摘要：

Fifteen specimens of tetraalkoxysilanes were prepared and their tentative tetrahedral structures proposed. Ultrasonic velocities were measured over the temperature range of 30-80 degree C using a multifrequency ultrasonic interferometer. Molar sound velocity, molar compressibility, adiabatic and isothermal compressibilities and intermolecular free length were evaluated using the experimentally determined ultrasonic velocity, density, specific heat and molecular weight. Some of these properties are compared with corresponding properties of polydimethylsiloxanes.
