(organic compound) An organic compound, (CH3CHO). Sometimes called ethanal or acetic aldehyde. See aldehyde.
(organic compound) The simplest aldehyde, HCHO, a colourless gas that has many industrial applications; it dissolves in water to give formol (10%) and formalin.
Acetic aldehyde. See Aldehyde.
A colorless, volatile liquid, H2CO, resembling acetic or ethyl aldehyde, and chemically intermediate between methyl alcohol and formic acid.
a colorless volatile water-soluble liquid aldehyde used chiefly in manufacture of acetic acid and perfumes and drugs
a colorless poisonous gas; made by the oxidation of methanol
Ethanal (common name acetaldehyde) is an organic chemical compound with the formula CH3CHO, sometimes abbreviated by chemists as MeCHO (Me = methyl). It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.
Formaldehyde ( (listen) fer-mal-duh-hahyd, also (listen) for-) (systematic name methanal) is a naturally occurring organic compound with the formula CH2O (H−CHO). The pure compound is a pungent-smelling colorless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin).
