| 20110152575 | Processes for Epimerizing Cyclohexenyl Ketones with Subsequent Aldol Condensation to Produce Fragrance Compounds - The present disclosure describes processes for the epimerization of a cyclohexene comprising the steps of providing to a reactor a first isomer of a 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone compound according to Formula I | 06-23-2011 |
| 20120184780 | PROCESS FOR THE PREPARATION OF ISOHUMULONE COMPOSITIONS - A process for preparing isohumulone compositions, which process provides an improvement over the extant art, and yields an isohumulone preparation derived from a hop extract of high yield and purity, which has excellent physical stability, and is essentially free from undesirable lupulones, fatty acids, hop oils and degradation compounds. | 07-19-2012 |
| 20130060066 | METHOD FOR ISOMERISATION OF HOP ALPHA-ACIDS USING HETEROGENEOUS ALKALINE EARTH METAL BASED CATALYSTS - The invention relates to a process for the production of iso-alpha-acids starting from hop alpha-acids in which an hop alpha-acid containing feed is contacted with a heterogeneous alkaline earth metal based catalyst, that essentially does not dissolve in the alpha-acid containing feed or in the iso-alpha-acid product phase, either in solvent-free conditions or in the presence of water, carbon dioxide, or an organic solvent or a mixture thereof. The resulting mixture is subjected to a temperature of at least 293 K, preferably under an inert atmosphere, for a time sufficient to effect high conversion of the alpha-acid reactant into the iso-alpha-acid product. The molar ratio of alpha-acid to earth alkaline metal (Mg, Ca, Sr, Ba) varies preferably between 0.2 and 20. After the isomerisation process, the heterogeneous alkaline earth metal based catalyst can be quantitatively separated from the iso-alpha-acid product phase by liquid-solid separation techniques. | 03-07-2013 |
| 20140249331 | PROCESS FOR PREPARING KETONES FROM EPOXIDES - A process for preparing a ketone by conversion of a compound E which contains an epoxy group to the ketone in the presence of a mixture comprising at least one noble metal and at least one metal oxide as a catalyst system, wherein the metal oxide in the catalyst system is at least one of titanium dioxide and zirconium dioxide, and the process is conducted at 0 to 0.9 bar of hydrogen. | 09-04-2014 |
| 20160060200 | PROCESS FOR THE ISOMERISATION OF AN EXO DOUBLE BOND - The present invention concerns a process for the isomerisation of an exo double bond toward an endo double bond being performed in the presence of a catalyst system comprising palladium (Pd) or platinum (Pt) and molecular hydrogen or a hydrogen source. | 03-03-2016 |
