ABSTRACT:
This invention relates to acetonitrile purification via an adsorption-based process. The process comprises pretreating the acetonitrile containing organic impurities such as unsaturated nitriles with a solid reagent to selectively convert the unsaturated nitriles into products more easily removed and passing the treated acetonitrile through a series of adsorbent beds to remove the resulting products and other impurities present from the acetonitrile.
