<p>The present invention relates to a manufacturing method of ethyl silicate. The manufacturing method may include the steps of: injecting, into a reactor, a mixture comprising silicon metal powder, potassium ethoxide, and ethyl silicate 40; stirring the mixture at 150-180°C at atmospheric pressure for 4-8 hours; synthesizing anhydrous ethanol with the mixture; transferring the synthesized ethyl silicate and non-reacted ethanol from the reactor to a condenser; storing the mixture condensed by the condenser in a storage tank and transferring the stored mixture to a distillation column; separating the ethyl silicate from ethanol through the distillation column; and accommodating the separated ethanol in storing means for reuse and accommodating the ethyl silicate in extracting means. The present invention does not have a catalyst process, which reduces the cost; and by using a fluid fluidized bed reactor, the ethyl silicate can be manufactured easily at atmospheric pressure and the time of contacting the metal becomes longer, increasing the yield.</p> |
