설명

일반 설명

Tetrahydrofuran (THF) is a heterocyclic compound (cyclic ether). It is colorless, has low viscosity, and good solubility in a wide range of solvents. It is widely used as a solvent in organic synthesis, being very popular in reactions with organometallic compounds and Grignard reagents. Due to organic peroxides formation on long term storage, THF is usually stabilized by adding butylated hydroxytoluene (BHT). BHT removes the free radicals required for the peroxide formation.

애플리케이션

Tetrahydrofuran (THF) is used as a solvent in the following processes:

• Organic synthesis

a) Grignard
b) Organometallic compounds
c) Reformatsky
d) Lithiation
e) Hydride reduction
f) Metal-catalyzed coupling (Heck, Stile, Suzuki)
g) Lewis acid mediated reactions

• Crystallization
• Polymerization. Ex. RAFT (Reversible Addition-Fragmentation Chain Transfer) polymerization of p-acetoxystyrene
• Coatings
• As an O-donor ligand to form coordination complexes
• As mobile phase solvent in high-performance liquid chromatography

특징 및 장점

ACS solvents meet or exceed the high standards of the American Chemical Society (ACS) ,with test specifications that are specialized to every compound. According to the American Chemical Society, ACS reagent grade implies that it is a substance of sufficient purity to be used in most chemical analyses or reactions.
