摘　　要：以苯基三甲氧基硅烷、四甲基二硅氧烷为原料,在固体酸催化下水解缩合,得到1,3-二苯基-1,1,3,3-四(二甲基硅氧基)二硅氧烷含量为42.6%的含氢低聚硅氧烷;再于0.665 kPa真空度下精馏,得到纯度为97.5%的产物。采用IR、GC-MS、1HNMR、13C NMR对其进行结构表征。结果表明,产物的结构特征与1,3-二苯基-1,1,3,3-四(二甲基硅氧基)二硅氧烷完全吻合。A kind of hydrogenous siloxane oligomers containing phenyl was synthesized by hydrolytic condensation between phenyltrimethoxysilane and tetramethyldisiloxane,in the presence of a solid acid catalyst,and the relative content of 1,3-diphenyl-1,1,3,3-tetrakis（dimethylsiloxy）disiloxane was 42.6%.Then it was rectified under the pressure of 0.665 kPa,and 1,3-diphenyl-1,1,3,3-tetrakis（dimethylsiloxy）disiloxane with a puirty up to 97.5%was obtained.The product was characterized by IR,GC-MS and NMR.Result showed that the structure of the target product matched that of 1,3-diphenyl-1,1,3,3-tetrakis（dimethylsiloxy）disiloxane perfectly.
