El THF es un disolvente aprótico, moderadamente polar. Es capaz de disolver un amplio rango de compuestos. El dietil éter puede ser a menudo sustituido por THF, especialmente cuando se requiere un mayor punto de ebullición. Así pues, el THF, como el dietil éter, es usado a menudo en hidroboraciones de alquenos. Ambos éteres tienen un átomo de oxígeno que puede coordinarse a un átomo de boro electrodeficiente, … Web24 Jul 2024 · Tetrahydrofuran is a versatile solvent, which is one of its main uses. It acts as an industrial solvent for making polyvinyl chloride (PVC), the plastic that the majority of indoor plumbing is made out of, and it also dissolves PVC, and therefore is a primary ingredient in PVC adhesives. It is also used in PVC reactor cleaning and PVC film casting.
