Ozonation of pure aqueous solutions of the polar aliphatic refractory triethylene glycol dimethyl ether (TEGDME) which is a typical representative of organic solutes of oil reclaiming wastewaters does not lead to effective mineralization unless high ozone doses are applied. Even if ether is mixed with polar solvents like H 2 O or H 2 O 2 the H-bond formed with O-atom of ether is very very weak due to stearic repulsion of R-groups in ethers. Fulminates [silver fulminate, AgCNO, can form in the reaction mixture from the Tollens' test for . The main target users are workers and those responsible for occupational safety and health. 2 Names and Identifiers Expand this section. Peroxide, dimethyl.
