  • Organometallic compound preparation
    Patent number: 9403145
    Abstract: An apparatus for continuously manufacturing organometallic compounds is provided where the apparatus has a source of a first reactant stream wherein the first reactant comprises a metal; a source of a second reactant stream; a laminar flow contacting zone for cocurrently contacting the first reactant stream and the second reactant stream; a mixing zone comprising a turbulence-promoting device; and a heat transfer zone.
    Type: Grant
    Filed: March 9, 2015
    Date of Patent: August 2, 2016
    Assignees: Dow Global Technologies LLC, Rohm and Haas Electronic Materials LLC
    Inventors: Ravindra S. Dixit, Hua Bai, Curtis D. Modtland, Robert A. Ware, John G. Pendergast, Jr., Christopher P. Christenson, Deodatta Vinayak Shenai-Khatkhate, Artashes Amamchyan, Kenneth M. Crouch, Robert F. Polcari
  • Organometallic compound purification
    Patent number: 9085594
    Abstract: A method of purifying crude organometallic compounds using a plurality of distillation columns is provided. This method effectively removes both relatively more volatile impurities and relatively less volatile impurities as compared to the organometallic compound.
