  • Patent number: 6392092
    Abstract: A method for manufacturing 3-hydroxy-3-methylbutanoic acid (HMB) in commercially viable amounts is disclosed. The reaction mixture cycles through an external heat exchanger while the primary reactant is added in a warmer so as to control and maintain a low temperature for the reaction mixture. The manufacturing process herein disclosed increases yield while decreasing reaction time from the synthetic processes currently practiced.
    Type: Grant
    Filed: April 17, 2001
    Date of Patent: May 21, 2002
    Assignee: Met-Rx USA, Inc.
    Inventors: Lawrence W. McCoy, Daniel A. Lima, Melvin E. Miller

  • Patent number: 4141913
    Abstract: A method of generating lower alkyl and cycloalkyl isocyanates in situ by pyrolysis of an appropriately selected alkyl aryl urea of the formula ##STR1## where R.sub.1 aryl, R.sub.2 may be either alkyl, cycloalkyl or aryl, and in which R.sub.3 is the specific lower (C.sub.1 through C.sub.6) alkyl or cycloalkyl radical of the isocyanate selected to be generated.
