Chemical Name: Sodium Butoxide
Chemical Formula: NaOC4H9
Common Forms: Often encountered as a white to off-white powder or granule
Uses: Organic synthesis, a strong base in laboratory reactions, catalyst in the manufacturing of various chemicals
Synonyms: Sodium n-butoxide, sodium butylate
Hazard Classes: Corrosive to skin and eyes, severe irritant to mucous membranes
Physical Hazards: Reacts vigorously with water, liberates heat and butanol vapor
Environmental Hazards: Harmful to aquatic life because of alkalinity
Signal Word: Danger
Pictograms: Corrosive, exclamation mark (for irritation)
Component: Sodium Butoxide
Chemical Purity: Typically above 95%, depending on supplier
CAS Number: 2372-45-4
Hazardous Impurities: Trace sodium hydroxide and butanol possible due to hydrolysis during transportation or storage
Inhalation: Get person to fresh air promptly, keep them warm and at rest, seek medical attention for respiratory symptoms like coughing or difficulty breathing
Skin Contact: Remove contaminated clothing, rinse skin with lukewarm running water for at least 15 minutes, watch for delayed irritation
Eye Contact: Immediately and thoroughly flush eyes with water for 20 minutes, lifting eyelids, get medical help
Ingestion: Rinse mouth, do not induce vomiting, give small amounts of water if conscious, get prompt medical attention
Symptoms: Burning pain, blistering, redness, possible delayed tissue damage for skin and eyes; respiratory irritation for inhalation; nausea for ingestion
Flammability: Sodium butoxide itself does not burn, but it generates highly flammable butanol when reacting with water
Extinguishing Media: Dry chemical powder or sand recommended, do not use water or foam
Special Hazards: Product releases heat and butanol vapor under fire conditions
Protective Equipment: Full protective clothing and self-contained breathing apparatus required for responders
Hazardous Byproducts: Sodium oxide, butanol vapors, possibly toxic organic fumes under combustion
Personal Precautions: Wear respiratory protection, chemical-resistant gloves, goggles, and protective garments
Environmental Precautions: Avoid discharge into drains, surface water, or soil
Cleanup Methods: Use dry, non-combustible absorbent like sand, collect in containers for disposal, ventilate area well, prevent contact with water in cleanup
Decontamination: Wash spill site once all material gathered, check tools and equipment before re-use
Handling: Work in well-ventilated area or fume hood, avoid breathing dust or vapor, prevent skin and eye contact, do not mix with water or acids
Storage: Store in tightly closed containers made of compatible material such as stainless steel, keep cool and dry in exclusion from moisture, do not store with acids, oxidizers or water-reactive substances
Additional Recommendations: Label storage area clearly, keep emergency washing facilities nearby, inspect container integrity regularly
Engineering Controls: Use local exhaust ventilation or chemical fume hood for laboratory work
Eye Protection: Chemical safety goggles and face shield
Hand Protection: Gloves made of nitrile, neoprene, or butyl rubber
Clothing: Long sleeves, lab coat, apron preferred for splash protection
Respiratory Protection: Approved respirators for dust or vapor possible exposure
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing promptly
Appearance: White to light yellow powder
Odor: Characteristic, mild, ether-like (from butanol impurity or decomposition)
Melting Point: Decomposes before melting, no well-defined melting point
Boiling Point: Not applicable
Solubility: Decomposes in water with vigorous reaction
Vapor Pressure: Not significant at ambient conditions
pH: Alkaline
Other: Reacts violently with acids and water
Chemical Stability: Stable under dry, cool conditions and inert atmosphere
Conditions to Avoid: Moist air, water exposure, high humidity, contact with acidic materials
Incompatible Materials: Acids, water, oxidizers, halogenated compounds
Hazardous Decomposition: Butanol, sodium hydroxide, potentially dangerous organic vapors with strong acids or heat
Routes of Exposure: Skin/eye contact, inhalation, ingestion
Acute Toxicity: Moderate toxicity by ingestion, severe irritation/corrosion to eyes and skin
Chronic Effects: Prolonged exposure could cause skin damage, sensitivity, or respiratory discomfort
Potential Symptoms: Burning, redness, blisters on skin; severe eye pain and possible permanent injury; respiratory distress if inhaled
Carcinogenicity: Not classified as carcinogenic under IARC, NTP, or OSHA
Other Effects: No significant reproductive or mutagenic data available
Aquatic Toxicity: High alkalinity can affect aquatic organisms
Persistence and Degradability: Hydrolyzes rapidly in water to form butanol and sodium hydroxide
Bioaccumulation: No data indicating significant bioaccumulation
Mobility in Soil: Degrades rapidly, but spillage can raise soil pH and damage plants and microorganisms
Precautions: Prevent release to water bodies to avoid environmental harm
Waste Treatment: Neutralize cautiously with a dilute acid under controlled conditions
Contaminated Packaging: Rinse with compatible solvents before disposal, follow hazardous waste protocols
Disposal Methods: Dispose through licensed hazardous waste contractor, comply with local, regional, and national waste regulations
Precautions: Avoid releases to sewers, soils, or natural waterways
Hazard Class: Classified as dangerous good for ground, air, and sea transport
Packaging: Use approved drums or metal containers with moisture-proof sealing
Labeling: Corrosive materials, with appropriate warning symbols
Special Precautions: Keep away from all sources of water during transit, transport with other compatible substances only
Local Regulation: Subject to regulations concerning storage and handling of corrosive and water-reactive substances
International Standards: Aligned with UN dangerous goods classification for transport, covered under chemical safety and environmental laws
Workplace Safety: Employers required to provide safety training and access to MSDS for staff
Reporting Requirements: Report sizable spills or accidental releases to environmental/control authorities
Restricted Uses: Certain uses may be subject to permit depending on local chemical safety legislation
