Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH3CHO, sometimes abbreviated by chemists as MeCHO (Me = methyl). It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being … See more Acetaldehyde was first observed by the Swedish pharmacist/chemist Carl Wilhelm Scheele (1774); it was then investigated by the French chemists Antoine François, comte de Fourcroy and Louis Nicolas Vauquelin (1800), … See more Tautomerization of acetaldehyde to vinyl alcohol Like many other carbonyl compounds, acetaldehyde See more Traditionally, acetaldehyde was mainly used as a precursor to acetic acid. This application has declined because acetic acid is produced … See more • Alcohol dehydrogenase • Disulfiram-like drug • Formaldehyde • Paraldehyde • Wine fault See more In 2003, global production was about 1 million tonnes. Before 1962, ethanol and acetylene were the major sources of acetaldehyde.

WebThe pH of the solution is adjusted to about 4 - 5, because this gives the fastest reaction. The solution will contain hydrogen cyanide (from the reaction between the sodium or potassium cyanide and the sulphuric acid), but still contains some free cyanide ions. This is important for the mechanism. WebThe rate constant for the decomposition of acetaldehyde, CH 3 CHO, to methane, CH 4, and carbon monoxide, CO, in the gas phase is 1.1 × × 10 −2 L mol −1 s −1 at 703 K and 4.95 L mol −1 s −1 at 865 K.
