Hydrogen Peroxide

Molecular Structure

Molecular Details

Molecular Formula	H₂O₂
Molecular Weight	34.01 g/mol
State	Liquid at standard conditions

Olefinverbund Integration

Chemistry & Engineering

Reaction Equation	Anthraquinone Auto-oxidation (AO) Loop
Thermodynamics	Overall H₂ + O₂ → H₂O₂ is exothermic
Catalyst System	Palladium (hydrogenation step)
Reactor Class	Hydrogenator (Fluidized/Fixed) and Oxidizer (Bubble column)
Process Considerations	AO working solution is recycled.

Extraterrestrial Production Pattern

1. Anthraquinone process: hydrogenation → oxidation cycle
2. H₂ + anthraquinone → hydroquinone (Pd catalyst)
3. Hydroquinone + O₂ → anthraquinone + H₂O₂
4. Extraction, purification, and concentration

Applications

• Pulp and paper bleaching
• Chemical synthesis oxidizer
• Water treatment
• Rocket propellant (high concentration)

Reaction Diagram

Overall Reaction: H2 + O2 -> H2O2 (via anthraquinone)

Unit Operations

Process steps following chemical engineering unit operation principles:

Step	Operation	Description
1	Working Solution Prep	Dissolve ethylanthraquinone in organic solvent
2	Hydrogenation	Pd catalyst, reduce EAQ to EAQH₂
3	Filtration	Remove catalyst from working solution
4	Oxidation	Air oxidation of EAQH₂ to EAQ + H₂O₂
5	Extraction	Extract H₂O₂ into water
6	Concentration	Vacuum distillation to 35-70% H₂O₂

**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.)
