| titleOfInvention | High purity E-1-chloro-3,3,3 ,-trifluoropropene and preparation method thereof |
| abstract | The invention discloses high purity E-1-chloro-3,3,3 ,-trifluoropropene (1233zd (E)) and preparation method thereof.More specifically, the invention discloses preparation and be substantially free of poisonous impurity (such as 2-chloro-3,3,3 ,-trifluoropropene (1233xf), a chlorine tetrafluoeopropene (1224) and 3,3,3-trifluoropropyne) the method for 1233zd (E).Present invention also offers the method preparing high purity 1233zd (E), wherein the concentration of 1233xf and 1224 is in or lower than 200ppm (1,000,000/a) and the concentration of 3,3,3-trifluoropropyne impurity is in or lower than 20ppm.If use pure 1,1,1,3,3-pentachloropropane as parent material, the formation of 1233xf impurity can be avoided.If also find to use liquid phase manufacture method, then avoid the formation of 1233xf. |
