  • Patent number: 9238618
    Abstract: Processes for the production of polyols from sources such as dried distillers grains plus solubles (DDGS) make use of a two-stage reaction scheme. In the first stage, the proteinaceous starting material is reacted with an aminating agent, such as diethanolamine (DEOA), to generate amino-amides and amides. These products are then reacted with an alkoxylating agent, preferably a substituted or unsubstituted epoxide to yield polyols. These polyols may be further reacted with isocyanates to give low-cost rigid polyurethane foams. In alternate forms, lignin may be directly converted to polyols by reaction with an alkoxylating agent, optionally followed by reaction with an isocyanate to produce polyurethanes.

  • Patent number: 7977424
    Abstract: A soy-based polyol is mixed with an isocyanate and aggregate to produce a soy-based polyurethane having superior mechanical properties. The aggregate composition may be varied to obtain different mechanical properties, as can the amount of resin. The resin may be crosslinked using a low molecular weight polyol, such as glycerine, to also improve structural performance. A catalyst may be added to accelerate curing time without reducing structural performance.

  • Patent number: 6686435
    Abstract: A method for making natural oil-based polyols directly from vegetable or animal oil using a consecutive two-step process involving epoxidation and hydroxylation is provided. Specifically, this process comprises adding a peroxyacid to a natural oil wherein said natural oil and said peroxyacid react to form an epoxidized natural oil and adding said epoxidized natural oil to a mixture of an alcohol, water, and a fluoboric acid catalyst. The catalytic amount of fluoboric acid is less than about 0.5% by weight of the entire reaction mixture, and the amount of water is about 10 to 30% by weight of the entire mixture. The epoxidized natural oil undergoes hydroxylation and forms a natural oil-based polyol. The present invention further includes a method for making natural oil-based polyols from epoxidized oil by hydroylating the epoxidized oil in the presence of fluoboric acid, alcohol and water in the amounts discussed above.

  • Patent number: 6573354

A further embodiment of the present invention involves making a vegetable oil-based polyol using an epoxidized vegetable oil as the starting material. The epoxidized vegetable oil undergoes hydroxylation by the same process as outlined above. According to another aspect of the present invention, the vegetable oil-based polyol formed by the novel methods of this invention may be reacted with an isocyanate to form a polyurethane. Alternatively, a filler such as silica may be combined with the vegetable oil-based polyol before it is reacted with the isocyanate. These polyurethanes made from vegetable oil-based polyols may be used to form electroinsulating casting resins.
