FAQ
What is Tetrahydrofuran (THF) and what are its common uses?
Tetrahydrofuran (THF) is a saturated cyclic ether with the chemical formula (CH2)4O. It is a colorless liquid with an ether-like odor. THF is widely used as a solvent in various industries, including pharmaceuticals, polymers, and organic synthesis. It is also commonly used as a reaction medium in Grignard and organolithium reactions.
What does it mean for THF to be "dry" with a maximum of 0.0075% water content?
When THF is said to be "dry," it means that it has been purified to remove moisture or water content. The maximum allowable water content in THF is 0.0075%, which ensures that the solvent is free from excess water that could interfere with chemical reactions or reactions that are sensitive to water.
How is THF stabilized with approximately 300 ppm of BHT (Butylated hydroxytoluene) beneficial?
THF is a highly reactive solvent that can be prone to oxidation, which can lead to the formation of peroxides. Stabilizing THF with BHT, an antioxidant, helps prevent the formation of peroxides and extends the shelf life of the solvent. This ensures that the THF remains stable and suitable for use in various applications without the risk of peroxide formation.
What is ACS grade THF and why is it important in certain applications?
ACS grade THF refers to Tetrahydrofuran that meets the specifications outlined by the American Chemical Society (ACS) for purity and quality. ACS grade THF is of higher purity compared to other grades, making it suitable for analytical and laboratory applications where the presence of impurities can negatively impact results. Using ACS grade THF ensures the reliability and accuracy of experimental outcomes.
How can customers ensure the safe handling and storage of THF stabilized with BHT?
Customers should store THF stabilized with BHT in a cool, dry place away from sources of ignition, heat, and direct sunlight. The solvent should be kept in a tightly closed container to prevent moisture absorption and contamination. Proper ventilation should be maintained when handling THF, as it can release vapors that may be harmful if inhaled. Additionally, appropriate personal protective equipment, such as gloves, goggles, and a lab coat, should be worn when working with THF to minimize the risk of skin contact or inhalation.
