    Abstract: Proposed is a method for purifying a recycle stream (1) from a system for producing polyarylene ether sulfones by the polycondensation of aromatic bis-halogen compounds and aromatic bisphenols or salts thereof in the presence of at least one alkali metal- or ammonium carbonate or -hydrogen carbonate in an N-alkyl-2-pyrrolidone as a solvent, containing 60 to 90% by weight water, 10 to 40% by weight N-alkyl-2-pyrrolidone and, as a specification-detrimental impurity, up to 5000 ppm by weight of the alkyl succinimide corresponding to the N-alkyl-2-pyrrolidone and, in addition, up to 1000 ppm by weight additional high boilers relative to N-alkyl-2-pyrrolidone, in particular inorganic salts, each relative to the total weight of the recycle stream (1), the sum of the components being 100% by weight, to obtain a purified N-alkyl-2-pyrrolidone stream (2) that can be fed back into the system for producing polyarylene ether sulfones by purification by distillation in a purification column (K). Said method is characterized in that a prepurification step by evaporation in one or more evaporator stages is provided upstream of the purification by distillation in order to reduce the content of inorganic salts, one or more vapor streams (3, 4, 5) being obtained which are fed to the purification column (K) as feed streams. The bottom stream is discharged from the last evaporator stage and the bottom stream from the purification column (K) is entirely recycled into the last evaporator stage. The vapor stream (5) from the last evaporator stage is partially or entirely fed to an additional column (ZK) from which a top stream is removed, which is is fed to the purification column (K), and a bottom stream, which is discharged.

    Abstract: Disclosed is a method for producing polyoxymethylene homopolymers or copolymers (7) by homopolymerizing or copolymerizing trioxane, starting from methanol (1) that is oxidized in a first reactor of a first production system (A) such that an aqueous formaldehyde-containing stream (2) is obtained that is fed to a second production system (B) in which pure trioxane (6) is obtained. In said method, low-boiling fractions (5) are separated by distillation, and the pure trioxane (6) is fed to a third production system (C) in which the pure trioxane (6) is homopolymerized or copolymerized to obtain polyoxymethylene homopolymers or copolymers (7). The disclosed method is characterized in that the stream of low-boiling fractions (5) is recycled from the column (K 2) separating low-boiling fractions into the inlet of the first reactor in the first production system (A).

    Abstract: Se describe un método para producir homopolímeros o copolímeros de polioximetileno (7) por homopolimerización o copolimerización de trioxano, iniciando a partir de metanol (1) que se oxida en un primer reactor de un primer sistema de producción (A) de modo que se obtenga una corriente acuosa que contenga formaldehido (2) el cual es alimentado a un segundo sistema de producción (B) en el cual se obtiene el trioxano puro (6). En ese método, las fracciones de baja ebullición (5) se separan por destilación, y el trioxano puro (6) se alimenta a un tercer sistema de producción (C) en el cual se homopolimeriza o copolimeriza el trioxano puro (6) para obtener homopolímeros o copolímeros de polioximetileno (7). El método descrito se caracteriza en que la corriente de fracciones de baja ebullición (5) se recircula a partir de la columna (K2) separando las fracciones de baja ebullición hacia la entrada del primer reactor en el primer sistema de producción (A).
