What is GBL (Gamma-Butyrolactone)?

GBL (Gamma-Butyrolactone) is a versatile, high-purity industrial solvent and chemical intermediate with the CAS number 96-48-0 . This clear, colorless liquid is a 5-membered-ring lactone with the molecular formula C₄H₆O₂ and a molecular weight of 86.1 g/mol .

Key identifiers for GBL:

• CAS Number: 96-48-0

• Molecular Formula: C₄H₆O₂

• Synonyms: 4-Butyrolactone, Dihydro-2(3H)-furanone, 1,4-Butanolide 

• Appearance: Clear colorless liquid with faint ester-like odor 

• Specific Gravity: 1.13 (25/4°C) 

GBL is a polar, aprotic solvent with a unique combination of solvent and electrical properties, making it valuable across multiple industries . It is soluble in water, alcohols, aromatic hydrocarbons, esters, ethers, and ketones .

Primary Industrial Applications of GBL

GBL serves two main industrial purposes:

1. Solvent Applications:

• Solvent for photosensitive resins and special inks 

• Electrolyte solvent for capacitors and lithium batteries 

• Spinning and coagulating solvent for polyacrylonitrile 

• Selective solvent in the petroleum industry
