Abstract
An improved process for preparing N-triorganosilylcarbamide acid esters by reacting in the substantial absence of a solvent a carbamide acid ester having two hydrogen atoms linked to the nitrogen atom with a hexaorganodisilazane and a triorganohalosilane and thereafter separating the resultant N-triorganosilylcarbamide acid ester from ammonium halide.

A process for preparing N-triorganosilylcarbamide acid esters which comprises reacting in the substantial absence of a solvent a carbamide acid ester having two hydrogen atoms linked to its nitrogen atom with a hexaorganodisilazane and a triorganohalosilane at a temperature of from 20.degree. to 65.degree. C. and thereafter separating the thus formed N-triorganosilylcarbamide acid ester from ammonium halide by-product.
