Abstract

L'invention concerne un procédé de fabrication de trioxane et d'au moins un comonomère pour la fabrication de (co)polymères à base de trioxane, selon lequel dans une première étape du formaldéhyde et au moins un réactif comonomère sont transformés en solution aqueuse en du trioxane et en un comonomère, un mélange réactionnel A1 contenant du trioxane, un comonomère, du formaldéhyde, de l'eau et éventuellement un réactif comonomère étant obtenu. Dans une deuxième étape, le mélange réactionnel A1 est distillé lors d'une première étape de distillation à une première pression, un flux B1 enrichi en trioxane et en comonomère et un flux B2 contenant essentiellement de l'eau, du formaldéhyde et l'éventuel réactif monomère étant obtenus. Dans une troisième étape, le flux B1 est distillé lors d'une seconde étape de distillation à une pression supérieure à la pression utilisée lors de la première étape de distillation, un flux C1 contenant du trioxane, un comonomère et de l'eau et un flux C2 constituant le produit final contenant essentiellement un comonomère et du trioxane étant obtenus.
