| titleOfInvention |
Process for the preparation of difluoromethane |
| abstract |
A liquid phase fluorination process for producing difluoromethane without corrosion is provided. In the process of this invention, methylene chloride and hydrogen fluoride are reacted in a reactor made of fluorinated polymer to produce a reaction product while a heated recycle stream of process reactants is fed into the reactor. |
