Patent number: 6365246Abstract: An economical means of safely “containing” or “packaging” commercial electrophilic fluorination agents whereby these agents are readily stored and transported in a package, typically without loss of “F+” activity, and in a form which is readily and directly useable, i.e., in solution or a slurry. Importantly, the solution/slurry medium provides a tremendous safety margin for storage and transportation since the solution medium has an enormous ability to absorb heat (due to the latent heat of vaporization of the liquid) relative to the contained active fluorination agent.Type: GrantFiled: September 29, 1998Date of Patent: April 2, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Robert George Syvret, James Joseph Hart, Andrew Joseph Woytek, Frank Michael Prozonic
