Beschreibung

General description

γ-Butyrolactone is a common food additive used to enhance the aroma of food. It is used as a solvent for lithium-ion batteries since it has a high flashing point, a low freezing point, a high boiling point, a low viscosity, and a high dielectric constant. It is also used as a plasticizer for the solid electrolyte of lithium batteries.

Application

γ-Butyrolactone can be used as:

• A plasticizer to prepare polymer electrolytes containing poly(epichlorohydrin-ethyleneoxide).
• A plasticizer to prepare quasi-solid-state electrolyte applicable in dye-sensitized solar cells.
• An electrolyte in combination with ionic liquids for applications in electrochemical devices.

Biochem/physiol Actions

Vorstufe von γ-Hydroxybuttersäure (GHB), blockiert die Dopaminfreisetzung.

Vorstufe von γ-Hydroxybuttersäure (GHB). Es blockiert die Freisetzung von Dopamin durch die Hemmung der Impulsleitung in dopaminergen Neuronen. Die Vorbehandlung mit γ-Butyrolacton ermöglicht den Nachweis einer autorezeptorvermittelten Dopaminausschüttung.
