Phenol

Molecular Structure

Molecular Details

Molecular Formula	C₆H₅OH
Molecular Weight	94.11 g/mol
State	Solid/Liquid at standard conditions

Olefinverbund Integration

Chemistry & Engineering

Reaction Equation	Cumene + O₂ → Cumene Hydroperoxide → Phenol + Acetone
Thermodynamics	Autoxidation is exothermic; Cleavage is strongly exothermic
Catalyst System	Sulfuric acid for cleavage
Reactor Class	Oxidation tower followed by acid cleavage unit
Process Considerations	The Hock process couples Phenol and Acetone production efficiently.

Extraterrestrial Production Pattern

1. Benzene + propylene → cumene (alkylation)
2. Cumene oxidation → cumene hydroperoxide
3. Acid-catalyzed cleavage → phenol + acetone
4. Distillation for separation and purification

Applications

• Bisphenol A for polycarbonate and epoxy
• Phenolic resins (Bakelite)
• Caprolactam (for nylon 6)
• Pharmaceuticals and disinfectants

Reaction Diagram

Overall Reaction: C6H5CH(CH3)2 + O2 -> C6H5OH + CH3COCH3

Unit Operations

Process steps following chemical engineering unit operation principles:

Step	Operation	Description
1	Cumene Oxidation	Bubble air through cumene at 80-130°C to form CHP
2	Concentration	Concentrate cumene hydroperoxide to 80%
3	Acid Cleavage	Decompose CHP with H₂SO₄ at 60-80°C
4	Neutralization	Neutralize acid with NaOH or phenol
5	Crude Separation	Separate phenol/acetone from α-methylstyrene
6	Phenol Purification	Distill to >99.9% phenol purity

**Key S88 Concepts:**
- **Process Cell**: The physical grouping containing all equipment for this process
- **Unit**: The major equipment that performs the synthesis
- **Equipment Modules**: Individual pieces of equipment (reactors, columns, etc.)
- **Unit Procedure**: The sequence of operations to produce the product
- **Phases**: The lowest level of procedural control (e.g., REACT, SEPARATE, PURIFY)

Key S88 Concepts:
• Process Cell: Physical grouping containing all equipment
• Unit: Major equipment performing synthesis
• Equipment Modules: Individual pieces (reactors, columns, etc.)
• Phases: Lowest level of procedural control (REACT, SEPARATE, etc.)
