Abstract
This invention relates to a process for removing impurities contained in a teritary butyl alcohol feedstock. The process involves contacting the feedstock with an iron (II) compound such as iron (II) chloride, under an inert atmosphere at elevated pressures and temperatures for a time sufficient to reduce the peroxides to alcohols and oxidize the iron (II) to iron (III). The iron (II) compound is added in a homogeneous phase which, after reaction has occurred, gives a mixture of the treated teritary butyl alcohol, iron (III) compound and any residual iron (II) compound. The iron (III) and any iron (II) compounds are separated from the product by contacting the mixture with a cation exchange column.
