Abstract

PURPOSE: To prepare a high purity SiCl4 in high efficiency, under relatively low temperature, by keeping a moving bed composed of specific three zones at a high temperature and feeding a mixture of an SiO2-containing material and carbon from the top and chlorine gas from the bottom of the bed, thereby reacting the SiO2 with chlorine.
CONSTITUTION: A moving bed composed of a top zone consisting of a mixture of an SiO2-containing material (e.g. quartzite) and carbon (e.g. active carbon), an intermediate zone consisting of a mixture of an SiO2-containing material, a boron compound (e.g. B2O3) and carbon, and the bottom zone consisting of carbon or a mixture of a boron compound and carbon, is kept at 300W1,200°C, pref. 400W 1,000°C. A mixture of an SiO2-containing material and carbon is fed to the moving bed from the top, and reacted with chlorine gas fed from the bottom. The reaction residue is discharged from the bottom of the reactor, and produced SiCl4 is recovered from the gas mixture discharged from the top of the reactor. A highly pure SiCl4 can be prepared by this process in high efficiency and yield, at a relatively low temperature.
