Corrosion data compilation generally shows little or no corrosion for metallic materials exposed to pure organic solvents. Yet in actual plant experience, many corrosion problems have occurred in organic solutions. This happens because it is rare in an operating chemical plant to have pure organic solvents. In many cases, the solvents contain low levels of contamination; for example, water and low levels of acids.

In addition, sometimes corrosive reactants or products are present. The presence of these chemicals can drastically change the noncorrosive characteristic of a pure solvent to one causing unacceptably high corrosion. The critical factors for assessing whether corrosion will be a problem in contaminated organic liquids are described and methods for controlling corrosion are outlined.
