Patent number: 7465410Abstract: A reactor for an in-situ production of a chemical product in high yield are presented. The reactor, which may be placed in a main solvent, includes a core and a reactor wall around the core. The reactor wall allows controlled permeation of the main solvent to the core. The core contains a reactant that reacts to produce a target product upon being contacted by a main solvent. The target product leaves the reactor at a controlled rate. Because the amount of the main solvent that permeates into the reactor is controlled, a high concentration of the reactant is maintained inside the reactor, resulting in a higher yield of the desired chemical product than if the reactants were directly added to the body of main solvent.Type: GrantFiled: February 18, 2005Date of Patent: December 16, 2008Assignee: Truox, Inc.Inventors: Perry L.

Publication number: 20080251759Abstract: The invention relates to a method for producing ionic liquids and ionic solids which takes recourse to a novel, especially modular production process. According to the inventive method, those salts from an ionic carbonate, hydrocarbonate or monoalkyl or monoaryl carbonate precursor (cationic synthesis module) are produced that comprise the desired quaternary ammonium, phosphonium, sulfonium or the analogous quaternary heteroaromatic cation. This precursor can be produced and stored efficiently and with a high degree of purity. The actual process for producing the desired ionic compound, which comprises the introduction of the desired anion, is, unlike generic production processes known so far, flexible, fast and generally applicable. In a preferred embodiment, the carbonate, hydrocarbonate or monoalkyl or monoaryl carbonate anion is completely removed in the form of a gaseous carbon dioxide by reaction with any Brønsted acid (anionic synthesis module) and is replaced by the anion that is conjugated to acid.Type: ApplicationFiled: August 19, 2004Publication date: October 16, 2008Inventors: Roland Kalb, Wolfgang Staber, Michael Schelch, Michael Kotschan, Robert Hermann, Wolfgang Wesner
