Product Specification / Models
Application / Models
1,4- butyrolactone as spices, pharmaceutical intermediates, widely used. As a high boiling point solvent, strong solubility, electric properties and good stability, the use of safety. As a kind of proton type powerful solvent, can dissolve most low molecular polymer and part of high molecular polymer, can be used as a battery electrolyte, to replace the strong corrosive acid. In the polymerization can be used as the carrier and participated in the polymerization reaction. Can be used for pyrrolidone, butyric acid, succinic acid, to paint the potions, in the synthesis of medicine, perfume and other fine chemicals with a wide application. Also used as a resin solvent, is high safety / toxicity environmentally friendly solvent. In the field of polyurethane, polyurethane can be used as a viscosity modifier (active diluent), and polyurethane and amino paint curing agent.
