Abstract
L'invention décrit un procédé pour extraire ou recueillir par séparation une dialkylarylcétone d'un mélange huileux contenant une grande proportion d'un 1,1-diaryl-2-nitroéthylène comme impureté. On chauffe le mélange huileux jusqu'à une température d'au moins 140 degrés C environ, puis l'on recueille la dialkylarylcétone solide que l'on sépare d'une solution du 1,1-diaryl-2-nitroéthylène dans un solvant. Les produits obtenus peuvent servir dans la fabrication des parfums et savons parfumés, ainsi que d'intermédiaires de synthèse pour la production d'insecticides ou de produits pharmaceutiques.
