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.
In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...
Polymer fume fever, also known as “Teflon Flu,” is used to describe the flu-like symptoms a person can get after being exposed to fumes typically from polytetrafluoroethylene (PTFE).
A recent record number of cases of polymer fume fever, also known as "Teflon flu," are putting a spotlight on one of the most common causes of the condition, the use of nonstick pans. Over 265 ...
Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from Teflon pans, according to the National Capital Poison Center.
The fluorine-carbon bond is largely ionic, producing a strong dipole. The dipole prevents Teflon from being susceptible to Van der Waals forces, so other materials will not stick to the surface. [2] Teflon is commonly used to reduce friction in biomaterial applications such as in arterial grafts, catheters, and guide wire coatings.
A peripheral venous catheter is the most commonly used vascular access in medicine. It is given to most emergency department and surgical patients, and before some radiological imaging techniques using radiocontrast, for example. In the United States, in the 1990s, more than 25 million patients had a peripheral venous line each year. [2]
