| 20120071676 | SYNTHESIS OF TERMINAL ALKENES FROM INTERNAL ALKENES AND ETHYLENE VIA OLEFIN METATHESIS - This invention relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by a selected olefin metathesis catalyst. In one embodiment of the invention, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting an olefinic substrate comprised of at least one internal olefin with ethylene, in the presence of a metathesis catalyst, wherein the catalyst is present in an amount that is less than about 1000 ppm relative to the olefinic substrate, and wherein the metathesis catalyst has the structure of formula (II) | 03-22-2012 |
| 20110237850 | METHODS OF PRODUCING JET FUEL FROM NATURAL OIL FEEDSTOCKS THROUGH METATHESIS REACTIONS - Methods are provided for producing a jet fuel composition from a feedstock comprising a natural oil. The methods comprise reacting the feedstock with a low-weight olefin in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product. The methods further comprise hydrogenating the metathesized product under conditions sufficient to form a jet fuel composition. | 09-29-2011 |
| 20110160472 | CHEMICAL METHODS FOR TREATING A METATHESIS FEEDSTOCK - Various methods are provided for metathesizing a feedstock. In one aspect, a method includes providing a feedstock comprising a natural oil, chemically treating the feedstock under conditions sufficient to diminish catalyst poisons in the feedstock, and, following the treating, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock. | 06-30-2011 |
| 20100132250 | PRILLED WAXES COMPRISING SMALL PARTICLES AND SMOOTH-SIDED COMPRESSION CANDLES MADE THEREFROM - A candle and process for making it are disclosed. The candle comprises prilled wax particles, comprising hydrogenated natural oil and wherein at least 75% of the prilled wax particles are less than 800 μm in diameter. The candle includes a compressed core and a thermally fused outer layer. | 06-03-2010 |
| 20090264672 | METHODS OF MAKING ORGANIC COMPOUNDS BY METATHESIS - Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like. | 10-22-2009 |
| 20090220443 | COMPOSITIONS COMPRISING METATHESIZED UNSATURATED POLYOL ESTERS - Disclosed are petrolatum-like compositions that comprise metathesized unsaturated polyol esters. Also disclosed are emulsions comprising metathesized unsaturated polyol esters. The petrolatum-like compositions may be used as substitutes for petroleum-based petrolatum. The emulsions may be water-in-oil or oil-in-water emulsions and may be suitable for a variety of end uses. | 09-03-2009 |
| 20090217568 | Candle and candle wax containing metathesis and metathesis-like products - A wax comprises a metathesis product and/or a product that resembles, at least in part, a product which may be formed from a metathesis reaction. The wax may be used to form articles, for example, candles (container candles, votive candles, and/or a pillar candles), crayons, fire logs, or tarts. The wax commonly includes other components in addition to the metathesis product. | 09-03-2009 |
| 20090126602 | COLORANT COMPOSITIONS COMPRISING METATHESIZED UNSATURATED POLYOL ESTERS - Disclosed are improved colorant compositions that are suitable for encapsulation in an impact-rupturable casing that is adapted for intact projectile motion and rupture upon contact with a target surface. In many embodiments, the colorant compositions comprise (a) a carrier comprising: (i) a metathesized unsaturated polyol ester; and (ii) a polyol ester; and (b) a colorant. The colorant compositions are useful in paint balls for use in conjunction with projectile devices, such as paint ball markers. | 05-21-2009 |
| 20090119977 | TRIACYGLYCEROL BASED CANDLE WAX - A triacylglycerol-based wax includes a triacylglycerol component and a polyol fatty acid partial ester component. The triacylglycerol-based wax may have a melting point of about 54° C. to 63° C., may have an Iodine Value of about 20 to 40, and may have a fatty acid profile including about 50 to 70 wt. % saturated fatty acids. The wax may be suitable for use as a candle. | 05-14-2009 |
