A divided flow cell is used for electrolysis of NaBr aqueous solution.The anolyte containing Br 2 and catholyte containing NaOH are produced simultaneously and in turn to epoxide HFP to HFPO.
PVC, Teflon and fluorion diaphragm were found to be better than glass as materials of diaphragm cell for their advantages in corrosion resistance as well as less electric resistance.
The key technology and technics,which use Simons electrolyze trough with a falcial anode to synthesize lithium fluoroalkylphosphates,are discussed in this paper.
When used together with a solar cell to power the electrolyzer, the method required just one-fourth the energy to grow the same amount of food created by sunlight and natural photosynthesis.
