(retenton of stereochemistry may be further enhanced by the addition of a fluoride salt).
Graphite is used as it has relatively low costs and compatibility with liquid fluoride salts.
Fluorine-18 could be produced more easily in a cyclotron as a fluoride salt and was easier to handle than fluorine gas.
The one-fluid design includes a large reactor vessel filled with fluoride salt containing thorium and uranium.
In hot fluoride salts, hydrogen will be present as elemental tritium.
Like other fluoride salts, olaflur is toxic when given in high doses over an extended period of time.
However, it cannot oxidize fluoride salts to fluorine.
The final product is a fluoride salt which is relatively easy to solubilize.
Various fluoride salts (e.g. sodium, potassium, tetra-n-butylammonium fluorides) are popular for this purpose.
The technique is also used to analyze fluoride salts.
