20150321979 | HFO-1234ZE AND HFC-245FA CO-PRODUCTION PREPARATION PROCESS - Disclosed is an HFO-1234ze and HFC-245fa co-production preparation method. The HFO-1234ze and HFC-245fa are prepared through a two-stage gas phase fluorination reaction by using 1,1,1,3,3-pentachloropropane (HCC-240fa) as a raw material. With the processing method of the present invention, HFO-1234ze and HFC-245fa can be prepared at the same time, and the alkene is unlikely to polymerize or carbonize during the reaction, thus being suitable for industrialized promotion. | 11-12-2015 |
20150307420 | 1, 3, 3, 3-TETRAFLUOROPROPENE PREPARATION PROCESS - Disclosed is an HFO-1234ze preparation process. The present invention is realized by loading two fluorination catalysts into the same reactor, and controlling the temperature in each section. The preparation process of the present invention is of moderate reaction condition, stable catalyst activity, and simple process. | 10-29-2015 |
20140350312 | METHOD FOR PREPARING 2,3,3,3-TETRAFLUOROPROPENE - Provided are a fluorination catalyst for preparing 2,3,3,3-tetrafluoropropene and a method using the catalyst for preparing 2,3,3,3-tetrafluoropropene. The catalyst has the following structural formula: Crx(Y,Z) | 11-27-2014 |
