Chemistry & Engineering

Reaction Equation	C₆H₁₂ + O₂ → Cyclohexanone/Cyclohexanol (KA Oil)
Thermodynamics	Exothermic oxidation
Catalyst System	Cobalt naphthenate
Reactor Class	Air oxidation reactor
Process Considerations	Low conversion per pass to maximize selectivity.

Extraterrestrial Production Pattern

1. Cyclohexane + O₂ → cyclohexanol + cyclohexanone (KA oil)
2. Co or Mn catalyst at 150-160°C

**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.)
