Analysis of diphenylsilanediol oligomers by HPLC-MS/MS(二苯基硅二醇低聚物的液相色谱-质谱分析)
采用三重串联四级杆液质联用仪(HPLC-MS/MS)对二苯基硅二醇缩合得到的低聚物进行分析,优化了色谱条件,组分分离效果良好.对质谱碎片离子进行解析,产物为二苯基硅二醇、1,1,3,3-四苯基-1,3-二硅氧烷二醇(二聚体)、1,1,3,3,5,5-六苯基-1,5-三硅氧烷二醇(三聚体)、1,1,3,3,5,5,7,7-八苯基-1,7-四硅氧烷二醇(四聚体)的混合物.2种催化条件下得到的产物组分相同,但主成分不同,盐酸催化下主要得到二聚体,钛酸正丁酯催化下主要得到三聚体和四聚体....
