Chemical Name: 3-Methyl-2-Butanone Synonyms: Methyl isopropyl ketone, MIPK CAS Number: 563-80-4 Appearance: Clear, colorless liquid Odor: Sweet, acetone-like Uses: Solvent roles in coatings, adhesives, cleaning products, and some chemical syntheses
Hazard Class: Flammable liquid, irritant Signal Word: Warning Health Risks: Eye, skin, and respiratory irritation; narcotic effects like dizziness at high vapor levels Fire Risks: High flammability; vapors can travel along surfaces and ignite at a distance Chronic Exposure: Repeated contact can lead to skin dryness or cracking
Main Ingredient: 3-Methyl-2-Butanone Purity: Often encountered at high concentrations, with trace impurities from manufacturing Relevant Impurities: Sometimes low levels of other ketones or alcohols can be present
Inhalation: Move person to fresh air; give oxygen if breathing is difficult Skin Contact: Wash with soap and water; remove contaminated clothing Eye Contact: Rinse thoroughly with water for several minutes; seek medical advice if irritation lingers Ingestion: Rinse mouth, avoid inducing vomiting; seek medical attention promptly
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide Unsuitable Media: Direct water stream may spread fire Hazardous Combustion Products: Carbon monoxide and carbon dioxide may form Firefighting Advice: Use full protective gear and self-contained breathing apparatus Special Risks: Containers may explode if heated; cool with plenty of water
Personal Protections: Wear gloves, goggles, and appropriate protective clothing Ventilation: Increase airflow to control vapor buildup Spill Cleanup: Absorb with inert material like sand, keep away from ignition sources, use non-sparking tools Environmental Handling: Prevent runoff into waterways; notify local authorities if contamination is likely
Handling Precautions: Keep containers tightly closed; avoid breathing vapors; use in well-ventilated areas No Smoking Policy: Mandatory in handling areas due to fire risk Storage: Store in a cool, dry, well-ventilated location, away from sparks and direct sunlight Compatibility: Separate from oxidizers, acids, and other reactive chemicals
Exposure Limits: Occupational exposure limits apply; consult local regulations for specific values Engineering Controls: Local exhaust or general room ventilation to maintain airborne levels below recommended limits Protective Equipment: Chemical goggles, flame-resistant gloves, lab coat or coveralls Respiratory Protection: Half-face or full-face respirator may be required in poorly ventilated spaces
Boiling Point: Around 92°C Flash Point: About 14°C Vapor Pressure: Moderate volatility at room temperature Solubility: Limited mixing with water, soluble in organic solvents Density: Slightly lighter than water Evaporation Rate: Similar to methyl ethyl ketone, so it disappears quickly when exposed to air
Stability: Stable under ordinary conditions when handled properly Incompatible Materials: Strong oxidizing agents, acids, bases Hazardous Reactions: May react violently with incompatible materials, releasing hazardous gases Decomposition Products: Burning creates carbon oxides and possibly other toxic vapors
Routes of Exposure: Inhalation, skin absorption, eye contact, ingestion Short-Term Effects: Respiratory and skin irritation, headache, drowsiness, dizziness Long-Term Effects: Repeated exposure may cause dermatitis or other skin problems Acute Toxicity: Larger doses can depress the central nervous system Carcinogenicity: Not classified as a known or suspected carcinogen
Aquatic Toxicity: Harmful to aquatic life if allowed to reach waterways Persistence: Moderate biodegradability Bioaccumulation: Low potential in organisms Environmental Precautions: Prevent further leakage or spillage if safe to do so; avoid release to soil and water
Waste Methods: Dispose of contents and container in accordance with local, regional, and national regulations Incineration: Common method for hazardous solvents Precautions: Never pour down the drain or release to environment
Classification: Regulated for transport due to fire risk Packing Group: Usually assigned based on flash point and quantity Special Precautions: Label clearly; keep containers tightly closed; make sure packaging is secure
Workplace Regulation: Listed as a hazardous chemical in chemical safety and health laws Labelling: Requirements include flammable liquid and irritant hazard pictograms Use Constraints: Restrictions may apply for industrial and consumer products containing the solvent
