Chemical Name: Sodium Phenoxide
Synonyms: Sodium Phenate
Chemical Formula: C6H5ONa
CAS Number: 139-02-6
Appearance: White to light beige crystals or powder
Odor: Faint phenolic smell
Solubility: Dissolves readily in water and alcohol, releases phenol odor when dissolved
Physical State: Solid
Hazard Class: Corrosive
Health Risks: Can damage eyes, skin, and respiratory tract; targets liver and kidneys if absorbed in substantial quantities
Acute Effects: Irritation, severe burns, respiratory issues if dust inhaled
Chronic Effects: Repeated exposure harms the nervous system and can damage organs
Combustion Hazard: Releases toxic fumes such as carbon monoxide, carbon dioxide, and sodium oxide when burning
Main Component: Sodium Phenoxide — upwards of 98% concentration
Impurities: May include sodium hydroxide in trace amounts, residual phenol sometimes present
Physical Form: Typically a crystalline powder, sometimes in chunk form if exposed to moisture
Eye Contact: Rinse with water for at least 15 minutes, keep eyelids open; seek medical care
Skin Contact: Rinse off immediately with running water, remove contaminated clothes, never rub affected area
Inhalation: Move to fresh air and get medical attention; symptoms like coughing or difficulty breathing need urgent care
Ingestion: Rinse mouth, avoid vomiting, and seek emergency medical treatment quickly; do not give anything by mouth if unconscious
Suitable Extinguishers: Dry chemical, foam, or carbon dioxide
Unsafe Extinguishers: Water spray may cause splattering of corrosive substance
Hazardous Combustion: Burns give off caustic vapors as well as phenolic compounds
Firefighting Gear: Full protective suit and positive pressure self-contained breathing apparatus are essential
Risks: Dust can form explosive mixtures if conditions support it
Personal Protection: Use splash-proof goggles, chemical-resistant gloves, and a dust mask or respirator
Spill Cleanup: Shovel solid material into dry, suitable containers for disposal; use damp methods to minimize dust
Ventilation: Work in a well-ventilated area, use local exhaust if available
Environmental Precautions: Never allow material to enter drains, sewers, or waterways
Handling: Avoid breathing dust and direct contact; minimize exposure with tight-fitting personal protective gear
Hygiene: Wash hands thoroughly before eating, drinking, or touching skin
Storage: Keep container tightly closed, store in a cool, dry, and well-ventilated area; avoid sources of ignition
Incompatible Materials: Store away from acids, oxidizers, and moisture
Engineering Controls: Local exhaust ventilation should be used to control airborne dust
Protective Gear: Chemical splash goggles, nitrile gloves, lab coat, and suitable mask or respirator
Exposure Limits: OSHA and ACGIH do not list a specific exposure limit for sodium phenoxide, but keeping airborne concentrations to a minimum is wise
Workplace Monitoring: Regular checks of air quality where product is handled or processed
Appearance: Off-white to yellowish powder
Odor: Phenol-like
pH Value: Strongly alkaline in solution
Melting Point: Starts to decompose before melting; exact melting point not sharply defined
Boiling Point: Decomposes before boiling
Solubility: Highly soluble in water
Stability: Absorbs water and carbon dioxide from air; forms phenol and sodium carbonate over time
Stability: Tends to degrade in the presence of moisture and carbon dioxide
Reactivity: Reacts vigorously with strong acids, gives off phenol fumes in acidic environments
Incompatible Substances: Acids, oxidizers, water (if anhydrous form handled)
Hazardous Decomposition: Fumes of phenol, sodium carbonate, and toxic oxides on heating or combustion
Routes of Exposure: Inhalation, skin contact, ingestion
Acute Effects: Burns, tissue destruction on contact, nausea, headache if inhaled
Chronic Effects: Prolonged or repeated exposure links to liver and kidney damage, neurotoxic symptoms
Sensitization: Can cause allergy in sensitive individuals
Toxicity Data: Oral LD50 in rats for phenol reported at around 340 mg/kg; sodium phenoxide acts similarly due to rapid conversion back to phenol in the body
Aquatic Toxicity: Harmful to fish and aquatic organisms, causes long-term changes in water quality
Persistence: Breaks down slowly in the environment, increases pH where released
Bioaccumulation: Does not tend to bioaccumulate in larger animals due to rapid breakdown
Disposal Guidance: Spilled material should never be directed into soil or waterways without proper treatment
Method: Place unwanted or contaminated product in sealed chemical waste containers
Disposal Site: Send to approved hazardous waste facility equipped for corrosive chemicals
Do Not: Flush down the drain, burn in open air, or mix with household trash
Cleanup Residue: Neutralize small residues with weak acid under controlled conditions before final disposal
Shipping Name: Sodium Phenoxide
Transport Hazard Class: Corrosive solid
UN Number: 2923
Packing Group: II
Labeling Requirements: Corrosive pictogram, emergency response marking
Transport Cautions: Protect from moisture and physical damage; segregate from acids and oxidizers
Regulated Status: Handled as a hazardous substance under international transport codes
Workplace Regulations: U.S. OSHA, European REACH, and similar bodies require robust chemical safety practices for handling
Environmental Rules: Most jurisdictions restrict uncontrolled discharge or dumping; disposal at licensed facility required
Worker Protections: Safety training, supply of emergency showers, eye wash stations, and full PPE mandatory in regulated workplaces
