20090247777 | FULLERENE DERIVATIVES - The present invention provides a fullerene derivative represented by the following formula (1): | 10-01-2009 |
20090318727 | PROCESS FOR THE PREPARATION OF RING COMPOUNDS - In a process for the preparation of ring compounds via a combinatorial synthesis, the reaction procedure is based on a Suzuki coupling, subsequent halo-demetallation and finally a further Suzuki coupling. The Suzuki couplings are each carried out with a boronic acid or a boronic acid ester. The reaction procedure uses provides novel ring compounds and uses novel synthesis units used for this purpose. The novel ring compounds are suitable for use as constituents in liquid-crystalline mixtures. | 12-24-2009 |
20110028750 | PROCESS FOR THE PREPARATION OF BETA-SANTALOL AND DERIVATIVES THEREOF - The present invention concerns a process for the preparation of a compound of formula (I) wherein R represents a Me or Et group, as well said compound in the form of any one of its stereoisomers or mixture thereof. The invention concerns also the use of compound (I) for the synthesis of β-santalol or of derivatives thereof. | 02-03-2011 |

20150119596 | METHOD FOR REFINING TRIMETHYLSILANE - Disclosed is a method for refining trimethylsilane, including the steps of (1) preparing an activated carbon loaded with at least copper (II) oxide and zinc oxide; (2) adsorbing a trimethylsilane onto the activated carbon; and (3) bringing a trimethylsilane containing silane, methylsilane or dimethylsilane as an impurity into contact with the activated carbon finished with the step (2) to remove the impurity from the trimethylsilane by adsorbing the impurity. According to this method, heat generation of the activated carbon is suppressed and impurities such as dimethylsilane, etc. can be removed efficiently. | 04-30-2015 |
