摘要:Dissolved silanes, silicones and silicates from solvents used in the slurry phase Direct Synthesis of alkoxysilanes are removed by adding a carboxylic acid such as formic acid to generate filterable precipitates and reusable solvent. The solvents are thereby remediated and made suitable for reuse in Direct Synthesis processes. Foaming is reduced with the remediated solvent and silicon conversion rates are higher. The precipitates are easily filtered and retain negligible quantities of solvent.

摘要:The present disclosure provides a process for the selective synthesis of dimethyl carbonate 0 (DMC). More particularly, the present disclosure provides a process for inhibiting catalyst deactivation in a process for selective DMC synthesis. The process is particularly characterized by conducting the process in the presence of a small quantity of air. Further provided herein is a system for facilitating the said process. The process and the system (Figure 1) of the present disclosure prolong the life of the catalyst by virtue of introduction of air into the reactor.

摘要:The present disclosure provides a process for the continuous and selective synthesis of Dimethyl carbonate (DMC) addressing issues such as choking, reagent consumption and other downstream issues. The process of the present disclosure is characterized by integration of 2 reactions, one for the conversation of alcohol and carbon dioxide to DMC in the presence of a nitrile based dehydrating agent and the second for the re-generation of the nitrile based dehydrating agent in the presence of a suitable solvent. Further provided herein is a system (Figure 1) for facilitating the said process. The process is characterized by prolonged catalyst activity, efficient regeneration of reactants, low energy requirements and simple regeneration procedures.
