  • Patent number: 9334215
    Abstract: The invention relates to a process for separating acrolein from the process gas of a heterogeneously catalyzed oxidation of propene by means of atmospheric oxygen, wherein high boilers (including acrylic acid) are firstly separated off from the process gas by means of quenching and technical-grade acrolein having small proportions of low boilers is then obtained by means of absorption and subsequent distillation. Small amounts of a solvent by means of which, in particular, oligomers formed are separated off and the tendency for foam to be formed in the apparatuses or columns is reduced is added in the columns and heat exchangers in the work-up process. The solvent is, according to the invention, separated off and recycled in the form of an organic phase in-situ within the existing process.

  • Patent number: 7717774
    Abstract: An arrangement for the sterile, aseptic production and/or filling of pharmaceutical products contains a housing which, with the exception of an inlet and an outlet with a clearly defined cross-section, is closed in an airtight manner. Through the air inlet air is forced via a filter into the interior of the housing. The air passes out of the housing through the air outlet or channels. The size of the cross-section of the air outlet and the performance of the ventilating device are matched in such a way that within the interior of the housing there is a laminar unidirectional or combined airflow and a constant overpressure with respect to the pressure outside the housing.

Through the air inlet air is forced via a filter into the interior of the housing. The air passes out of the housing through the air outlet or channels. The size of the cross-section of the air outlet and the performance of the ventilating device are matched in such a way that within the interior of the housing there is a laminar unidirectional or combined airflow and a constant overpressure with respect to the pressure outside the housing. This overpressure is kept at a constant value by a regulating device. With respect to the cleanness and the protection of the product obtained, the arrangement is comparable with an isolator, but can be manufactured, installed, validated and operated much less expensively.

  • Patent number: 5977011
    Abstract: A catalyst for the synthesis of methyl mercaptan from hydrogen sulfide and methanol as well as a process for preparation of the catalyst. The catalyst is an active aluminum oxide onto which 5 to 25% by weight potassium tungstate is deposited as an activator. A two-stage impregnation with intermediate drying produces a catalyst which exhibits distinctly better selectivity for formation of methyl mercaptan than catalysts obtained by single-stage impregnation.

  • Patent number: 5886230
    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.

  • Patent number: 5866721
    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.

  • Patent number: 5852219
    Abstract: A catalyst for the synthesis of methyl mercaptan from hydrogen sulfide and methanol, as well as a process for preparing the catalyst. The catalyst contains active aluminum oxide on which 15% to 40% by weight cesium tungstate is deposited as the activator. The activator, cesium tungstate, gives an unexpected increase in activity and selectivity as compared with potassium tungstate, which is used exclusively at the present state of the art.

  • Patent number: 5688973
    Abstract: Process for the production of 2-vinyl-1,3-dioxolane reacting acrolein with ethylene glycol in the presence of a solid, acidic catalyst and recovery of the reaction mixture. Selectivity may be increased in comparison with known prior art processes by performing the reaction in the presence of a solid acidic catalyst at a temperature of below 50.degree. C.; the reaction mixture, from which the catalyst has been removed, is treated by extraction using an organic solvent which substantially does not dissolve ethylene glycol and has a boiling point of above 130.degree. C.; the two phases obtained on extraction are treated for recovery by distillation and recovered educts and the organic solvent are recycled.

  • Patent number: 5216179
    Abstract: Mixed cyclic acrolein glycerol acetals can be obtained by reacting acrolein with glycerol in the presence of a solid acidic catalyst and by a distillation workup in a higher space-time yield and in very high selectivity in comparison to the state of the art if the reaction is carried out in the presence of the reaction mixture as solvent, which mixture consists essentially of acrolein, glycerol, cyclic acrolein glycerol acetals and water, and in the absence of heterogeneous solvents and, to the extent necessary, the reaction mixture freed of catalyst is compounded prior to being worked up by distillation with such an amount of pH-increasing substance that it exhibits a pH in a range of 4.5 to 7 in tenfold dilution with water. The reaction preferably takes place at 10.degree. to 30.degree. C. using strongly acidic organic or inorganic ion exchangers.
