tetrafluoroethylene , TFE (skrót)

An important application of R-22 is as a precursor to tetrafluoroethylene.

While working with a cylinder of tetrafluoroethylene, he was unable to release the gas although the weight had not changed.

The key step employs an unusual mixture of hexafluoro-2-propanol and tetrafluoroethylene as solvent.

While working with tetrafluoroethylene gas, he noticed that a previously-pressurized cylinder had no pressure remaining.

This difference is significant because difluorocarbene is a precursor to tetrafluoroethylene.

Chlorodifluoromethane is then converted into tetrafluoroethylene, the main precursor to Teflon.

The epoxide of tetrafluoroethylene is even more unstable with respect to trifluoracetyl fluoride.

Thus strong pi backbonding ligands are tetrafluoroethylene, tetracyanoethylene, and hexafluoro-2-butyne.

The method is illustrated in figure 10.5 for poly(tetrafluoroethylene) where glass and other transitions are readily detected.

It is formed by the polymerization of tetrafluoroethylene:

Under reaction conditions, telomers form with different carbon chain lengths of an even number, as products mostly contain two to six tetrafluoroethylene taxogens.

R-22 is a versatile intermediate in industrial organofluorine chemistry, e.g. as a precursor to tetrafluoroethylene.

A large scale application of carbenes is the industrial production of tetrafluoroethylene, the precursor to Teflon.

Two polymers which exist in the all trans state in the crystal are polyethylene and poly(tetrafluoroethylene).

In dissecting the cylinder, he found a mass of white solid in a quantity similar to that of the tetrafluoroethylene gas.

It has also been used as a chain transfer agent in the emulsion polymerization of propylene tetrafluoroethylene copolymer.

Octafluorocyclobutane is produced by the dimerization of tetrafluoroethylene and the reductive coupling of 1,2-dichloro-1,1,2,2-tetrafluoroethane.

Polyethylene and poly(tetrafluoroethylene) are both sufficiently symmetrical to be considered as smooth stiff cylindrical rods.

FClO can also react with tetrafluoroethylene:

However, many fluorotelomers, such as fluorotelomer alcohols, are fluorocarbon-based because they are synthesized from tetrafluoroethylene.

The major use of chloroform today is in the production of the chlorodifluoromethane, a major precursor to tetrafluoroethylene:

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications.

Fluorinated ethylene propylene or FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene.

Fluorotelomer olefins are synthesized using a telomerization of tetrafluoroethylene taxogens (monomers), followed by an ethylene insertion.

Fluoropolymers were discovered in 1938 by Dr. Roy Plunkett when he accidentally polymerized tetrafluoroethylene to form polytetrafluoroethylene.
