γ-Butyrolactone is a high boiling point solvent with strong solubility, non-toxic, safe and convenient management, used as extraction agent for butadiene, aromatics and advanced grease in petroleum processing; used as spinning solvent for acrylonitrile fibers in chemical fiber industry; used as a solvent for wool, nylon, and other materials; used as a solvent for the production of wool. It is also used as a dyeing agent for acrylonitrile and other fibers.
In addition, it can also be used as a battery, capacitor production, and coloring color rolls. Biochemically, it is a precursor of γ-hydroxybutyric acid (GHB). It prevents the release of dopamine by inhibiting the impulse flow of dopaminergic neurons. Pretreatment with γ-butyrolactone detects the autoreceptor-induced release of dopamine.
