  • 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: 8692030
    Abstract: A method of making a biobased-petrochemical hybrid polyol is provided. This method includes reacting a cyclic ether with a vegetable oil-based polyol in the presence of a cationic catalyst or a coordinative catalyst that includes a vegetable oil-based polyol ligand to form the biobased-petrochemical hybrid polyol. The biobased-petrochemical hybrid polyol that is created has a number average molecular weight of about 3,000 to about 6,000 and has a structure that is about 22% to about 36% biobased. In one aspect of the present invention, the cyclic ether is propylene oxide, and the propoxylated polyol formed from the propylene oxide and vegetable oil-based polyol is then reacted with ethylene oxide in the presence of a superacid catalyst to create a block copolymer with a terminal polyethylene oxide block having a high percentage of terminal primary hydroxyl groups.
