Process for the Preparation of Organosilicon Compounds by Hydrosilylation in Ionic Liquids

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a method for producing silicon-organic compounds (silanes) via hydrosilylation, using a transition metal complex (such as platinum, iridium, or rhodium complexes) as a catalyst dissolved in an ionic liquid during the reaction. This enables a more selective, efficient, and recyclable catalysis process, where the ionic liquid facilitates easy separation and reuse of the catalyst, enhancing both the yield and purity of the desired silane products.

Use CasesContent extracted from patent full text and abstract with AI.

• Manufacturing of organosilanes for use in silicone polymer production.
• Production of silane-based adhesion promoters for coatings, adhesives, and sealants.
• Synthesis of hydrophobic agents and building protection materials.
• Customized synthesis of functionalized silanes for specialty chemicals in pharmaceuticals and agrochemicals.
• Continuous or batch silane manufacturing with improved catalyst recycling for industrial chemical plants.

BenefitsContent extracted from patent full text and abstract with AI.

• Higher selectivity and yield for desired silane products compared to traditional methods.
• Efficient separation and recycling of expensive metal catalysts, reducing costs and waste.
• Reduced by-product formation, leading to purer products and less downstream purification.
• Enablement of continuous processing with phase separation, improving process scalability and economics.
• Greater compatibility with functionalized olefins, broadening the scope of applicable reactants.
• Technical feasibility demonstrated for multiple reaction cycles with minimal activity loss, increasing sustainability.
