2(4H)-Benzofuranone, 5,6,7,7a-tetrahydro-3,6-dimethyl- - Introduction
FEMA 3764, often referred to simply as THF-DME, is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
THF-DME is a colorless liquid with a characteristic furan aroma. It is a polar compound soluble in many organic solvents, but insoluble in water. It has a melting point of -87°C, a boiling point of 85°C and a density of 0.884g/cm³. It is a relatively stable compound and does not easily decompose at room temperature.
Use:
THF-DME are commonly used as chemical reagents and reaction solvents. It is often used in the preparation of catalysts, oxidation reactions, reduction reactions and acylation reactions in organic synthesis. It is also commonly used in Raman spectroscopy in organic synthesis.
Preparation Method:
The preparation method of THF-DME is relatively simple, and it is usually synthesized by adding dimethyl ether (DME) on the basis of existing THF (tetrahydrofuran). This process can be carried out at an appropriate temperature and pressure.
Safety Information:
THF-DME has a certain toxicity to the human body. It can enter the human body through inhalation, intake or through skin contact. Therefore, safety procedures should be followed during use, including wearing protective glasses, gloves and respiratory protection. Immediately after contact, the affected skin area should be thoroughly washed with water. If you swallow or inhale large amounts of THF-DME, seek medical attention immediately. When storing, it should be kept in a closed container, away from fire and oxidant to prevent it from being flammable and explosive.
