Properties 
Y -butyrrolactone is a non-toxic transparent liquid in the shape of oil. It can be mixed with water and dissolved by ehtanol, ether. Benzene and acetone. It can dissolve many other organic and inorganic. Using Y-butyrrolactone is very safe and convenient, because it is liquid with high boiling, powerful solvency, good electrical and stability properties. 
Usage: 
A-butyrrolactone is an important organic synthetic raw material and a fine Solvent. It is mainly used as synthetic pyrrolidone series products cyclopropylamine acetyl-γ -butyrrolactone butyrrolactone, etc. Besides these, y-butyrrolactone si also used as solvent for agricultural chemicals, polymer, dyestuff and printing. Using γ -butyrrolactone as raw material, we can produced aromatic chemicals, medicinal intermediates and rust remover.
