Abstract The saturated temperature of ethenyltris(2,2,2-trifluoroethoxy)silane (trisF-ES), dimethoxymethyl(3,3,3-trifluoropropyl)silane (F-DiMOMS) and trimethoxy(3,3,3-trifluoropropyl)silane (F-TriMOS) were determined using an inclined ebulliometer from 3.00 to 100.00 kPa. The experimental data were fitted with the Antoine equation and the Clarke−Glew equation by a weighted least-squares regression method, and gave the Antoine parameters (A = 8.8461, B = 1207.11, C = −114.06 K, A = 8.8040, B = 1166.06, C = −97.69 K and A = 8.9712, B = 1279.86, C = −92.77 K) and standard vaporization enthalpy Δ l g H m 0 (298.15 K) = 55.84 kJ mol−1, Δ l g H m 0 (298.15 K) = 47.54 kJ mol−1 and Δ l g H m 0 (298.15 K) = 49.48 kJ mol−1 for trisF-ES, F-DiMOMS and F-TriMOS, respectively. The critical properties of trisF-ES, F-DiMOMS and F-TriMOS, including critical temperature, pressure, and volume, were estimated by the group contribution method introduced by Nannoolal et al. The acentric factors (ω) of trisF-ES, F-DiMOMS and F-TriMOS were estimated from these critical parameters and the reduced saturated vapor pressures calculated using both the Antoine equation and the Clarke−Glew equation.

乙烯基三(2,2,2-三氟乙氧基)硅烷、二甲氧基甲基(3,3,3-三氟丙基)硅烷和三甲氧基(3,3,3-三氟丙基)硅烷饱和​​蒸气压的测量和相关性

摘要 乙烯基三(2,2,2-三氟乙氧基)硅烷(trisF-ES)、二甲氧基甲基(3,3,3-三氟丙基)硅烷(F-DiMOMS)和三甲氧基(3,3,3-三氟丙基)硅烷的饱和温度(F-TriMOS) 是使用 3.00 至 100.00 kPa 的倾斜沸腾计测定的。实验数据通过加权最小二乘回归法拟合Antoine方程和Clarke-Glew方程,得到Antoine参数(A=8.8461,B=1207.11,C=-114.06K,A=8.8040,B= 1166.06, C = -97.69 K 和 A = 8.9712, B = 1279.86, C = -92.77 K) 和标准汽化焓 Δ lg H m 0 (298.15 K) = 55.84 kJ mol-1, Δ 2 lg H m.15 K ) = 47.54 kJ mol-1 和 Δ lg H m 0 (298.15 K) = 49.48 kJ mol-1 对于 trisF-ES、F-DiMOMS 和 F-TriMOS。trisF-ES、F-DiMOMS 和 F-TriMOS 的关键特性,包括临界温度、压力和体积,由 Nannoolal 等人引入的群贡献法估计。trisF-ES、F-DiMOMS 和 F-TriMOS 的偏心因子 (ω) 是根据这些关键参数和使用 Antoine 方程和 Clarke-Glew 方程计算的降低的饱和蒸气压估算的。
