| 20080293959 | COMPOSITIONS USEFUL AS CHROMATOGRAPHY STATIONARY PHASES - The current invention provides compositions, which are useful as stationary phases for a variety of chromatographic applications, such as high performance liquid chromatography (HPLC). The compositions include a substrate (e.g., silica gel), covalently bound to a compound, which includes both a hydrophobic moiety and a hydrophilic moiety, which is preferably a 1,2-diol moiety. The hydrophobic moiety is sufficiently hydrophobic for the compositions to exhibit reversed phase characteristics and typically incorporates at least 5 carbon atoms in sequence. Based on having both hydrophilic and hydrophobic functionalities, the new stationary phases exhibit unique chromatographic properties. For example, these media can be used in either hydrophilic (HILIC) mode, in which the mobile phase includes a high percentage of an organic solvent, or in reversed phase mode, in which the mobile phase contains a higher percentage of an aqueous solvent. The current invention also provides methods of making and using the compounds and compositions of the invention. | 11-27-2008 |

| 20100197949 | PROCESS FOR PREPARING ORGANOSILICON COMPOUNDS CONTAINING ORGANYLOXY GROUPS - Organosilicon compounds bearing silicon-bonded organyloxy groups are prepared by mixing and reacting silanol-functional organosilicon compounds with organosilicon compounds containing at least two organyloxy groups in a mixer with an energy input of at least 0.2 kW/Kg of mixture. At this level of energy input, reaction to form the organyloxy-functional product is rapid, and can be achieved without supplying external heat, and also without catalysts, if desired. | 08-05-2010 |
| 20110118495 | CARDANOL BASED DIMERS AND USES THEREFOR - Cardanol based dimers are provided. The cardanol dimers are formed by hydrosylylation with silanes. Cardanol based dimers may be further reacted to form epoxy curing agents and epoxies which can be used as anti-fouling coatings on ship hulls and marine structures. The cardanol dimers may also be used to produce friction particles or phenolic resins. Methods of synthesizing the cardanol based dimers, the epoxy curing agents and the epoxies are also provided. | 05-19-2011 |

| 20090112013 | PREPARATION OF SI-SI BOND-BEARING COMPOUNDS - Si—Si bond-bearing compounds are effectively prepared by irradiating with radiation or heating Si—H group-bearing silicon compounds in organic solvents in the presence of iron complex catalysts. The Si—Si bond-bearing compounds are useful as a base material in photoresist compositions, ceramic precursor compositions, and conductive compositions. | 04-30-2009 |
| 20120330045 | PROCESS FOR CONVERSION OF DISILANES - Highly alkyl-substituted disilanes generally considered as uncleavable, obtained as part of the residue of alkylchlorosilane synthesis, are converted into cleavable disilanes having fewer alkyl groups by reaction with hydrogen halide in the presence of an alumina catalyst. The resulting disilanes can be cleaved into commercially valuable monosilanes by conventional processes. | 12-27-2012 |
