alkyl acyl derivatives, ions at [M -15]+ and [M - 90A1+. are 14 mass units less than those of the corresponding diacyl derivatives; (2) the base peak is m/e 130; (3) alkyl acyl derivatives show fragments due to one acyl group instead of the two acyl groups of diacyl derivatives; (4) ions at m/e 314 and 342, [R1O + 73]+., are characteristic of the trimethylsilyl derivatives of hexadecyl- and octadecylglycerols
通过气相色谱质谱仪系统分析了1-十六烷基-2-癸酰基-,-十六癸酰基-和-十八烯甘油甘油的三甲基甲硅烷基衍生物和1-十八烷基-2-癸酰基-,十六癸酰基和-十八烯酰基甘油以及1,2-二十六烷酰基甘油。以下几点是这些1-烷基-2-酰基衍生物的裂解模式的特征:(1)在烷基酰基衍生物,[M -15] +和[M-90A1 +]离子处。比相应的二酰基衍生物少14个质量单位;(2)基本峰值为m / e 130;(3)烷基酰基衍生物显示出由于一个酰基而不是二酰基衍生物的两个酰基而产生的片段;(4)m / e 314和342处的离子[R10 + 73] +。分别是十六烷基和十八烷基甘油的三甲基甲硅烷基衍生物的特征;(5)存在离子[M -R1O] +,
