| Introduction | Dichlorosilane, abbreviated as DCS, is an inorganic compound with the chemical formula H2SiCl2. |
| Properties | Dichlorosilane is hydrolyzed in water to produce polysiloxane (-H2Si-O-)n; and ammonia reacts ammonolysis to produce (-H2SiNH-)n[2]. |
| use | dichlorosilane can be used as the starting material of the semiconductor silicon layer in microelectronics. its advantage is that it can be decomposed at a lower temperature and has a higher silicon crystal growth rate. As a pharmaceutical intermediate. |
| Preparation | Dichlorosilane can be prepared by reacting silane and hydrogen chloride in the presence of aluminum trichloride catalyst in a stoichiometric ratio: it can also be prepared by trichlorosilane: 2 SiHCl3 SiH2Cl2 SiCl4 |
| Production method | It is obtained from chlorination of decanediol by thionyl chloride. Put decanediol and pyridine into the reaction pot, and add thionyl chloride dropwise under cooling. After adding, stir and react at room temperature for 3h, then reflux for 3h. Excess thionyl chloride was recovered and then distilled under reduced pressure to collect the 126-127°C (0.93kPa) fraction to obtain dichlorodecane. The yield was 88%. |
