The invention relates to a method for separating an aromatic aldehyde from a mixture that also contains tar. The method of the invention for separating and recovering an aromatic aldehyde from a mixture containing an aromatic aldehyde, light and heavy impurities, and tar is characterised in that the method comprises feeding the liquid flow containing said mixture into an evaporator, vaporising said mixture in order to separate, on the one hand, a gaseous flow containing the aromatic aldehyde, the light impurities, the heavy impurities that can be vaporised at the selected evaporation temperature and pressure and, on the other hand, a liquid flow essentially containing the tar, and in that the aromatic aldehyde is recovered from the separated gaseous flow.
La présente invention a pour objet un procédé de séparation d'un aldéhyde aromatique à partir d'un mélange comprenant en outre des goudrons. Le procédé de l'invention de séparation et de récupération d'un aldéhyde aromatique à partir d'un mélange comprenant un aldéhyde aromatique, des impuretés légères et lourdes, des goudrons est caractérisé par le fait que l'on introduit le flux liquide comprenant ledit mélange dans un évaporateur, que l'on vaporise ledit mélange de telle sorte que l'on sépare d'une part un flux gazeux comprenant l'aldéhyde aromatique, les impuretés légères, les impuretés lourdes vaporisables à la température d'évaporation et de pression choisies et d'autre part un flux liquide comprenant essentiellement les goudrons et que l'on récupère l'aldéhyde aromatique à partir du flux gazeux séparé.
