- PROCESSES FOR PRODUCING 2-CHLORO-1,1,1,2-TETRAFLUOROPROPANE AND 2,3,3,3-TETRAFLUOROPROPENE
-
To provide processes for efficiently and economically producing 2-chloro-1,1,1,2-tetrafluoropropane (R244bb) and 2,3,3,3-tetrafluoropropene (R1234yf) in an industrially practical manner. A process for producing 2-chloro-1,1,1,2-tetrafluoropropane, which comprises a chlorination step of reacting 1,2-dichloro-2-fluoropropane and chlorine in the presence of a solvent under irradiation with light to obtain 1,1,1,2-tetrachloro-2-fluoropropane, and a fluorination step of reacting the 1,1,1,2-tetrachloro-2-fluoropropane obtained in the chlorination step and hydrogen fluoride in the presence of a catalyst to obtain 2-chloro-1,1,1,2-tetrafluoropropane, and a process for producing 2,3,3,3-tetrafluoropropene, which comprises dehydrochlorinating it in the presence of a catalyst.

- Fluorination process using hydrogen fluoride-containing fluorinating agents
-
Fluorination processes using hydrogen fluoride-containing fluorinating agents that are safely and easily handled, transported, and stored and that also exhibit good reactivity are provided. More particularly, the invention provides processes for producing fluorinated products using fluorinating agents comprising hydrogen fluoride and a carrier that may be an acid salt or a water-soluble polymer.

- REACTION OF ALKANES, ETHERS AND ALIPHATIC KETONES WITH THE SF4-HF-Cl2 SYSTEM
-
The reaction of alkanes, ethers, and aliphatic ketones with the SF4-HF-Cl2 system takes place through formation of unsaturated compounds followed by addition of the chloride and fluoride ions.The presence of sulfur tetrafluoride in the rection mixture pro
