Abstract
A process for preparing a fluorinating reagent from a calcium-containing compound is disclosed. The process bypasses the requirement to form hydrofluoric acid. The fluorinating reagent can be used to prepare high-value fluorochemicals.
Claims20
A method of manufacturing an activated fluorination reagent, the method comprising:
- combining a first salt, the first salt comprising calcium and fluorine, with a second salt, the second salt comprising an anion, which said anion when combined with Ca2+ to form a third salt has a lattice energy greater than 2450 KJ/mol, to form a salt mixture;
- and
- applying mechanical force to the salt mixture to yield the activated fluorination reagent.
