Product Application
Polymerization
In the presence of strong acids, THF converts to a linear polymer called poly(tetramethylene ether) glycol (PTMEG), also known as polytetramethylene oxide (PTMO)
As a solvent
The other main application of THF is as an industrial solvent for polyvinyl chloride (PVC) and in varnishes. THF is often used in polymer science. THF is used as a component in mobile phases for reversed-phase liquid chromatography. THF is used as a solvent in 3D printing when using PLA plastics. It can be used to clean clogged 3D printer parts, as well as when finishing prints to remove extruder lines and add a shine to the finished product. Recently THF is used as co-solvent for lithium metal batteries, helping to stabilize the metal anode.
Laboratory use
In the laboratory, THF is a popular solvent when its water miscibility is not an issue.
Reaction with hydrogen sulfide
In the presence of a solid acid catalyst, THF reacts with hydrogen sulfide to give tetrahydrothiophene.
