Diethyl ether peroxides can be detected with a potassium iodide (KI) solution in acetic acid or potassium iodide/starch paper. A positive test results in the formation of iodine (I2) that causes a yellow or brown color of the ether phase or a dark bluish spot on the paper strip.

Diethyl ether hydroperoxide and its condensation products are blamed … See more Diethyl ether hydroperoxide can be formed by the photooxygenation of diethyl ether. This is a radical process, driven by UV excitation of molecular oxygen into a more reactive form. Its … See more WebAn epoxide is a cyclic ether with three ring atoms. These rings approximately define an equilateral triangle, which makes it highly strained. The strained ring makes epoxides more reactive than other ethers. Simple epoxides are named from the parent compound ethylene oxide or oxirane, such as in chloromethyloxirane.
