  • Apparatus and method for the condensed phase production of trisilylamine
    Patent number: 9701540
    Abstract: The present invention is directed to a condensed phase batch process for synthesis of trisilylamine (TSA). An improved synthesis method that incorporates a solvent to help promote a condensed-phase reaction between ammonia gas (or liquid) and liquified monochlorosilane (MCS) in good yields is described. This method facilitates the removal of the byproduct waste with little to no reactor down time, substantial reduction of down-stream solids contamination and high-purity product from first-pass distillation.

    Abstract: A method is provided for synthesizing silicon-germanium hydride compounds of the formula (H3Ge)4-xSiHx, wherein x=0, 1, 2 or 3. The method includes combining a silane triflate with a compound having a GeH3 ligand under conditions whereby the silicon-germanium hydride is formed. The compound having the GeH3 ligand is selected from the group consisting of KGeH3, NaGeH3 and MR3GeH3, wherein M is a Group IV element and R is an organic ligand. The silane triflate can be HxSi(OSO2CF3)4-x or HxSi(OSO2C4F9)4-x. The method can be used to synthesize trisilane, (H3Si)2SiH2, and the iso-tetrasilane analog, (H3Si)3SiH, by combining a silane triflate with a compound comprising a SiH3 ligand under conditions whereby the silicon hydride is formed. The silane triflate can include HxSi(OSO2CF3)4-x or HxSi(OSO2C4F9)4-x wherein x=1 or 2. A method for synthesizing (H3Ge)2SiH2 includes combining H3GeSiH2(OSO2CF3) with KGeH3 under conditions whereby (H3Ge)2SiH2 is formed.
