Pyrolysis in the Presence of Additional Reactants or with Catalysts

7 Pyrolysis in the Presence of Additional Reactants or with Catalysts. 

Pyrolytic reactions, mainly for analytical purposes, are commonly done in a helium atmosphere. Sometimes these reactions are done, intentionally or not, in the presence of additional reactants or in the presence of catalysts. The most common additional reactants are probably oxygen, hydrogen, water, and quaternary N-alkyl (or aryl) ammonium hydroxides. Oxygen from the air and water are sometimes unintentionally present during pyrolysis. The presence of an additional reactant can modify the result of the pyrolytic reaction.
