Process for preparing polyoxymethylene homopolymers or copolymers by homopolymerization or copolymerization of trioxane, starting from methanol |
| abstract |
A process for preparing polyoxymethylene homopolymers or copolymers ( 7 ) by homopolymerization or copolymerization of trioxane, starting from methanol ( 1 ), in whichn methanol ( 1 ) is oxidized in a first reactor in a first production plant (A) to give an aqueous formaldehyde-comprising stream ( 2 ) which is fed to a second production plant (B) in which pure trioxane ( 6 ) is obtained and removal of low boilers ( 5 ) by distillation is carried out and the pure trioxane ( 6 ) is fed to a third production plant (C) in which it is homopolymerized or copolymerized to form polyoxymethylene homopolymers or copolymers ( 7 ), wherein the low boiler stream ( 5 ) from the low boiler removal column (K 2 ) is recycled to the feed stream into the first reactor in the first production plant (A), is proposed. |
