| titleOfInvention | Continuous production process of silicon tetrafluoride using various fluoride raw materials and amorphous silica and sulfuric acid |
| abstract | The present invention relates to a continuous method for producing silicon tetrafluoride (SiF 4 ) using various fluoride raw materials, amorphous silica (SiO 2 ) and sulfuric acid, and more particularly, to react with sulfuric acid to produce hydrogen fluoride (HF). After the reaction of the fluoride source material, amorphous silica and sulfuric acid, which generates), in a reactor, the obtained gaseous product is passed through a sulfuric acid scrubber (H 2 SO 4 Scrubber) to increase the yield of silicon tetrafluoride. By using various fluoride raw materials other than hydrogen fluoride, it is possible to continuously manufacture silicon tetrafluoride at low cost and environment-friendly, and to minimize the corrosion of the device by minimizing the hydrogen fluoride generated during the reaction, that is, hydrofluoric acid. the product is used and passed through a silicon fluoride (SiF 4) with the hot sulfuric acid scrubber (H 2 SO 4 scrubber) in a water gas mixture by removing water Yes A will to water and prevents the generation of SiF silica gel by the side reaction of 4 (Silica Gel) and rules hydrofluoric acid (H 2 SiF 6) relates to a process for the preparation of a tetrafluoride of silicon that can plug the pipe yield reduction in clogging or SiF 4 . |
