Paragraph 0023; 0024, (2017/01/02)
The invention relates to the field of organic chemistry. In order to solve dual problems of equipment loss and environmental pollution generated in synthesis of ethyl phenyl dimethoxysilane by virtue of an alcoholysis method, the invention provides ethyl phenyl dimethoxysilane and a preparation method thereof. Ethyl phenyl dimethoxysilane is prepared from ethyl trimethoxysilane and chlorobenzene as raw materials by virtue of a sodium condensation method. The reaction conditions are mild, no harms to the environment and equipment are caused and the process is simple and is very suitable for large-scale industrial production.

The saturated temperatures of ethylphenyldimethoxysilane (EPDMOS) and ethylphenyldiethoxysilane (EPDEOS) were determined using an inclined ebulliometer from 2.035 to 64.0 kPa. The experimental data were fitted with the Antoine and Clarke-Glew equations by a weighted least-squares regression method, which yielded Antoine parameters (A = 9.1280, B = 1590.18, C = minus100.39 K and A = 9.1049, B = 1678.64, C = minus102.84 K) and standard vaporization enthalpies (δlgHm0(298.15 K) = 62.52 kJ·mol-1 and δlgHm0(298.15 K) = 65.19 kJ·mol-1) for EPDMOS and EPDEOS, respectively. The critical properties of EPDMOS and EPDEOS, such as critical temperature, pressure, and volume, were estimated by the group contribution method introduced by Nannoolal et al. The acentric factors of EPDMOS and EPDEOS were estimated from these critical parameters and the reduced saturated vapor pressures calculated from either the Clarke-Glew equation or the Antoine equation.
