Fluorine Lab in Freiburg
Figur 1: Fume hood during a fluorination reaction. The possible pressure range for 100 % F2 is from 1.0 x 10-2 to 5.0 bars. Batch fluorination reactions can be carried out in 120 ml PFA vessels or a Monel autoclave.
The fluorine lab in Freiburg was set up 2009. It was constructed minding the latest safety regulations for laboratories working with fluorine with a concentration up to 100 %. The laboratory itself is a security area, where only instructed or accompanied by an instructed persons have access to. In case of an unexpected leakage one sensor each for fluorine and hydrogen fluoride is installed and connected to an optical and acoustical alert. In the fume hood, were possible, fluorine resisting materials like stainless steel or perfluorinated polymers were used. The fluorine bottle is stored within a separate stainless steel container. The valves and pressure regulators near the bottle can be controlled from the outside of the containment. The line itself is constructed out of Swagelok® Monel tubes, valves and connectors. For scrubbing of fluorine containing waste gases a soda lime tower is connected to the line. plants or cylinders can be connected to the line by ¼ inch valves. The controller for the pressure gauges and the gas flow controller are installed outside the fume hood. Most reactions can be carried out while the fume hood is closed. In figure 1 (see above) the fume hood during a fluorination reaction and a scheme of the Monel line are shown.
