| Chemical properties | Gamma-Butyrolactone (GBL) is a colorless oily liquid. It is miscible with water and the general organic and slightly soluble in aliphatic hydrocarbons. GBL has been characterized as having an intense bitter taste with faint to pleasant odor. |
| Uses | Gamma-Butyrolactone (GBL) has widespread industrial use. It is a common solvent found in paint strippers, nail polish removers, stain removers and circuit board cleaners. It is also a common intermediate in industrial chemistry including the manufacture of pyrrolidones and in some pharmaceuticals. Gamma-Butyrolactone is an important organic synthesis intermediate which can be used to synthesize indole butyric acid, butyric acid, succinic acid, α-pyrrolidone, N-methylpyrrolidone, vinyl pyrrolidone, acetyl-γ-butyrolactone, cyclopropylamine, ciprofloxacin, vitamin B1, chlorophyll and so on; It is a non-toxic high boiling point solvent with high solubility and safe and convenient usage and management; It is used as an extractant for butadiene, aromatic, advanced grease petroleum processing; It is used as an acrylonitrile fiber spinning solvent in the chemical fiber industry. It is a thinner and curing agent commonly used in wool, nylon, acrylonitrile and other fiber dyeing auxiliaries and other chemical industries. |
| Production | Maleic anhydride hydrogenation method is an advanced technology developed in 1970s. It can produce tetrahydrofuran and γ-butyrolactone in any proportion with a hydrogenation reaction, and the usual ratio is tetrachlorofuran: γ-butyrolactone = 3-4:1. There are many production enterprises, but usually in small scale. The average level is 300t/a. The production capacity account for 30% of the total domestic production capacity. 2.1, 4-butanediol dehydrogenation reactor is a tube array reactor, filled with flake copper catalyst (with zinc oxide as the carrier). The reaction temperature is controlled at 230-240 ° C. The yield of the product is obtained by reduced pressure distillation of and the yield is above 77%. |

| Description | Dihydro-2(3H)-furanone. An endogenous neuroregulator made from gamma-amino butyrate and the precursor of gamma hydroxybutyrate. It causes selective increase of brain dopamine by inhibiting its release from nerve terminals. The compound has sedative properties at low doses and produces surgical anesthesia at high doses. It is also used as an industrial solvent and precursor. |
| Chemical Properties | γ-Butyrolactone is oily, colorless, clear liquid. It has a faint, sweet, aromatic, slightly buttery odor. γ-Butyrolactone is a lactone. It is hydrolyzed under basic conditions, for example in a sodium hydroxide solution into sodium gamma-hydroxybutyrate, the sodium salt of gamma-hydroxybutyric acid. Under acidic conditions it forms an equilibrium mixture of both compounds. These compounds then may go on to form a polymer. |
