Latest Patents

Crampton holds a patent for a process aimed at the recovery of ammonia and fluoride values from ammonium. The patent describes a method where components of aqueous ammonium fluoride solutions are recovered as ammonia and potassium fluoride. This is achieved by adding potassium hydroxide, distilling to remove and secure the ammonia, and concentrating the remaining solution. The process further involves combining the concentrated solution with a water-soluble, dipolar, aprotic solvent, such as N-methylpyrrolidone, and distilling to remove the remaining water. The result is potassium fluoride obtained as a slurry in the solvent, which is useful in replacing chloride in heterocyclic and aryl chlorides with fluoride.
