| Hazard Information | Back Directory | 【General Description】
A clear colorless liquid with an ethereal odor. Less dense than water. Flash point 6°F. Vapors are heavier than air. | 【Reactivity Profile】
TETRAHYDROFURAN(109-99-9) reacts violently with oxidizing agents leading to fires and explosions [Handling Chemicals Safely 1980. p. 891]. Subject to peroxidation in the air. Peroxides or their products react exothermically with lithium aluminum hydride [MCA Guide for Safety 1973]. Thus, use as a solvent for lithium aluminum hydride has led to fires. Using potassium hydroxide or sodium hydroxide to dry impure TETRAHYDROFURAN(109-99-9) that contains peroxides has resulted in explosions. A violent explosion occurred during the preparation of sodium aluminum hydride from sodium and aluminum in a medium of TETRAHYDROFURAN(109-99-9) [Chem. Eng. News 39(40):57. 1961]. THF forms explosive products with 2-aminophenol [Lewis 3227]. | 【Air & Water Reactions】
Highly flammable. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Soluble in water. | 【Health Hazard】
Vapors cause nausea, dizziness, headache, and anesthesia. Liquid can de-fat the skin and cause irritation. Liquid also irritates eyes. |
