Abstract

Acrylic or methacrylic acids are prepared by heating the ammonium salt of the acid in solution or suspension in an inert liquid organic medium with a boiling point or minimum boiling point under the reaction conditions not lower than 80 DEG C. Benzene, toluene, ethylbenzene or a xylene are mentioned as solvents, and the condensable distillate is refluxed during the heating. Ammonia is evolved and the free acid recovered by extraction or distillation.
