Patent number: 7749483Abstract: Disclosed is a processes for the production of relatively high purity alkaline earth metal oxides, such as SrO, from relatively low purity forms of carbonated or other oxygenated forms of such metals, such as strontium carbonate. The relatively low purity material is exposed to conditions under which at least a portion of the metal contained therein is converted to a salt that is more readily solvated in a provided solvent than the starting material, while at the same time not substantially increasing the solubility of at least one or more of the impurities in such selected solvent. This step is then preferably followed by removal of solid or otherwise un-dissolved impurities from the solution. After the removal step, the solution is preferably exposed to conditions effective to form a relatively insoluble salt of the alkaline earth metal, such as a strontium salt. The insoluble salt is also preferably one that can be readily and effectively converted to the desired alkaline earth metal oxide, preferably SrO.Type: GrantFiled: December 15, 2006Date of Patent: July 6, 2010Assignee: Honeywell International Inc.Inventors: Thomas Scholten, Michael Fooken, Jessica Mauer, Andreas Kanschik-Conradsen, Michael Hau

Patent number: 7208610Abstract: An improved process and catalyst system for the isomerization of halothiophenes. More particularly, an improved process for the isomerization of 2-halothiopehenes to 3-halothiophenes by reacting a 2-halothiophene with a catalyst and in the presence of a base. The addition of a base additive to the acidic zeolite catalyst allows the desired isomerization reaction to take place while suppressing side-reactions that result in the decomposition of thiophene rings. The catalyst lifetime is thus increased and the amount of catalyst needed for the reaction is reduced, lowering cost.Type: GrantFiled: January 12, 2005Date of Patent: April 24, 2007Assignee: Honeywell International Inc.Inventors: Christian Werner, Andreas Kanschik-Conradsen, Bernd Kellermeier, Hans-Jürgen Schmidt

Publication number: 20060129002Abstract: The invention provides a process for the production of 4-(C2-C16)alkylresorcinol. 4-(C2-C16)alkylresorcinol is produced by reacting resorcinol with a (C2-C16)alkyloic acid in the presence of a zinc chloride catalyst to produce an intermediate comprising a 4-(C2-C16)acylresorcinol and zinc ions. Then the intermediate is adjusted such that the zinc ion content is from about 0.1 to about 150 parts per million based on the weight of the intermediate to form an adjusted intermediate. Then the produced 4-(C2-C16)acylresorcinol is hydrogenated in the presence of the zinc ions and a base metal hydrogenation catalyst to produce a crude product comprising 4-(C2-C16)alkylresorcinol, which may thereafter be isolated.Type: ApplicationFiled: December 15, 2004Publication date: June 15, 2006Inventors: Suzanne Wassmann-Wilken, Hans-Jurgen Schmidt, Jorg Wilken, Andreas Kanschik-Conradsen
