Butyrolactone is a strong solubility, non-toxic, safe and convenient use and management of high boiling point solvent, used as extraction agent of butadiene, aromatic, senior lubricating grease in petroleum processing; used as a solvent spinning acrylic fibers in chemical fiber industry, dyeing auxiliaries, nylon, wool is acrylonitrile fibers. In organic synthesis, GBL also has a wide range of uses, it is the synthesis of alpha pyrrolidone, N- methyl pyrrolidone, vinyl pyrrolidone, acetyl gamma butyrolactone, Cyclopropylamine and other raw materials, synthetic pesticides, herbicides, is drug piracetam, ciprofloxacin, vitamin B1, intermediate chlorophyll etc.. Also used in the synthesis of chlorophenoxy acid herbicides, plant growth regulator.


How GBL works

GBL is a non-toxic transparent liquid in the shape of oil. It can be mixed with water and dissolved by ethanol, ether, benzene and acetone. It can dissolve many other organic and inorganic compound. Using GBL is very safe and convenient, because it is a liquid with high boiling, powerful solvency, good electrical and stability properties.

GBL is an important organic synthetic raw material and a fine solvent. It is mainly used as synthetic pyrrolidone series products cyclopropylamine acetyl-r-butyrolactone, Besides these, GBL is also used as solvent for agricultural chemicals, polymer, dyestuff and printing. Using GBL as raw material, we can produced aromatic chemicals, medicinal intermediates and rust remover.


(1). GBL can be used to produce a-pyrrolidone, 1-Methyl-2-pyrrolidinone , polyvinyl pyrrolidone, and α-Acetyl-γ-butyrolactone, etc.
(2). GBL can be used as anaesthetic and tranquilizer, used to produce ciprofloxacin and interferon, as the intermediate of vitamin and rolicyprine;
(3). GBL is the intermediate of plant growth stimulator and insecticide.
(4). GBL is a good antioxidant, plasticizer, extractant, adsorbent, dispersant, fixative and curing agent; Moreover, it can also be used in battery, capacitor and development of color film.
