摘　　要：用低分辨电子轰击源质谱、高分辨精确质量测量质谱法研究了dl-2,3-二氰基-2,3-二(P-X取代苯基)丁二酸二乙酯(x=OCH_3、CH_3、H、Cl、NO_2)的质谱。讨论了这类化合物的质谱裂解机理及特征离子的结构。The mass spectra of five dl—diethyl 2,3—dicyano—2,3—di(P—X substituted phenyl) succinates (X=OCH_3,CH_3,H,ClandNO_2) were studied by means of low resolution EIMS and high resolution accuracy mass measuring MS. The fragmentation mechanism of the diethyl esters and structures of characteristic ions formed were discussed.
