Rapid determination of DNBP in styrene by gas chromatography with HP-5 column
DNBP(2-sec-butyl-4,6-dinitrophenol)in styrene was separated by HP-5 column,detected by FID and quantified by external standard method[1],and the content of DNBP in styrene was rapidly determined.The experimental results showed that this method had good accuracy and precision,short analysis time,met the requirements of method standard[2]and process control,and could successfully replace the traditional spectrophotometry.
