[PDF] acetic anhydride boiling temperature

L'anhydride acétique ou anhydride éthanoïque est l'anhydride de l'acide acétique; il est obtenu en liant deux molécules d'acide acétique par condensation avec élimination d'eau. L'anhydride acétique dégage des vapeurs irritantes pour les muqueuses WikipédiaFormule : C

  • What happens to acetic anhydride in water?

    * Acetic Anhydride forms Acetic Acid when mixed with WATER.

  • What is the boiling point of anhydride?

    Boiling point
    Ethanoic anhydride boils at 140°C. This is because it is a fairly big polar molecule and so has both van der Waals dispersion forces and dipole-dipole attractions. It does not, however, form hydrogen bonds. That means that its boiling point isn't as high as a carboxylic acid of similar size.
  • After the reaction heating period is over, the excess unreacted acetic anhydride will be destroyed by the addition of water to the mixture: water reacts with acetic anhydride to form 2 molecules of acetic acid, according to the reaction shown below.
