A butanediol derivative, Gamma-Butyrolactone (GBL) is a colorless liquid with a high boiling point and low odor. GBL is soluble in alcohols, aromatic hydrocarbons, esters, ethers, ketones and water. It is only partially miscible with aliphatic hydrocarbons and is slightly hygroscopic.
Note: In the United States, the sale and distribution of gamma-butyrolactone and 1,4-butanediol may be regulated by federal and/or state requirements. In Europe, the same may apply following Country requirements. Other Countries outside of the United States and Europe have also begun to implement specific requirements. Requests for these products for industrial use will be approved by Lyondell as appropriate. We will report questionable requests for these chemicals to the Drug Enforcement Agency, to the European Country Authorities and other relevant agencies. For international transactions of GBL less than 4000 Kg per container, Lyondell is required by law to notify the Drug Enforcement Administration a minimum of 15 days prior to the transaction. Please refer to applicable country, federal and state documents for additional transaction requirements. If you have any questions or concerns, please contact us at (+1) 713-309-2561.
Benefits and Applications
GBL is a good solvent for industrial cleaning products, including paint strippers and de-inking and adhesive removers. It also has application as a chemical intermediate in agrichemicals, pharmaceuticals and dyes; and as a production solvent in textile finishing, printing and epoxy coatings.
Toxicology/Regulatory
Overexposure may cause eye and skin irritation, and therefore appropriate precautions should be observed while handling. Adequate ventilation is required when handling as well.
For more safety/health information, please request Lyondell's material safety data sheet (MSDS) for GBL.
Storage and Handling
Stainless steel (304,316), mild steel or aluminum are all satisfactory for storage tanks. Zinc should be avoided. Long-term storage may result in increased color and/or moisture.
Keep GBL away from strong oxidizing agents, heat, sparks and flame.
GBL is in equilibrium with 4-hydroxybutyric acid in aqueous solution. The steady state concentration of 4-hydroxybutyric acid increases with increasing water concentration.
