💡 Commercial Applications
Gamma-Butyrolactone (GBL) is commonly used in industry as a solvent for various applications. It is utilized in the production of pesticides, herbicides, and pharmaceuticals due to its versatile properties. GBL is also used in the manufacturing of polymers, as it can enhance the solubility of certain compounds.
In the commercial sector, gamma-Butyrolactone is employed as a cleaning agent and degreaser for machinery and metal surfaces. Its ability to remove grease, oil, and other contaminants makes it a popular choice for industrial cleaning purposes. GBL is also utilized in the surface treatment of metals to improve their corrosion resistance and adhesion properties.
In the realm of drug and medication applications, gamma-Butyrolactone is a precursor to the production of gamma-Hydroxybutyric acid (GHB), a central nervous system depressant. GHB is used medically as a sedative and anesthetic, as well as for the treatment of insomnia and narcolepsy. However, due to its potential for misuse and abuse, GHB is a controlled substance in many countries.
While gamma-Butyrolactone has a wide range of commercial and industrial applications, it is important to note its potential health risks and regulatory restrictions. Users should handle GBL with care and ensure compliance with local regulations when utilizing it for various purposes.
⚗️ Chemical & Physical Properties
Gamma-Butyrolactone is a colorless, oily liquid with a slight characteristic odor.
With a molar mass of 86.09 g/mol and a density of 1.13 g/mL, gamma-Butyrolactone is similar in molar mass to sucrose (table sugar) but denser than water.
Gamma-Butyrolactone has a melting point of -45 °C and a boiling point of 204 °C, both significantly higher than common food items like butter or chocolate.
Gamma-Butyrolactone is miscible in water and has a low viscosity, making it more soluble and less viscous compared to most common food items like salt or sugar.
🏭 Production & Procurement
Gamma-Butyrolactone, an important chemical compound with various industrial applications, is primarily produced through the hydrogenation of succinic acid or maleic acid. This process typically takes place in the presence of a catalyst such as palladium or platinum. The resulting product is then purified through distillation to obtain high-quality gamma-Butyrolactone.
Gamma-Butyrolactone can be procured from chemical suppliers and manufacturers who produce and distribute the compound in large quantities for industrial use. It is typically transported in bulk containers such as drums or intermediate bulk containers (IBCs) to ensure safe and efficient delivery to end-users. Special precautions must be taken during transportation to prevent spills or leaks of gamma-Butyrolactone, as it is a highly reactive and potentially hazardous compound.
In addition to traditional procurement methods, gamma-Butyrolactone can also be obtained through online chemical suppliers and distributors. These suppliers typically offer gamma-Butyrolactone in various quantities, ranging from small research-grade samples to larger industrial quantities. Customers can place orders online and have the compound shipped directly to their desired location, following all necessary regulations and safety protocols for handling and storage.
⚠️ Safety Considerations
Safety considerations for gamma-Butyrolactone (GBL) include its potential to cause skin and eye irritation upon contact. Inhalation of GBL vapor may cause respiratory irritation and dizziness. GBL should be stored in a cool, dry, well-ventilated area away from incompatible materials, such as strong oxidizing agents.
Hazard statements for gamma-Butyrolactone include “Causes skin and eye irritation” and “May cause respiratory irritation.” Additionally, GBL may cause dizziness and drowsiness if inhaled. It is important to handle GBL with caution and wear appropriate personal protective equipment to minimize exposure risks.
Precautionary statements for gamma-Butyrolactone advise users to avoid skin and eye contact, as well as inhalation of vapor. It is recommended to use GBL in a well-ventilated area and wear protective gloves and eyewear when handling the substance. In case of accidental exposure, it is important to seek medical advice immediately and provide the SDS (safety data sheet) to medical personnel.
