Tetrahydrofuran Uses

Tetrahydrofuran is a colorless and transparent liquid with an ether-like odor. THF can be miscible with water. Miscible with water can dissolve alkaloids such as cellulose acetate and caffeine, and the dissolution performance is better than that of tetrahydrofuran alone. General organic solvents such as ethanol, ether, aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, etc. can be well dissolved in tetrahydrofuran. Oxidation in air easily produces explosive peroxides. THF has no corrosive effect on metals and has an erosive effect on many plastics and rubbers. Because of its low boiling and flash points, Tetrahydrofuran is prone to fire at room temperature. When stored, oxygen in the air can produce explosive peroxides with tetrahydrofuran. Peroxides form more easily in the presence of light and in the absence of water. Therefore, reducing substances such as 0.05%~1% hydroquinone, resorcinol, p-cresol or ferrous salts are often added as antioxidants to inhibit the generation of peroxides. The toxicity of this product is low, and the operator should wear protective equipment.
