- Product Applications
- 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 copolyester-ether thermoplastic elastomer (COPE).

Storage & Handling
- Storage Conditions
- The storage tank must be provided with external or internal heating source to maintain a temperature of about 50°C.
- Solidified 1,4-Butanediol can be molten by being heated in melting room about 70°C for 24 hours.
- Do not heat it 80°C over It is very important to protect 1,4-Butanediol against to moisture because it is hygroscopic.
- Therefore it is recommended that 1,4-Butanediol should be stored in completely enclosed tank or container under a dry nitrogen blanket. As 1,4-Butanediol is ignitable, water spray, foam and/or powder may be used for firefighting.
- Shelf life of 1,4-Butanediol is approximate 2 years, under condition that the product is stored in unopened, tightly sealed original container at no greater than 80°C and is not contacted with moisture under a dry nitrogen blanket.
- Shelf life is only guidance and is not a guarantee because there are various possibilities in site of end users to affect the quality of 1,4-Butanediol.
