g-Butyrolactone (GBL) is a colorless, high boiling, low odor liquid and a good solvent. It is soluble in alcohols, aromatic hydrocarbons, esters, ethers, ketones and water, and only partially miscible with aliphatic hydrocarbons. GBL is slightly hygroscopic.
GBL is a good solvent for industrial cleaning products like paint strippers and deinking and adhesive removers. It also has application as a chemical intermediate in agrichemicals, pharmaceuticals and dyes; and as a production solvent in textile finishing, printing and epoxy coatings.
Textiles:
GBL is used as a spinning and coagulating solvent for polyacrylonitrile, as a surface treatment for textile fibers and as an intermediate for dyes and textile assistants.
Consumer Product Uses: GBL is used in a variety of applications including detergents, air fresheners, household cleaners, and
paint removers. Its combination of high flash point, low volatility and broad solvency make GBL an excellent replacement for regulated solvents.
Agricultural Uses:
GBL is used as a carrier solvent and as a chemical intermediate for herbicides, insecticides, and fungicides.
Other Solvent Uses:
GBL is a solvent for many polymers. Polyacrylonitrile, polyvinyl chloride, polyvinylcarbazole, polystyrene, poly-amides and cellulose acetate are just a few polymers easily solubilized by GBL. GBL is very effective as a selective solvent in the petroleum industry. Uses as acetylene clean-up, aromatic/paraffin, olefin/paraffin and naphthene
separations solvents are typical. Inorganic compounds and azeotropic mixtures are easily separated by the use of GBL. Selective extraction of
hydrogen sulfide and carbon dioxide from natural or process gas streams is also a common use. GBL is also an excellent solvent for many chemical
processes either alone or in combination with other solvents.
