• 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.
