Descrição geral

Tetrahydrofuran (THF) is a saturated cyclic ether mainly used as an organic solvent. On long term storage it forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for the peroxide formation. THF constitutes the key fragment of various natural products (polyether antibiotics). THF can form a double hydrate with hydrogen sulfide. Crystal structure of this double hydrate has been investigated by three-dimensional single-crystal studies. Butane-1,4-diol is formed as an intermediate during the synthesis of THF. Hot THF is useful for the dissolution of polyvinylidene chloride (PVDV).

Aplicação

Tetrahydrofuran may be used for the dissolution of poly-ε-caprolactone (PCL) and 1,3-diaminopentane, during the preparation of poly-ε-caprolactone (PCL)-hydroxyapatite (HA) scaffolds and acrylate-terminated poly(5-amino-1-pentanol-co-1,4-butanediol diacrylate) (C32)- 1,3-diaminopentane (117) polymer, respectively.
