摘要
The article is the analysis of phenyl isocyanate in benzene by gas chromatography.Inspection column temperature、detector temperature and boil room temperature at the effect on the determination,determined the optimal conditions for gas chromatographic analysis:column temperature:180℃,detector temperature:250℃,boil room temperature:260 ℃.Under these conditions,the standard deviation are 0.10mg/L,the relative standard deviation were 0.48%,recoveries were more than 99.4%,achieved satisfactory results.Provides an analytic method of phenyl isocyanate in benzene.
