Patent abstract
In the preparation of phosphonatosilanes by reaction of organophosphites with halocarbon-functional silanes, the safety of the reaction is markedly increased while increasing space/time yield by continuously or periodically withdrawing reaction mixture, freeing the withdrawn mixture of phosphonatosilane product, and recycling the product-depleted remainder back to the reaction. Operation at temperatures of 100° C. or lower is made possible by this process.
