摘　　要：采用带阀耐压钢管进行了标准样品的配制并利用气相色谱法采用Gaspro毛细管色谱柱,以2-氯-1,1,1,2-四氟丙烷(HCFC-244bb)为对照品,测定了2,3,3,3-四氟丙烯(HFO-1234yf)、2-氯-3,3,3-三氟丙烯(HCFO-1233xf)相对于2-氯-1,1,1,2-四氟丙烷(HFC-244bb)的质量校正因子。结果表明,不同浓度在一定范围内线性关系良好,相关系数(R2)均>0.99,为2,3,3,3-四氟丙烯合成过程相关中间体的定量分析提供了重要数据支持。The standard sample was prepared with steel tube and the relative mass calibration factors of 2,3,3,3-tetraflu- oropropene and its synthetical intermediate had been measured by GC with GS-gaspro column using 2-chloro-1,1,1,2- tetrafloropropane（HFC-244bb） as contrast. The results showed that different concentration proportion had good linearity in certain ranges with the correlation coefficients （R2） higher than 0.99, providing important data sustain for quantitative analysis of 2,3,3,3-tetrafluoropropene and its synthetical intermediate.
