• Chromatographic grade ethers, which can contain peroxides (for example,
THF, dioxane, di-isopropylether) such ethers should be filtered through dry
aluminium oxide which adsorbs the peroxides.
• Solutions of organic acids (acetic acid, formic acid, and so on) in organic
solvents. For example, a 1-% solution of acetic acid in methanol will attack
steel.
• Solutions containing strong complexing agents (for example, EDTA,
ethylene diamine tetra-acetic acid).
• Mixtures of carbon tetrachloride with 2-propanol or THF.
