| 20120126187 | HEAT TRANSFER COMPOSITIONS - The invention provides a heat transfer composition comprising: (i) 1,3,3,3-tetrafluoroprop-1-ene (R1234ze, CF | 05-24-2012 |
| 20120071699 | Process For Preparing 3,3,3-Trifluoropropene - The invention provides a process for preparing 3,3,3-trifluoropropene (1243zf), the process comprising contacting a compound of formula CX | 03-22-2012 |
| 20110191268 | HEAT TRANSFER COMPOSITIONS - The invention provides a heat transfer composition comprising R-1234ze(E), R-32 and 1,1,1,2-tetrafluoroethane (R-134a). | 08-04-2011 |
| 20110184890 | HEAT TRANSFER COMPOSITIONS - A heat transfer composition comprising trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)), difluoromethane (R-32) and 1,1-difluoroethane (R-152a). | 07-28-2011 |
| 20110173997 | HEAT TRANSFER COMPOSITIONS - Heat transfer compositions are usable in their own right or are suitable as a replacement for existing refrigeration usages. The compositions possess a reduced Greenhouse Warming Potential, yet have a capacity and energy efficiency (which may be conveniently expressed as the “Coefficient of Performance”) ideally within 20% of the values of those attained using R-134a, and preferably within 10% or less (e.g. about 5%) of these values. | 07-21-2011 |
| 20110162410 | HEAT TRANSFER COMPOSITIONS - A heat transfer composition comprising trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)), carbon dioxide (R-744) and a third component selected from difluoromethane (R-32), 1,1-difluoroethane (R-152a), fluoroethane (R-161), 1,1,1,2-tetrafluoroethane (R-134a), propylene, propane and mixtures thereof. | 07-07-2011 |
| 20110112338 | Process for the Preparation of 2,3,33-Trifluoropropene - The invention provides a process for the preparation of 1234yf comprising (a) contacting 1,1,2,3,3,3-hexafluoropropene (1216) with hydrogen in the presence of a hydrogenation catalyst to produce 1,1,2,3,3,3-hexafluoropropane (236ea); (b) dehydrofluorinating 236ea to produce 1,2,3,3,3-pentafluoropropene (1225ye); (c) contacting 1225ye with hydrogen in the presence of a hydrogenation catalyst to produce 1,2,3,3,3-pentafluoropropane (245eb); and (d) dehydrofluorinating (245eb) to produce (1234yf). | 05-12-2011 |
