Gas chromatographic determination of water in organic compounds and of organic compounds in water after steam distillations
A gas chromatograph (GC) with a flame ionization detector (FID) is shown to be effective in the determination of water in organic compounds. Since the FID gives little response for water, a reaction is needed to convert water into a detectable species. The ketal, 2,2-dimethoxypropane (DMP), reacts quantitatively with water to yield the products methanol and acetone when an acid catalyst is present. Acetone is easily determined with a GC equipped with a capillary column and FID. A solid acid catalyst, Nafion, has been effective and is easily separated before sample introduction into the GC.
