Disproportionation reaction of SIHCL3
Thread Content
The equation for the disproportionation reaction of SIHCL3 and whether it is exothermic or endothermic! The usage of catalysts, as well as the equipment – what type of tower is used? I would appreciate it if you could share your insights!
2SiHCl3=SiCl4+SiH2Cl2-Q 2SiH2Cl2=SiH4+SiCl4-Q Friend, do you want to produce silanes? There is no need to use trichlorosilane; inexpensive silicon tetrachloride can be used instead. SiCl4 + Al + 6H2 = 4AlCl3 + 3SiH4; temperature is 175 degrees, and the pressure is very high ； Alternatively, reacting SiCl4 with **aluminum lithium yields better results, though** aluminum lithium is more expensive.
Does anyone else know the conditions for the disproportionation of trichlorosilane? And the conditions for the formation of silanes from dichlorodihydrosilicon?
The equipment is quite simple; it’s just a regular fixed-bed reactor, similar to a tube heat exchanger. SiCl4 + SiH2Cl2 = 2SiHCl3. At a certain molar ratio and at room temperature, the catalyst is the key factor; it seems that this catalyst is not produced in China currently and is imported from the United States
Hey, why is everything nowadays about restoration and distillation? What about CDI?
Replace the catalyst once a year; it’s really expensive. I wouldn’t have used it if it weren’t to get rid of dichlorodihydrosilicon
