Chemistry & Engineering

Reaction EquationDehydrohalogenation
ThermodynamicsExothermic
Catalyst SystemNaOH
Reactor ClassBatch reactor
Process ConsiderationsDGEBA is the standard resin. Cures with amines.

Extraterrestrial Production Pattern

  1. BPA + epichlorohydrin reaction with NaOH catalyst
  2. Two-step process: addition then dehydrochlorination
  3. Molecular weight control by stoichiometry
  4. Curing with amines, anhydrides, or other hardeners

Applications

  • Structural adhesives
  • Protective coatings
  • Composite matrix (carbon fiber, fiberglass)
  • Electronics encapsulation

**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.)
