Organosilicon compounds or products, including alkoxysilanes [HSi(OR)₃, Si(OR)₄, RSiH(OR)₂, and RSi(OR)₃, where R is methyl (CH₃) or ethyl (C₂H₅)], organohydrosilanes [e.g., CH₃SiHCl₂, (CH₃)₂SiHCl, and CH₃SiCl₃], organosilicon alcohol [(CH₃)₃SiOH], and organoacyloxysilane [CH₃Si(OCOCH₃)₃], have been extensively studied and developed in recent years. Understanding the basic thermodynamics of the synthetic processes of these organosilicon compounds is necessary to optimize the associated reaction conditions and catalyst development, if any. Therefore, we have conducted a comprehensive study of the thermodynamics of organosilicon-related reactions using the Gibbs energy minimization method. The study evaluates the effects of reaction conditions, such as temperature, pressure, and reactant ratios, on the reactant conversion and product selectivity. The results show that the optimum thermodynamic conditions for the preparation of alkoxysilanes were low temperature, atmospheric pressure, and stoichiometric feed ratio. Meanwhile, other organosilicon compounds favor high temperatures and atmospheric pressure. The research proposes the optimum operating conditions for each reaction and provides a comprehensive reference for the thermodynamics of organosilicon synthesis reactions.
