Application

Ethylcyclohexane can be used as:
  • A model for alkyl-substituted cycloalkanes to study their rate coefficients of reaction with OH radicals and Cl atoms.
  • A model for light hydrocarbons to investigate their catalytic cracking performance.
  • An organic monomer precursor to synthesize organic-inorganic hybrid polymer thin films by plasma enhanced chemical vapor deposition.
