Abstract: The invention relates to a battery arrangement in a two-track vehicle, having a traction battery (5) with a battery housing (17) in which crash-sensitive battery cells (15) are arranged, and in which at least one crash cross-member (47) which runs in the transverse direction (y) of the vehicle is arranged, with which, in the event of a side crash, the applied impact force can be transmitted to the side of the vehicle at a distance from the crash, while bypassing the battery cells (15).

Abstract: The present invention concerns a process for separation of a monomer including at least one double bond, hereafter referred to as “monomer,” in particular (meth)acrylic acid, from a composition Z including this monomer and at least one impurity different to the monomer, including the steps of bringing into contact of the composition Z with an additive by forming a separation phase. The additive has a melting point of at most about 150° C. and a vapour pressure at a temperature of 20° C. of at most about 1 mbar. The monomer is then separated from the separation phase. A device for producing a monomer, the use of additives in the separation of a monomer from a monomer-comprising composition, the monomer obtainable by the process according to the invention, chemical products comprising the monomer as well as the use of the monomer in or for production of chemical products.

Abstract: The present invention is directed to an improved process for producing methionine in which the by-product methionyl-methionine is quickly converted to the product methionine by a hydrolysis reaction. The process is performed at high temperatures (200° C. to 280° C.) and short residence times (20 s to 200 s) and results in an improved yield of end product methionine.

Abstract: A process is disclosed for the preparation of anhydrous sodium sulfide by heating sodium sulfide having a water content of from 38 to 40% in a contact drier in vacuo, the temperature of the solid to be dried being increased from approximately 20° C. at the solid inlet to ≧180° C. at the solid outlet.

Abstract: The present invention relates to a process of recovering monomeric esters of substituted or unsubstituted acrylic acid from polymer material having corresponding structural units by depolymerization by means of a fine-grained heat-transfer medium which is maintained above the depolymerization temperature of the polymer material. In a reactor, the polymer material is brought in contact with hot, mechanically fluidized heat-transfer medium. The resulting vapors are withdrawn and condensed, where the hot heat-transfer medium is continuously supplied at one end of the reactor, and cooled heat-transfer medium is discharged at the other end.

Abstract: Cyanuric chloride moldings, especially tablets and flakes, have advantages over powders in ease of handling. The moldings are produced by droplet or strip application of molten cyanuric chloride on to a surface and dissipation of the latent heat of fusion by cooling the surface or contacting the melt applied as droplets or strips with a cooling gas.

Abstract: The invention relates to a process for the production of cyanuric chloride moldings, particularly in rod or flake form. Cyanuric chloride melt is cooled in a pressure cell equipped with a die capable of strand formation, wherein solidification takes place in the channel or channels of the die. The solidified cyanuric chloride is pressed out of the die in strand form at a temperature of 140.degree. C. or less, preferably 40 to 60.degree. C., and reduced in size as required. The process reduces the sublimation which is otherwise conventional during solidification and cooling.

Abstract: A process for continuous production of methyl mercaptan by catalytic reaction of methanol and hydrogen sulfide. Significant improvements in the pretreatment of the feed gas mixture and in utilization of the heat of reaction and the heat content of the product gas mixture. The energy required to vaporize the methanol is derived partly from utilization of the heat of compression of the hydrogen sulfide gas and from the heat content of the product gas leaving the reactor. The heat of reaction is utilized to heat the feed gas mixture to the reaction temperature, with the help of an external gas heater.

Abstract: A process for separating the product gas mixture from the catalytic synthesis of methyl mercaptan. Because of improved separation of the product gas mixture into its components, less hydrogen sulfide and methyl mercaptan are lost in discharging the inert gases than in the known process. The inert gases can be burned without after-treatment of the exhaust gas. Likewise, the process water that is discharged is less contaminated with polysulfides.
