  • Polyols from epoxidized tallow trimethylolpropane and propylene oxide
    Patent number: 4124609
    Abstract: Polyols suitable for use in urethane foams are made by a three-stage process that is much less dependent on petroleum-based chemicals than are prior art methods and that eliminates washing unreacted reagents out of the product. Trimethylolpropane is first reacted under acid catalysts with epoxidized tallow, the reacted epoxidized tallow is then reacted under alkaline catalysis with trimethylolpropane, and the resilient product reacted with propylene oxide.
