Abstract

L'invention concerne un procédé de production d'acide acrylique ou d'acide méthacrylique comportant les étapes suivantes: (a) production d'un produit réactionnel gazeux renfermant de l'acide acrylique ou méthacrylique et ayant essentiellement la composition d'un mélange réactionnel issu de l'oxydation catalytique en phase gazeuse d'alcanes C3-/C4-, d'alcènes, d'alcanols et/ou d'alcanals et/ou de précurseurs de ceux-ci conduisant à la formation de l'acide acrylique ou méthacrylique, (b) absorption du produit réactionnel avec un mélange solvant renfermant au moins un lactame dissous dans au moins un solvant organique polaire, et (c) distillation du mélange solvant chargé du produit réactionnel pour obtenir un acide acrylique brut ou un acide méthacrylique brut et le mélange solvant.
