Abstract: A battery housing for accommodating one or more battery modules in its housing interior to form a traction battery for a motor vehicle, includes a housing section for partially delimiting the housing interior, the housing section having an exhaust duct integrated therein for discharging media which emerge from a battery module in the event of a defect thereof to the surroundings, and the exhaust duct having an inlet region through which the media enter the exhaust duct from the housing interior, and a first deflection region which is designed and configured to change the transport direction of the media.

Abstract: The present invention relates to a lid for a battery module, in particular in an electric vehicle, comprising a cover section for pole-side attachment of the lid to the battery module, and tabs which are provided at opposite ends of the cover section, are arranged inclined relative to the cover section and, in a state in which the lid is installed on the battery module, extend from the cover section in a direction pointing away from the battery module.

Abstract: In a process for separating liquid mixtures comprising formaldehyde, trioxane, alcohol, hemiformal formed from the formaldehyde and the alcohol, usual minor components and up to 5% by weight of water, the liquid mixture is distilled batchwise or continuously at reduced pressure, atmospheric pressure or superatmospheric pressure in suitable apparatuses which are to be connected to one another in an appropriate manner, and the trioxane is produced in very high purity. The other materials of value, formaldehyde and alcohol, present in the mixture can likewise optionally be separated off and recycled or used otherwise, while the minor components are ejected.

Abstract: The invention relates to a method for separating a gaseous mixture comprising formaldehyde and trioxane, wherein at least some of the formaldehyde and the trioxane are dissolved from the mixture in a alcohol-containing liquid and the trioxane is crystallized from the solution thus obtained and is separated.
