Chemical Name: 1-Methyl-1-butylpyrrolidinium trifluoromethanesulfonate
Synonyms: Commonly referred to as an ionic liquid.
Chemical Formula: C10H20F3NO3S
Appearance: This compound shows up as a colorless to pale yellow liquid. Odor stays mild or sometimes goes undetected in open air. Used mostly in electrochemistry and advanced material science.
GHS Classification: Definitely not listed as a major hazardous material, but handling with respect is necessary due to potential eye, skin and respiratory irritation.
Possible Health Hazards: Short, heavy exposure risks irritation of the upper airways, skin, and mucous membranes. Eye contact may cause slight discomfort. Sensitization or allergenic reactions are not commonly reported, though careful observation is recommended in sensitive users.
Environmental Hazards: Not known to be highly toxic to the environment, but persistent ionic liquids can linger in groundwater, so careful waste management matters.
Signal Word: Some regulatory guides use "Warning."
Pictograms: Exclamation mark, covering irritation potential.
Main Ingredient: 1-Methyl-1-butylpyrrolidinium trifluoromethanesulfonate maintains a content of over 98%.
Impurities: Water content and residual organic solvents, if present, stay well below 2% in laboratory-grade samples.
Skin Contact: Rinse affected area with lots of water and soap. Remove contaminated clothing. Skin irritation vanishes in most cases, but mild reactions can still turn up.
Eye Contact: Flush eyes under running water for at least 10 minutes. Lenses should be removed for thorough washing. Medical attention comes in handy if discomfort drags on.
Inhalation: Take fresh air in open space. Symptoms typically resolve quickly in a clean environment.
Ingestion: Rinse mouth, do not force vomiting. Medical attention should be called if large volumes get swallowed.
Suitable Extinguishing Media: Foam, dry powder, and CO2 all do the job. Water spray may work if handled correctly.
Specific Hazards: Decomposition releases toxic fumes such as carbon oxides, sulfur oxides, hydrogen fluoride, and other hazardous byproducts.
Protective Equipment: Firefighters should gear up with self-contained breathing apparatus and chemical-protective gloves.
Personal Protection: Wear gloves and goggles. Avoid inhalation of vapor or mist. Ventilate area quickly.
Cleaning Up: Absorb spillage with inert sand or earth, transferring to chemical waste containers. Rinse contaminated area thoroughly with water.
Environmental Precautions: Prevent leakage into waterways or drains. Collect waste quickly to reduce spread.
Handling: Use in well-ventilated spaces. Spills should get cleaned up directly. Good hygiene practices demand thorough handwashing after use.
Storage: Store in sealed containers at room temperature, away from direct sunlight and moisture. Stay away from incompatible substances like strong oxidizers.
Special Considerations: Eliminate sources of ignition. Reduce static buildup using grounded equipment.
Engineering Controls: Laboratories benefit from fume hoods or spot exhausts.
Personal Protective Equipment: Nitrile gloves, safety glasses, and lab coats offer decent protection.
Respiratory Protection: If vapor or mist builds up, use a suitable respirator with a chemical filter.
Environmental Controls: Reduce chemical waste. Never pour leftovers down household drains.
Appearance: Clear to pale yellow liquid.
Odor: Mild, not offensive.
Melting Point: Ranges near -20°C
Boiling Point: Decomposes before boiling
Solubility: Dissolves well in water and many organic solvents.
Density: Often measured around 1.3 g/cm³ at room temperature.
Viscosity: Significantly higher than water, but pourable.
Chemical Stability: Stable at recommended storage conditions.
Reactivity: Undergoes decomposition at high temperatures and in the presence of strong acids or bases.
Incompatible Materials: Strong oxidizers or reducing agents cause violent reactions.
Hazardous Decomposition Products: Releases toxic gases including hydrogen fluoride and organosulfur compounds when broken down.
Acute Effects: May cause skin and eye irritation. No concrete evidence points to severe toxicity, but tests are limited.
Chronic Effects: Studies on long-term exposure in humans remain sparse. Animal testing points to low systemic toxicity. Inhalation risks stay minimal under normal use.
Sensitization: No robust data on allergic reactions.
Carcinogenicity: No evidence currently classifies it as a carcinogen.
Aquatic Toxicity: Ionic liquids as a group tend to accumulate in water systems. Short-term tests show moderate toxicity to fish and aquatic organisms.
Persistence and Degradability: Degradation occurs slowly. Biodegradation data for this compound suggest environmental persistence.
Bioaccumulative Potential: Not considered highly bioaccumulative given the ionic structure.
Mobility in Soil: Moves easily with water; surface runoff risk follows improper disposal.
Waste Treatment: Dispose through authorized chemical waste handlers. Incineration with proper gas scrubbing preferred.
Do Not: Release into sewers or waterways. Avoid mixing with household waste.
Packaging Disposal: Rinse containers thoroughly before disposal. Follow chemical container protocols.
UN Number: Not usually classified among regulated hazardous goods for land or sea transport.
Packing Group: None assigned for this compound.
Special Transport Precautions: Ship in tightly closed containers. Keep separate from food and feed.
Safety Regulations: Not specifically regulated under most chemical safety laws. General workplace safety rules always apply.
Labelling Requirements: GHS symbols for irritation may be needed by local law. SDS must be readily available for employees.
Environmental Controls: Follow regional guidelines for chemical handling and disposal. Regular training in spill response and first aid builds confidence and keeps workplace accidents low.
