Synthesis and industrial production
Formaldehyde was first reported (http://en.wikipedia.org/wiki/Chemical_synthesis) by the Russian (http://en.wikipedia.org/wiki/Russia) chemist Aleksandr Butlerov (http://en.wikipedia.org/wiki/Aleksandr_Butlerov) (1828–86) and was conclusively identified by August Wilhelm von Hofmann (http://en.wikipedia.org/wiki/August_Wilhelm_von_Hofmann).<sup id="cite_ref-6" class="reference">[7] (http://en.wikipedia.org/wiki/Formaldehyde#cite_note-6)</sup>
Formaldehyde is produced industrially by the catalytic oxidation of methanol (http://en.wikipedia.org/wiki/Methanol). The most common catalysts are silver (http://en.wikipedia.org/wiki/Silver) metal or a mixture of an iron (http://en.wikipedia.org/wiki/Iron_oxide) and molybdenum (http://en.wikipedia.org/wiki/Molybdenum_trioxide) or vanadium (http://en.wikipedia.org/wiki/Vanadium_pentoxide) oxides (http://en.wikipedia.org/wiki/Oxide). 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 (http://en.wikipedia.org/wiki/Chemical_equation):<sup id="cite_ref-Ullmann_1-1" class="reference">[2] (http://en.wikipedia.org/wiki/Formaldehyde#cite_note-Ullmann-1)</sup>
<dl><dd>2 CH<sub>3</sub>OH + O<sub>2</sub> → 2 CH<sub>2</sub>O + 2 H<sub>2</sub>O</dd></dl> 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 (http://en.wikipedia.org/wiki/Dehydrogenation) reaction:
<dl><dd>CH<sub>3</sub>OH → H<sub>2</sub>CO + H<sub>2</sub></dd></dl> In principle formaldehyde could be generated by oxidation of methane (http://en.wikipedia.org/wiki/Methane), but this route is not industrially viable because the formaldehyde is more easily oxidized than methane.
