These are condensed at -196°C degrees and fractionally distilled at temperatures up to -78°C. SiClF3 can be made by reacting silicon tetrachloride and silicon tetrafluoride gases at 600°C, producing a mixture of fluorochloro silanes including about one quarter SiClF3.〔 〕 SiClF3 can be made by reacting silicon tetrachloride with antimony trifluoride. An antimony pentachloride catalyst assists. The products are distilled to separate it out from tetrafluorosilane and dichlorodifluorosilane.〔 At high temperatures above 500°C silicon tetrafluoride can react with phosphorus trichloride to yield some SiClF3. This is unusual because SiF4 is very stable. Silicon tetrachloride can react with trifluoro(trichloromethyl)silane to yield SiClF3 and CCl3SiCl3. 2-Chloroethyltrifluorosilane or 1,2-dichloroethyltrifluorosilane can be disassociated by an infrared laser to yield SiClF3 and C2H4 (ethylene) or vinyl chloride. By tuning the laser to a vibration frequency of a particular isotope of silicon, different isotomers can be selectively broken up in order to have a product that only concentrates one isotope of silicon. So silicon-30 can be increased to 80% by using the 934.5 cm−1 line in a CO2 laser. The first published preparation of SiClF3 by Schumb and Gamble was by exploding hexafluorodisilane in chlorine: Si2F6 + Cl2 → 2SiClF3. Other products of this explosion may include amorphous silicon, SiCl2F2 and SiF4. Chlorine reacts with silicon tetrafluoride in the presence of aluminium chips at 500-600°C to make mostly silicon tetra chloride and some SiClF3. Mercuric chloride when heated with SiF3Co(CO)4 breaks the bond to form a 90% yield of SiClF3. The combination of SiF4 and dimethylchlorophosphine and yield some SiClF3. Trifluorosilane SiHF3 reacts with gaseous chlorine to yield SiClF3 and HCl. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chlorotrifluorosilane」の詳細全文を読む スポンサード リンク
