  • Hydroxyl containing quaternary ammonium salts of fatty acids as internal mold release compositions
    Patent number: 5317075
    Abstract: In an active hydrogen-containing B-side composition for reaction with a polyisocyanate-containing A-side composition to make a polyurethane or polyurethane/urea elastomer by reaction injected molding, the improvement which comprises a mold release composition which is the reaction product of a C.sub.12 -C.sub.36 fatty acid, a tertiary amine having at least one C.sub.12 -C.sub.18 alkyl substituent and a C.sub.2 -C.sub.21 reactive epoxide.
    Type: Grant
    Filed: December 16, 1992
    Date of Patent: May 31, 1994
    Assignee: Air Products and Chemicals, Inc.
    Inventors: John E. Dewhurst, Ronald M. Pearlstein, Thomas W. Panunto, Reinaldo M. Machado
  • Process for modifying the glycolysis reaction product of polyurethane scrap
    Patent number: 5300530
    Abstract: A process for converting polyurethane foam into reusable polyol composition which comprises glycolyzing the polyurethane foam to yield a glycolysis polyol product containing amines and reacting the glycolysis polyol product with an alkylene oxide in a mole ratio of <1 mole of alkylene oxide per mole of active amine hydrogen atom in the glycolysis polyol product.
    Type: Grant
    Filed: December 11, 1992
    Date of Patent: April 5, 1994
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Reinaldo M. Machado, Brian E. Farrell
  • Preparation of urethane prepolymers having low levels of residual toluene diisocyanate
    Patent number: 5202001
    Abstract: A wiped film evaporation process for reducing the amount of residual organic polyisocyanate, especially toluene diisocyanate, in a polyurethane prepolymer reaction product mixture. An inert sweeping gas is added to the evaporation process, preferably after first passing through a holdup volume of the prepolymer which has passed through the evaporation zone.
    Type: Grant
    Filed: July 9, 1991
    Date of Patent: April 13, 1993
    Assignee: Air Products and Chemicals, Inc.
    Inventors: William E. Starner, Bernard A. Toseland, Reinaldo M. Machado
  • Preparation of aliphatic dihydroperoxides
    Patent number: 5149883
    Abstract: This invention relates to an improved process for preparing dihydroperoxyalkanes and, particularly, dimethyldihydroperoxyhexane. The improvement resides in utilizing a tetrahydrofuran derivative which is a liquid as a feedstock. This feedstock then is reacted with hydrogen peroxide in the presence of sulfuric acid to form the dihydroperoxide.
