For vacuum reaction in a reactor, where the medium contains HF, chlorine gas, and acetic acid at a temperature of 140°C, what material should be used?
Thread Content
I would like to ask everyone: It is a vacuum reaction in a reactor, with media containing HF, chlorine gas, and acetic acid, at a temperature of 140°C. What material would be suitable for use? Previously, PTFE lining was used, but it didn’t work – under vacuum conditions the fluorine-lined layer would be pulled off. I’m not sure if there are any other materials that can be used, apart from those coated with gold or silver. :P
It depends on the size of your reactor; if it’s small, a PFA-lined transfer molding tank with a dovetail groove and a grid-shaped plate structure should work.
It’s a bit large; transfer molding might not be possible. Ask the manufacturers of PFA-lined tanks to see if high-temperature rotational molding is possible. To withstand negative pressure, the shape and structure must be properly designed.
PFA can be applied by spraying, with a spray thickness of around 2 mm.
