There are several methods for fluorinating organic compounds
There are several methods for fluorination of organic compounds, including selective fluorination. Fluorides of alkali metals or fluorides of antimony, mercury, and silver can be used to convert halogenated alkanes or sulfonic acid esters into fluorinated alkanes. The reaction is generally carried out in an anhydrous polar medium; Antimony pentachloride can also be used as a catalyst for fluorinat

Unique characteristics of 5 fluorinated polymers
1. Fluorinated polymers have universal chemical compatibility Almost all fluoropolymers have amazing resistance to acids, solvents, and bases, which means they can remain in contact with other substances without any detectable chemical reactions. This makes them materials for applications that require anti-corrosion protection.
