Determination of Heavy Substances in the Butanone Production Process by Gas Chromatography

A HP-5 capillary gas chromatography for the determination of heavy substances in the butanone producing process was presented. under the determined conditions,the components in the heavy substances were separated with good resolution and the separated components were identified by mass spectroscopy. The method is accurate and repeatable,The recoveriy of this method is between 98% and 102%.
