, may leach to groundwater.
Other Adverse Effects: Spills can alter local pH and phosphate levels, affecting water bodies' nutrient balance.
Waste Disposal Methods: Dispose of contents and containers in accordance with local, regional, national, and international regulations. Avoid discharge to sewers or surface water bodies.
Contaminated Packaging: Empty containers should be rinsed, rendered unusable, and sent for recovery or to suitable hazardous waste disposal.
Special Precautions: Involve hazardous waste contractor for bulk quantities, do not incinerate in open air, always check up-to-date regional waste codes.
