  • Organometallic compound purification
    Patent number: 7321048
    Abstract: A method of purifying an organometallic compound by heating the organometallic compound in the presence of a trialkyl aluminum compound and a catalyst.
    Type: Grant
    Filed: November 17, 2006
    Date of Patent: January 22, 2008
    Assignee: Rohm and Haas Electronic Materials LLC
    Inventors: Deodatta Vinayak Shenai-Khatkhate, Ronald L. DiCarlo, Jr.
  • Alkyl group VA metal compounds
    Patent number: 6956127
    Abstract: Disclosed are methods of preparing monoalkyl Group VA metal dihalide compounds in high yield and high purity by the reaction of a Group VA metal trihalide with an organo lithium reagent or a compound of the formula RnM1X3?n, where R is an alkyl, M1 is a Group IIIA metal, X is a halogen and n is an integer fro 1 to 3. Such monoalkyl Group VA metal dihalide compounds are substantially free of oxygenated impurities, ethereal solvents and metallic impurities. Monoalkyl Group VA metal dihydride compounds can be easily produced in high yield and high purity by reducing such monoalkyl Group VA metal dihalide compounds.

    Date of Patent: October 18, 2005
    Assignee: Shipley Company, L.L.C.
    Inventors: Deodatta Vinayak Shenai-Khatkhate, Michael Brendan Power, Artashes Amamchyan, Ronald L. DiCarlo, Jr.
  • Trialkylindium preparation
    Patent number: 6770769
    Abstract: Trialkylindium compounds are prepared by reacting indium trihalide with a trialkylaluminum compound in the presence of a fluoride salt, wherein the molar ratio of the indium trihalide to the fluoride salt is at least 1:4.5. Such trialkylindium compounds are particularly suitable for use in metalorganic vapor phase epitaxy.
    Type: Grant
