Phenol

Phenol is an aromatic organic compound with the molecular formula C6H6O and a molecular weight of 94.11 g/mol. It consists of a benzene ring with a hydroxyl group (-OH) attached directly to it. This white crystalline solid is highly toxic and corrosive, classified as a dangerous substance with mutagenic properties. Phenol is widely used in industrial applications but requires careful handling due to its hazardous nature and ability to cause severe chemical burns.

Phenol is a white crystalline solid at room temperature with a distinctive sweet, medicinal odor. It has a melting point of 40.5°C and a boiling point of 181.7°C. The compound is moderately soluble in water (about 8.3 g/100 mL at 20°C) and highly soluble in alcohol and ether. Phenol is hygroscopic, meaning it absorbs moisture from air, and can turn pink or red upon exposure to light and air due to oxidation.

Phenol is primarily used as an intermediate in the production of plastics, particularly phenolic resins and polycarbonates. It serves as a raw material for manufacturing bisphenol A, which is essential for epoxy resins and polycarbonate plastics. Additionally, phenol is used in the production of pharmaceuticals, dyes, explosives, and as a disinfectant in industrial applications. It also finds use in the synthesis of various organic compounds and as a laboratory reagent.

Phenol requires strict safety measures due to its corrosive and toxic nature. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, face shield, and protective clothing covering all skin. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Avoid direct skin contact as phenol can cause severe chemical burns and is readily absorbed through skin. Use appropriate tools for handling and ensure emergency shower and eyewash stations are accessible.

Phenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage temperature should remain below 40°C to prevent melting. Keep away from strong oxidizing agents, alkalis, and reactive metals. Containers must be made of compatible materials such as glass or specific plastics. Storage areas should be equipped with appropriate spill control measures and access should be restricted to trained personnel only.

Phenol contact requires immediate emergency response due to its corrosive nature. For skin contact, immediately remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes, then seek medical attention. If phenol contacts eyes, irrigate immediately with water for at least 15 minutes and get medical help. In case of inhalation, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention. Always contact emergency services for significant exposure.

Phenol disposal must comply with local and international hazardous waste regulations due to its toxic and corrosive properties. It cannot be disposed of with regular waste or poured down drains. Small quantities can be neutralized and incinerated at authorized hazardous waste facilities with appropriate emission controls. Large quantities require collection by licensed hazardous waste disposal companies. Always consult local environmental authorities for specific disposal requirements and maintain proper documentation of waste disposal activities.

Phenol is classified under ADR regulations as Class 6.1 (Toxic substances) Packing Group II, indicating its high toxicity level. Transportation requires appropriate hazardous goods packaging, labeling with GHS pictograms (GHS05, GHS06, GHS08), and proper shipping documentation. Vehicles must display appropriate hazard placards and drivers need hazardous materials certification. Packages must be secured to prevent spillage and emergency response information must accompany shipments. Only authorized carriers experienced in dangerous goods transport should handle phenol shipments.

Phenol is subject to extensive regulatory oversight under multiple frameworks including REACH, CLP, and various national regulations. It requires safety data sheets and hazard communication due to its classification as Acute Tox. 3, Skin Corr. 1B, Muta. 2, and STOT RE 2. Although not currently listed as an SVHC (Substance of Very High Concern), its mutagenic properties make it subject to strict handling and reporting requirements. Industrial users must comply with occupational exposure limits and environmental discharge regulations.

Phenol is available through OYSI, a specialized European distributor of industrial chemicals serving the professional market. As a regulated hazardous substance, phenol can only be sold to qualified industrial users who demonstrate appropriate handling capabilities and safety measures. OYSI provides technical support, safety documentation, and ensures compliance with European chemical regulations. Purchase requires proper business credentials and adherence to end-use restrictions.
