(一)材料检验(NMP)DIN 51348(9,1991)苯及苯同系物检验;苯中噻吩含量的测定;气相色谱法上述标准为“气相色谱分析”NMP614工作委员会和“特殊汽油、试验用汽油及溶剂汽油的检验”NMP644工作委员会在 NMP的矿物油和燃料标准专业委员会(FAM)中共同制订的。本法用以测定苯中噻吩的含量。将含噻吩的试样先在极性分离柱分离其组分,然后借助柱转换技术,转换到第二分离柱,再导至火焰光度检测器(FPD)。以外标法测定并计算噻吩含量(mg/kg)。噻吩含量多少可说明苯的纯度,并与处理过程的操作技术有关。(二)化学术语(AchT)KDIN 32635(9,1991)溶液的光谱分析;概念,方程式表示,单位
(1) Material Testing (NMP) DIN 51348 (9, 1991) Testing of benzene and benzene homologues; Determination of thiophene in benzene; Gas chromatography The above standard is “Gas Chromatography” NMP614 Working Committee and “ Gasoline and Solvent Gasoline Testing ”The NMP644 Working Committee is co-developed with NMP’s FAM (Mineral Oil and Fuel Standards Board). This method is used to determine the content of thiophene in benzene. The thiophene-containing sample is first separated on a polar separation column and then converted to a second separation column by column conversion to a flame photometric detector (FPD). The external standard method for the determination and calculation of thiophene content (mg / kg). The amount of thiophene can explain the purity of benzene, and the operation of the process technology.
