Abstract: The invention relates to a method for obtaining a dialkyl carbonate and an alkylene glycol from a material flow containing dialkyl carbonate alkylene carbonate alkylene glycol and alcohol said method having the following steps: (a) separating a material flow (5) containing dialkyl carbonate and alkylene glycol in the form of a heteroazeotrope from the material flow containing dialkyl carbonate alkylene carbonate alkylene glycol and alcohol in a distillative manner in a first distillation stage (1) and (b) separating the material flow (5) containing dialkyl carbonate and alkylene glycol in the form of a heteroazeotrope into a first raw product flow (27) which substantially contains dialkyl carbonate and a second raw product flow (29) which substantially contains alkylene glycol in a device for the purpose of a phase separation (25).

Abstract: The invention relates to moulded bodies having catalytic properties, obtained due to a method that comprises the following said steps: a) a moulded body is produced by means of a powder-based rapid- prototyping-method, b) said moulded body is optionally heat-treated, c) at least one catalytically active component is optionally applied to the moulded body, d) said moulded body is optionally subjected to another heat-treatment. The steps b, c) and/or d) can be performed several times. Said moulded bodies are used as reactor fittings in heterogeneously catalyzed chemical reactions.
