Another embodiment provides for the manufacture of 1,1,1,3,3-pentafluoropropane which comprises adding hydrogen fluoride to 1,1,1,3-tetrafluoropropene in the presence of an amine hydrofluoride complex and a metal catalyst. | 03-05-2009 |
| 20090062577 | Process for the manufacture of 1,1,1,3,3-pentafluoropropane - A process for the manufacture of 1,1,1,3,3-pentafluoropropane, which comprises reacting 1,1,1,3,3,3-hexafluoropropane with a source of hydrogen. | 03-05-2009 |
| 20100181186 | Process for obtaining a purified hydrofluoroalkane - The invention consequently relates, in one aspect, to a process for obtaining a hydrofluoroalkane comprising at least two carbon atoms, which is purified of unsaturated organic impurities, according to which the hydrofluoroalkane containing organic impurities including (chloro)fluoro olefins is subjected to at least one purification treatment with bromine or BrCl, preferably in the presence of, an initiator. The process is suitable, for example, to purify 1,1,1,2-tetrafluoroethane. A further aspect concerns the application of LEDs or OLEDs to support chemical reactions of the gas-gas, liquid-liquid or gas-liquid type, and a respective reactor. | 07-22-2010 |
| 20100191024 | Preparation of halogen and hydrogen containing alkenes over metal fluoride catalysts - Halogenated alkenes, especially fluorinated alkenes can be prepared from halogenated and fluorinated alkanes, respectively, by dehydrohalogenation or dehydrofluorination in the presence of a high-surface metal fluoride or oxifluoride. Preferably, trifluoroethylene, pentafluoropropene, tetrafluorobutenes or trifluorobutadiene are prepared. Aluminium fluoride is highly suitable. The metal fluoride or oxifluoride can be applied supported on a carrier. | 07-29-2010 |
| 20110206598 | Preparation of hydrogen fluoride from fluorspar or calcium fluoride containing waste material - A process for the preparation of HF and anhydrite from reaction of calcium fluoride in the form of fines and sulfuric acid. The content of sulfuric acid is kept in a range where no agglomeration occurs. In such process, dust originating from natural fluorspar can be reacted, as well as synthetic calcium fluoride, e.g., from calcium fluoride and optionally calcium carbonate containing solids from treating a waste gas or waste water with basic calcium compounds to remove contained HF. | 08-25-2011 |
| 20110215273 | Hydrofluoroolefins, manufacture of hydrofluoroolefins and methods of using hydrofluoroolefins - A hydrofluoroolefin and hydrofluoroolefin isomers and a process for manufacture them comprising eliminating HF from a fluorinated precursor compound are described. The fluorinated precursor compound may be provided by fluorinating a chlorinated precursor. The fluorinated precursor compound may be a fluorinated alkane. The hydroolefines are suitable as blowing agents, heat transfer fluids, or drying agents or degreasing solvents. | 09-08-2011 |
| 20110224464 | Process for the preparation of chlorofluoroalkenes - One or more hydrochlorofluoroalkenes can be produced by dehydrofluorination of a hydrochlorofluoroalkane over a X-ray amorphous high surface metal fluoride or a X-ray amorphous or weakly crystalline metal oxide fluoride wherein the metal is selected from the 2 | 09-15-2011 |

| 20110120155 | Room Air Conditioner And/Or Heater - A room air conditioner and/or heat pump is shown having a compressor, indoor coil, accumulator, expansion device and reversing valve for changing between a cooling cycle and a heating cycle. Intake louvers direct return air over the entire indoor coil for maximum heat transfer. Discharge louvers are curved upward to prevent short cycling while still being totally adjustable, up and down, right and left. Adjustment posts are anchored to a clip and are adjustable for right or left discharge of air and up or down discharge. Single handles control both the right or left discharge through a rear set of louvers and up or down discharge through a front set of louvers. A no circulation area prevents short cycling and curved edges prevent turbulence in air flow through louvers. | 05-26-2011 |
| 20110120167 | Room Air Conditioner And/Or Heat Pump - A room air conditioner and/or heat pump is shown with a main control and a user interface. The user interface is mounted on a user interface mount attached to the front of a main unit, but behind the bezel. The user interface mount is used to (a) insert or remove the main unit, (b) secure and protect wiring cables, (c) mount the user interface thereon, (d) direct a filter into position, (e) provide a slot for a fresh air slide, and (f) direct a bezel into position. A main control housing allows access there through to a main control circuit board, but prevents moisture from dripping on the main control circuit board. A dual filter element is located behind a double hinged door. Channels and flanges direct and secure the bezel into position. | 05-26-2011 |
| 20110125328 | Control System for a Room Air Conditioner and/or Heat Pump - A universal control system is provided for a room air conditioner or heat pump that has a number of sensor inputs. An electronic control system with a microcontroller and microcomputer are used to provide a large number of operations that can be performed by (1) manufacturer, (2) end users and (3) maintenance personnel. The manufacturer can load different versions of a software program to match the unit. The end user can program in a large number of different conditions or schedules the end user finds desirable, plus the end user is advised of maintenance requirements or faults. The maintenance personnel may perform diagnostics, determine fault history, upload improved or replacement software, as well as the numerous maintenance functions normally performed by maintenance personnel. | 05-26-2011 |
