Discussion on GC analysis of commercial sec-butylamine samples

The basic characteristics of GC analysis sec-butylamine product synthesized from sec-butylalcohol by cobalt-catalytic ammoniation under the condition of hydrogen are studied.The analytical methods for sec-butylamine using new-type mixed quartz capillary columns in industrial production are discussed.The results indicate that sec-butylamine has good separation degree and linear correlation on new-tape mixed quartz capillary columns.The relative standard deviation is in the range of 0.2% with good repeatability.The method can be operated rapidly and fulfilled within 7 minutes with quick speed and strong practical applicability.
