Highly flammable. Slightly soluble in water; Soluble in ethanol and ether. When exposed to oxygen, ethers often form unstable peroxides. Ethyl, isobutyl, ethyl tert butyl, and ethyl tert amyl ethers are particularly dangerous in this regard. Sometimes it can be observed that ether peroxides deposit in the form of transparent crystal Chemicalbooks on containers or along the liquid surface. Colorless liquid with chemical properties. Melting point -92 , boiling point 93.8 , relative density 0.7888 (20/4 ), refractive index 1.4026, flash point -9. Easily soluble in alcohols and ethers, slightly soluble in water.
