Patent number: 6469203Abstract: 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 The resulting vapors are withdrawn and condensed, where the hot heat-transfer medium is continuously supplied at one end of the reactor, and cooled heat-transfer medium is discharged at the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.Type: GrantFiled: June 21, 2001Date of Patent: October 22, 2002Assignees: Metallgesellschaft Aktiengesellschaft, Rohm GmbH Chemische FabrikInventors: Hans-Jürgen Weiss, Jörg Schmalfeld, Udo Zentner, Tobias Groschang, Udo Gropp, Werner Fuss, Ralf Goedecke, Egbert Schöla

Patent number: 6221294Abstract: 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.Type: GrantFiled: June 15, 2000Date of Patent: April 24, 2001Assignee: Degussa AktiengesellschaftInventors: Ralf Goedecke, Klaus Hentschel, Rolf-Dieter Möller, Knut Ehrhardt, Manfred Schmidt, Michael Kissner

Patent number: 6136242Abstract: 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.Type: GrantFiled: April 8, 1999Date of Patent: October 24, 2000Assignee: Degussa-Huls AGInventors: Knut Ehrhardt, Ralf Goedecke, Rolf Moller, Juan Garcia

Patent number: 5886230Abstract: 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.Type: GrantFiled: June 30, 1997Date of Patent: March 23, 1999Assignee: Degussa AktiengesellschaftInventors: Willi Hofen, Wolfgang Boeck, Stephan Rautenberg, Joerg Sauer, Dietrich Arntz, Ralf Goedecke, Wolfgang Taugner, Raymund Sonnenschein

Patent number: 5866721Abstract: 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.Type: GrantFiled: June 30, 1997Date of Patent: February 2, 1999Assignee: Degussa AktiengesellschaftInventors: Willi Hofen, Wolfgang Boeck, Stephan Rautenberg, Joerg Sauer, Dietrich Arntz, Ralf Goedecke, Wolfgang Taugner, Raymund Sonnenschein
