1,1,3,5,5-五甲基-3-苯基三硅氧烷 (PTMP)、3-(二甲基硅氧基)-1,1,5,5-四甲基-3-苯基三硅氧烷 (DMTMP) 和 1,1 的饱和温度,5,5-四甲基-3,3-二苯基三硅氧烷（TMDP）在3.000至58.000 kPa的不同压力下获得。PTMP、DMTMP 和 TMDP 的密度和粘度在 293.15 至 328.15 K 的不同温度下测定。通过使用线性方程，密度数据具有良好的相关性。粘度值通过 Andrade、Ghatee、Litovitz 和 Vogel-Fulcher-Tammann (VFT) 方程计算。这些化合物的饱和蒸气压作为饱和温度的函数与 Clarke-Glew 和 Antoine 方程密切相关。Nannoolal 模型用于通过基团贡献法估计临界压力、温度和体积特性。临界参数用于估计 PTMP、DMTMP 和 TMDP 在降低的饱和蒸气压下的偏心因子 (ω)，该偏心因子通过 Clarke-Glew 或 Antoine 方程计算。PTMP、DMTMP 和 TMDP 的回归 VLE 方程参数、摩尔蒸发焓和 ω 值是工业分离过程的重要数据。

Density, Viscosity, and Vapor Pressure of 1,1,3,5,5-Pentamethyl-3-phenyltrisiloxane, 3-(Dimethylsilyloxy)-1,1,5,5-tetramethyl-3-phenyltrisiloxane, and 1,1,5,5-Tetramethyl-3,3-diphenyltrisiloxane

The saturation temperatures of 1,1,3,5,5-pentamethyl-3-phenyltrisiloxane (PTMP), 3-(dimethylsilyloxy)-1,1,5,5-tetramethyl-3-phenyltrisiloxane (DMTMP), and 1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane (TMDP) were obtained at different pressures ranging from 3.000 to 58.000 kPa. The density and viscosity of PTMP, DMTMP, and TMDP were determined at different temperatures ranging from 293.15 to 328.15 K. The density data were well correlated by using a linear equation. The viscosity values were calculated with the Andrade, Ghatee, Litovitz, and Vogel–Fulcher–Tammann (VFT) equations. The saturated vapor pressure of these compounds as a function of saturated temperature was well correlated with both the Clarke–Glew and Antoine equations. The Nannoolal model was used to estimate the critical pressure, temperature, and volume properties via the group contribution method. The critical parameters were used to estimate the acentric factor (ω) of PTMP, DMTMP, and TMDP at a reduced saturated vapor pressure that was calculated from either the Clarke–Glew or Antoine equations. The values of the regressed VLE equation parameters, molar evaporation enthalpies, and ω of PTMP, DMTMP, and TMDP are essential data for industrial separation processes.
