| 20120116131 | CATALYST AND PROCESS USING THE CATALYST - A new chromium-containing fluorination catalyst is described. The catalyst comprises an amount of zinc that promotes activity. The zinc is contained in aggregates which have a size across their largest dimension of up to 1 micron. The aggregates are distributed throughout at least the surface region of the catalyst and greater than 40 weight % of the aggregates contain a concentration of zinc that is within ±1 weight % of the modal concentration of zinc in those aggregates. | 05-10-2012 |
| 20110260095 | Heat Transfer Compositions - The invention provides a heat transfer composition comprising R-1243zf, R-32 (difluoromethane) and R-161 (fluoroethane). | 10-27-2011 |
| 20110258147 | Heat Transfer Compositions - The invention provides a heat transfer composition comprising: (ii) R-1243zf; (iii) a second component selected from R-32 (difluoromethane), R-744 (CO)2, R-41 (fluoromethane), R-1270 (propene), R-290 (propane), R-161 (fluoroethane) and mixtures thereof; and (iv) a third component selected from R-134a (1,1,1,2-tetrafluoroethane), R-125 (pentafluoroethane), R-1234yf (2,3,3,3-tetrafluoroprop-1-ene) and mixtures thereof. | 10-20-2011 |
| 20110258146 | Heat Transfer Compositions - The invention provides a heat transfer composition comprising a minimum of about 80% by weight of R-1243zf and a maximum of 20% by weight of R-32, based on the total weight of the composition. | 10-20-2011 |
