1,3,5-三甲基-1,1,3,5,5-五苯基三硅氧烷(1)含有较多苯基,其沸点较高(225℃/0.2mm),饱和蒸汽压低,热稳定性和抗氧化性能良好,可作为理想的高真空扩散泵油.
1,3,5,-Trimethyl-1,1,3,5,5-pentaphenyltrisiloga,ne has been prepared by the equilibration of 1,3-dimethyl-1,1,3,3,-tetraphenyldisilosane and methylptienyloy-closiloaanes in the presence of tetramethyl ammonimn silanolate.By the repeated recycling of the by-products siloxanes,it wag possible to obtain an overall yield of over 90%.The physical properties and the oxidative stability of 1,3,5-trimethyl 1,1,3,5,5-pentaphenyltrisiloxane were also determined.
