C2H5OH oxidation

Thus, both processes of H202 dissociation and C2H5OH oxidation proceed in two stages general intermediate (Chance) complex formation responsible for chemical conjugation in the system and Oguri complex formation, which induces the one-stage synthesis of the final oxidation products. 

Ethanol C2H5OH oxidizes in a multistep process in solution to acetaldehyde.

An example of propellant tailoring is the fuel used to launch the first U. S. satellite into orbit. The original fuel for the launch vehicle was ethyl alcohol. MAF-4 (also known as hydyne or U-DETA), a mixture of 60% UDMH and 40% diethylenetriamine (DETA), was formulated to simulate the physical properties of C2H5OH but provide the increased propellant performance (using liquid oxyen as the oxidizer) requirements of the mission.

Two-electron oxidation of the substrate (i.e. H202 and C2H5OH) in one stage. 

In the [E—OOH C2H5OH] complex ligand OOH is the electron acceptor particle, whereas ligand C2H5OH (DH2 in the general shape) is the electron donor. Their interaction regenerates active sites of catalase, produces H20 and oxidizes the substrate.
