Perfluorotributylamine (PFTBA) is a liquid whose molecular structure consists of three butyl moieties connected to an amine center, in which the hydrogen atoms have all been replaced with fluorine. The compound is produced by the electronic industry, along with other perfluoroalkyl amines.[1] It is used as an ingredient in Fluosol and in some Fluorinert coolant liquids.[2]
In 2013, this liquid was shown by researchers at the University of Toronto to be a greenhouse gas, with warming properties more than 7,000 times that of carbon dioxide over a 100 year period,[3][4] and that, as such, it is the most potent greenhouse gas ever discovered.[5] Its concentration in the atmosphere is approximately 0.18 parts per trillion. The researchers also reported that the gas can persist in the atmosphere for up to 500 years.
