Summary:PURPOSE:To produce silicon hexachloride economically, in high operability, by reacting ferrosilicon with chlorine using a mixing horizontal reaction tube. CONSTITUTION:A mixing horizontal reaction tube 1 containing stirring blades and furnished with the heating jacket 5 is used in the present process. The ferrosilicon (having a silicon content of about 40-80wt% and an average particle diameter of about 50-1,000mu) is charged in the reaction tube 1, stirred with the stirring blades 2 (at about 5-100rpm), and made to react with chlorine gas supplied through the inlet 4 to the reactor at a rate of about 2-50l/hr per 1kg of ferrosilicon, at 120-220 deg.C. The gas flowing out of the reaction tube 1 is cooled to about 0 deg.C by the condenser 6, and the obtained liquid composed mainly of silicon hexachloride is collected in the reservoir 7.
