Oxidation technology

In terms of organic chemistry, oxidation is defined as a reaction which causes carbon to lose electron density. This can be caused by a carbon atom forming a bond with a more electronegative atom (e.g. oxygen, nitrogen), or breaking a bond with a less electronegative atom (e.g. hydrogen).


Hydrogenolysis technology

Hydrogenolysis is a reaction where hydrogen is added to a compound and breaks that compound’s bonds, forming two molecules as a result. Johnson Matthey's DAVY™ hydrogenolysis technology reacts hydrogen gas (H2) with a vapour-phase carbonyl compound.
