Methanol to formaldehyde reaction
Web28 sep. 2012 · The partial conversion of methanol (MeOH) to formaldehyde (HCHO) in the gas chromatograph (GC) injection port was studied. The presence of formaldehyde in … Formaldehyde was first reported in 1859 by the Russian chemist Aleksandr Butlerov (1828–86) In his paper, Butlerov referred to formaldehyde as "dioxymethylen" (methylene dioxide) [page 247] because his empirical formula for it was incorrect (C4H4O4). It was conclusively identified by August Wilhelm von Hofmann, who first announced the production of formaldehyde by passing methanol vapor in air over hot platinum wire. With modifications, Hoffmann's method remains th…
