Synthesis and industrial production
Formaldehyde was first
reported by the
Russian chemist
Aleksandr Butlerov (1828–86) and was conclusively identified by
August Wilhelm von Hofmann.
[7]
Formaldehyde is produced industrially by the catalytic oxidation of
methanol. The most common catalysts are
silver metal or a mixture of an
iron and
molybdenum or
vanadium oxides. In the more commonly used FORMOX process methanol and oxygen react at ca. 250–400 °C in presence of iron oxide in combination with molybdenum and/or vanadium to produce formaldehyde according to the
chemical equation:
[2]
- 2 CH3OH + O2 → 2 CH2O + 2 H2O
The silver-based catalyst usually operates at a higher temperature, about 650 °C. Two chemical reactions on it simultaneously produce formaldehyde: that shown above and the
dehydrogenation reaction:
- CH3OH → H2CO + H2
In principle formaldehyde could be generated by oxidation of
methane, but this route is not industrially viable because the formaldehyde is more easily oxidized than methane.
