Key physicochemical properties
Appearance and Odor: p-Isopropylphenol is a white crystalline solid at room temperature; it has an aromatic yet slightly pungent odor.
Melting and Boiling Points: Melting point 71–73°C; atmospheric boiling point approximately 335°C (189–191°C/1.33 kPa under reduced pressure).
Solubility: Readily soluble in organic solvents such as methanol and acetone; sparingly soluble in water.
Flash Point: 160°C; classified as a combustible solid.
Key Application Areas
Polymer additives: Widely used as molecular weight regulators and end-capping agents for epoxy resins and polycarbonates, as well as modifiers for phenolic resins.
Surfactant raw materials: Reacted with ethylene oxide to produce alkylphenol-based non-ionic surfactants, commonly used as emulsifiers for pesticides.
Bactericides and fungicides: Exhibit good affinity for mineral oils and serve as bactericides and fungicides for lubricating oils; also used for wood preservation due to low toxicity (compared to pentachlorophenol) and the absence of irritating odors.
Safety, Storage, and Transportation
Hazardous characteristics: Under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), isopropylphenol is classified as an irritant (Xi); it can cause skin and severe eye irritation and may cause respiratory tract irritation.
Toxicological data: The oral LD50 in rats is approximately 2400 mg/kg. Contact with the skin in a high-temperature molten state may cause mild injury.
Operational protection: Avoid inhaling dust or contact with skin and eyes. It is recommended to wear chemical safety glasses and nitrile gloves.
Storage requirements: Store sealed in a cool, dry and ventilated place, away from strong oxidants, acid chlorides and acid anhydrides.
FAQ
Q: Toxicity and Occupational Health
A:Primary hazards: Phenolic corrosion + skin sensitization.
Acute: Oral LD₅₀ in mice is 875 mg/kg (moderately toxic); causes severe irritation to eyes, skin, and the respiratory tract; the liquid causes serious eye damage (H318) and skin burns (H314, Skin Corr. 1B).
Chronic/Allergic: Can be absorbed through the skin; repeated exposure causes dermatitis; GHS classifications include H334 (respiratory sensitization) and H312 (harmful in contact with skin).
No independent IARC carcinogenicity classification; however, long-term exposure to phenols requires monitoring for potential liver and kidney strain.
Occupational exposure: No specific Chinese PC-TWA value established; managed by analogy to "phenols." It is recommended to strictly control workshop dust/vapor levels within the 1–5 mg/m³ range.
Q: Key Points for Handling and Storage
A: Closed-system operation with local exhaust ventilation to prevent dust dispersion (solid substance prone to sublimation, releasing trace vapors);
PPE: Chemical-resistant goggles and face shield, butyl or neoprene gloves, and chemical-resistant protective clothing; bare-handed handling is strictly prohibited;
Storage: Keep sealed in a cool, dry place (2–8°C preferred) and away from light; store separately from strong oxidizers, acid anhydrides, acyl chlorides, and strong bases (phenolic hydroxyl groups form salts with bases; while the isopropyl group provides significant steric hindrance, bond cleavage may still occur at high temperatures);
Spills: Collect via wet sweeping or inert absorbent materials; dispose of as phenol-containing hazardous waste through a qualified incineration facility (equipped with flue gas de-phenolation);
Firefighting: Use water spray, dry chemical powder, CO₂, or sand/earth; thermal decomposition produces CO, phenolic fumes, and hydrocarbons; firefighters require SCBA.
