A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.
Trifluoroethanol is produced industrially by hydrogenation or the hydride reduction of derivatives of trifluoroacetic acid, such as the esters or acyl chloride. [1]TFE can also be prepared by hydrogenolysis of compounds of generic formula CF 3 −CHOH−OR (where R is hydrogen or an alkyl group containing from one to eight carbon atoms), in the presence of a palladium containing catalyst ...

2017 3M net sales for 2017 were $31.657 billion compared to $30.109 billion in 2016. [72] 2017 The Fire Fighting Foam Coalition's 2017 fact sheet said that the short chain (C6) fluorosurfactants which are replacing the longer C8 in AFFF are "low in toxicity and not considered to be bioaccumulative based on current regulatory criteria."
