Abstract

Prosess for å produsere silisiumtetraklorid, SiCl4, ved reaksjon mellom silisium metall, Si, og klor, Cl2, i en reaktor. Temperaturen og reaksjonshastigheten kontrolleres ved samtidig direkte innsprøyting av klor og et kjølemedium i reaksjonssonen til en reaktor. Kjølemediet kan fortrinnsvis være silisiumtetraklorid eller en inert gass.Process for producing silicon tetrachloride, SiCl4, by reaction of silicon metal, Si, and chlorine, Cl2, in a reactor. The temperature and reaction rate are controlled by simultaneous direct injection of chlorine and a refrigerant into the reaction zone of a reactor. The refrigerant may preferably be silicon tetrachloride or an inert gas.
