Abstract
The present invention provides an improved process for preparation of 2,3,3,3-tetrafluoropropene, wherein recyclization of the reaction by-products result in equilibrium between feed and outlet composition.
Claims6
A process for preparation of 2,3,3,3-tetrafluoropropene consisting of:
- a) providing a heat source in a reactor;
- b) providing a mixture of methylchloride and tetrafluoroethylene, said mixture is either premixed or added separately, in the reactor to obtain a mixture;
- c) contacting the mixture with heat source in the presence of an initiator to obtain a reaction mixture comprising 2,3,3,3-tetrafluoropropene;
- and
- d) isolating 2,3,3,3-tetrafluoropropene,
- wherein, heat source is either an electric heater or a furnace,
- wherein, the initiator is selected from a group consisting of carbon tetrachloride, chloroform, or a mixture thereof.
