  • Patent number: 9446954
    Abstract: The invention relates to a process for preparing trisilylamine and polysilazanes in the liquid phase, in which ammonia is introduced in a superstoichiometric amount relative to 5 monochlorosilane which is present in an inert solvent. Here, a reaction in which trisilylamine and polysilazanes are formed proceeds. TSA is subsequently separated off in gaseous form from the product mixture. The TSA obtained is purified by filtration and distillation and obtained in high or very high purity. The bottom product mixture is conveyed from the reactor through a filter unit in which solid ammonium chloride is separated off to give a liquid mixture of polysilazanes and solvent. This is fed to a further distillation to recover solvent. As a result of the NH3 being introduced in a superstoichiometric amount relative to monochlorosilane, monochlorosilane is completely reacted in the reactor.

  • Publication number: 20150147256
    Abstract: The invention relates to a process for preparing trisilylamine and polysilazanes in the liquid phase, in which ammonia dissolved in an inert solvent is initially introduced in a substoichiometric amount relative to monochlorosilane which is likewise present in an inert solvent. The reaction is carried out in a reactor in which trisilylamine formed according to the following equation 4NH3+3H3SiCl?3NH4Cl+(SiH3)3N and polysilazanes are formed. The reactor is subsequently depressurized and TSA is separated off in gaseous form from the product mixture. The TSA obtained is purified by filtration and distillation and obtained in high or very high purity. Further ammonia dissolved in an inert solvent is subsequently introduced into the reactor, using, together with the previously introduced amount of ammonia, a stoichiometric excess of ammonia relative to the amount of MCS previously present.
