1. General Information
Formula: C4H10O2
CAS No.: 110-63-4
2. Application
1,4-Butanediol is a low-viscosity glycol used almost exclusively as an intermediate to synthesize other chemicals and polymers. The butanediol molecule maintains its original chemical identity only when used as a solvent. Since butanediol can undergo the typical reactions of a primary alcohol, it lends itself to a very large number of chemical modifications. As it is a difunctional molecule, most of its use is in the area of polymers, such as polyurethanes, polybutylene terephthalate (PBT), a large family of homopolymers and copolymers of N-vinyl-2-prrroidone, and copolyesterether thermoplastic elastomer (COPE).
3. Uses
Polybutylene Terephthalate (PBT), Thermoplastic Polyurethanes, Castable Polyurethanes, Reaction Injection Molding, Tetrahydrofuran, N-Methyl-2-Pyrrolidone (NMP), Gamma-Butyrolactone (GBL), N-Vinyl-2-Pyrrolidone (NVP)
