摘要
以大口径PLOTAl2O3/KCl毛细管色谱柱为分离柱,采用气相色谱-质谱联用法(GC-MS)、自制的端基丁炔和标准样对聚合级丁二烯中碳氢化合物进行了分离,确定了丁二烯中的端基丁炔和二聚体。以端基丁炔标准气为外标,对丁二烯中的端基丁炔进行了定量分析,并采用面积归一化法对丁二烯中的其他杂质也进行了定量分析。
The hydrocarbons impurities in the commercial butadiene for polymeriz ing were sepa-rated effectively by PLOT Al 2 O 3 /KCl macropore column.The butynes,dimer and other impurities in the butadiene were determined by GC -MS andadding butyne prepared in laboratory and standard gases.The quantity of the butynes wa s measured by standard gas method and other impurities were quantified by area normalization.
