Patent number: 8669387Abstract: There is described a process for preparing silylamines in and particularly trisilylamine (TSA) in high yields in a tubular laminar flow, plug flow reactor, from ammonia gas and a monohalosilane gas. The apparatus can be a tubular flow reactor comprising a first portion of the reactor defining a gas entry zone, a second portion of the reactor defining a reaction zone and a third portion of the reactor defining a separation zone, the reaction zone providing a reactant contacting region. Trisilylamine can be recovered in the separation zone in a cold trap collection vessel.Type: GrantFiled: March 19, 2013Date of Patent: March 11, 2014Assignee: Voltaix, Inc.Inventor: Gary D. Miller

Patent number: 8568682Abstract: 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.Type: GrantFiled: October 4, 2012Date of Patent: October 29, 2013Assignee: Voltaix, Inc.Inventor: Cole J. Ritter, III

Patent number: 7666379Abstract: A process and apparatus is provided for the purification of binary halide fluid. The process and apparatus purifies the binary halide fluid by selectively removing Bronsted acid impurities and/or volatile oxygen containing impurities present in the binary halide. A regenerable adsorbent polymer is utilized to remove the Bronsted acid impurities from the binary halide fluid and a volatile oxide adsorbent having a specific adsorption capacity for the volatile oxide impurity is utilized to remove the volatile oxide from the binary halide when in gaseous form.Type: GrantFiled: December 2, 2005Date of Patent: February 23, 2010Assignee: Voltaix, Inc.Inventors: Leisl Dukhedin-Lalla, German Shekk, John P. de Neufville, Michael Pikulin
