The '''Formox process''' produces [[formaldehyde]]. Formox is a registered trademark owned by Johnson Matthey.<ref>{{cite web|url=http://www.formox.com|title=Formaldehyde - Johnson Matthey|website=www.formox.com}}</ref> The process was originally invented jointly by Swedish chemical company [[Perstorp Group|Perstorp]] and Reichhold Chemicals .<ref>{{Cite book|url=https://books.google.com/books?id=qoXNBQAAQBAJ&q=formox+perstorp+history&pg=PA132|title=Encyclopedic Dictionary of Named Processes in Chemical Technology|last=Comyns|first=Alan E.|date=2014-02-21|publisher=CRC Press|isbn=9781466567771|language=en}}</ref>
Industrially, formaldehyde is produced by [[Catalysis|catalytic]] [[oxidation]] of [[methanol]]. The most commonly used catalysts are [[silver]] metal or a mixture of an [[iron oxide]] with [[molybdenum]] and/or [[vanadium]]. In the recently more commonly used Formox
:[[methanol|CH<sub>3</sub>OH]] + ½ [[oxygen|O<sub>2</sub>]] → H<sub>2</sub>CO + [[water (molecule)|H<sub>2</sub>O]].
The silver-based catalyst is usually operated at a higher temperature, about 650 °C. On it, two chemical reactions simultaneously produce formaldehyde: the one shown above, and the dehydrogenation reaction:
:[[methanol|CH<sub>3</sub>OH]] → H<sub>2</sub>CO + [[hydrogen|H<sub>2</sub>]]
Further oxidation of the formaldehyde product during its production usually gives [[formic acid]] that is found in formaldehyde solution, found in
