Description générale

The product is tetrahydrofuran (THF) and it contains 250ppm BHT (Butylated hydroxytoluene) as an inhibitor. THF is widely employed as a solvent. It constitutes the key fragment of various natural products (polyether antibiotics). THF forms 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).

Application

Tetrahydrofuran has been used as a solvent for the preparation of sol-gel solution for coating solid phase microextraction (SPME) fibers in a study.

It 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.
