Acetaldehyde |
Description: |
Acetaldehyde CAS number 75-07-0 Molecular formula C2H4O Molar mass 44.05 g mol?1 Appearance Colourless liquid Pungent, fruity odor Density 0.788 g cm?3 Melting point ?123.5 °C, 150 K, -190 °F Boiling point 20.2 °C, 293 K, 68 °F Solubility in water soluble in all proportions Viscosity ~0.215 at 20 °C Use:Traditionally, acetaldehyde was mainly used as a precursor to acetic acid. This application has declined because acetic acid is made more efficiently from methanol by the Monsanto and Cativa processes. In terms of condensation reactions, acetaldehyde is an important precursor to pyridine derivatives, pentaerythritol, and crotonaldehyde. Urea and acetaldehyde combine to give a useful resin. Acetic anhydride reacts with acetaldehyde to give ethylidene diacetate, a precursor to vinyl acetate, which is used to produce polyvinyl acetate.
