Tetraidrofurano

Descrizione:

Tetraidrofurano (THF) è un liquido incolore e volatile con un odore distintivo di etere. È un etere ciclico e funge da solvente importante nella chimica organica grazie alla sua capacità di sciogliere un'ampia gamma di composti polari e non polari. Il THF ha un basso punto di ebollizione e una pressione di vapore relativamente alta, rendendolo utile in varie applicazioni, incluso come solvente per polimeri e nella produzione di prodotti farmaceutici. La sua struttura chimica presenta un anello a cinque membri contenente quattro atomi di carbonio e un atomo di ossigeno, contribuendo alla sua reattività e capacità di partecipare a varie reazioni chimiche, come la polimerizzazione. Il THF è igroscopico, il che significa che può assorbire umidità dall'aria, il che può influenzare le sue proprietà e reattività. È anche infiammabile e deve essere maneggiato con cura, utilizzando misure di sicurezza appropriate per evitare inalazione o contatto con la pelle. Inoltre, il THF può formare perossidi dopo un'esposizione prolungata all'aria, richiedendo pratiche adeguate di stoccaggio e maneggio per mitigare i rischi.
