Abstract
The article describes a fundamentally new one-step chlorine free mechanochemical method for the direct synthesis of alkoxysilanes. The essence of the developed method consists in the direct interaction of untreated silicon with a dispersion up to 5 mm with an appropriate aliphatic alcohol containing from 1 to 4 carbon atoms in the presence of a copper-containing catalyst at a temperature of 200–300 °C in a vibrating fluidized bed of milling bodies in a wide vibration acceleration range. The experiments proved the principal possibility of its realization in a developed vibratory reactor, whose design solutions are adaptable to industrial application. It is shown that mechanoactivation plays a major role in the developed method of direct synthesis and is in fact the basis of a fundamentally new technological process.
