Perfluorotributylamine (PFTBA) is a liquid from the group of perfluorocarbons , which strongly promotes the greenhouse effect in the atmosphere .

properties

Perfluorotributylamine is a water-insoluble and chemically inert, colorless liquid. Researchers at the University of Toronto found that PFTBA as a gas has 7100 times the global warming potential of carbon dioxide . Since it is only found in traces in the atmosphere, its overall effect is only 1 / 10,000 as great as that of carbon dioxide.

use

Among other things, PFTBA is used in the electronics industry (trade name e.g. Fluorinert FC-43) for heat tests and vapor phase soldering as well as in mass spectrometry as a calibration substance. Preparations containing perfluorotributylamine (e.g. Fluosol) and other perfluorocarbons are suitable as blood and erythrocyte substitutes and are also used in ophthalmology and in particle counters in aircraft.
