Phenol CAS 108-95-2

What is Phenol CAS 108-95-2?

Molecules and physicochemical parameters

Molecular formula: C₆H₅OH

Molecular weight: 94.11

Appearance: Colorless needle-like crystals (pure product), oxidizing to pink to red when exposed to air for a long time.

Melting and boiling points: Melting point 40-42°C, boiling point 181.9°C.

Solubility

Slightly soluble in water at room temperature (about 8.3g /100g), and miscible with water above 65°C.

It is readily soluble in organic solvents such as ethanol, ether, chloroform and glycerol.

Acidity and alkalinity: Weakly acidic (pKa≈10), stronger than alcohols but weaker than carbonic acid, and can form sodium phenolate with NaOH.

Characteristics and Reactions

Color development reaction: It turns purple when encountering ferric chloride (FeCl₃) (a characteristic reaction of phenolic hydroxyl groups).

Substitution reaction: It forms a white precipitate of 2,4, 6-tribromophenol with bromine water (qualitative detection).

Oxidizing property: Slowly oxidizes to quinones in the air, and the color deepens.


Phenol CAS 108-95-2 Use

Industrial synthesis

Resin manufacturing: Producing phenolic resin (bakelite) and epoxy resin (accounting for more than 50% of global consumption).

Chemical intermediates: Synthesis of bisphenol A (raw material for polycarbonate), caprolactam (monomer of nylon-6), salicylic acid (precursor of aspirin).

Solvents and additives: Extraction solvents in petroleum refining, rubber anti-aging agents.

Pharmaceuticals and daily chemicals

Disinfectant: 1-5% solution is used for disinfecting instruments, and 0.5% is used for preserving biological preparations.

Skin medication

1% solution for relieving itching; 2% ointment for treating fungal infections (such as tinea manus and pedis);

Apply a 95% solution locally to remove spots (neutralization with ethanol for anti-corrosion purposes is required).

Special preparation: Phenol iodochlorogel (phenol + iodoform + calcium chloride) is used for non-surgical sterilization of women (success rate 90.38%).

Scientific Research and Agriculture

Analytical reagents: Colorimetric method for detecting nitrates and metal ions.

Pesticide synthesis: Production of herbicides (such as 2,4-D) and insecticides.


Phenol CAS 108-95-2 safety

Health hazard

Acute toxicity

The oral LD₅₀ of rats was 317 mg/kg, and the lethal dose for humans was approximately 1 g/kg.

Inhalation of vapor causes pulmonary edema, and skin contact leads to necrosis (corrosive at concentrations above 20%).

Chronic effects: Long-term exposure leads to liver and kidney function damage and dermatitis. IARC classifies it as a Group 3 carcinogen (possibly carcinogenic).

Operation protection

Essential equipment: Gas mask, chemical protective glasses, anti-corrosion gloves (made of nitrile), gas suit.

Leakage treatment

A small amount: After adsorption, the sand and soil should be disposed of as hazardous waste.

In large quantities: Build embankments, cover with foam to prevent evaporation, and prohibit direct water flushing.

Storage requirements

Cool and well-ventilated (≤35℃), away from light and moisture (humidity ≤80%);

Incompatible substances: Strong oxidants, strong acids, strong bases (to prevent violent reactions).
