  • Natural oil-derived polyester polyols and polyurethanes made therefrom
    Patent number: 8664352
    Abstract: A polyester polyol made from natural oil feedstocks is disclosed. Methods for making the polyol are also disclosed. The method comprises reacting hydroxylated fatty acid/alkyl esters with a multifunctional ester-reactive initiator compound to form the polyester polyol. In one embodiment, the hydroxylated fatty acid/alkyl esters are made by hydroxylating fatty acid/alkyl esters having up to ninety-five percent by weight monounsaturation.
    Type: Grant
    Filed: October 31, 2008
    Date of Patent: March 4, 2014
    Assignee: Cargill, Incorporated
    Inventors: Timothy Walter Abraham, Jeff J. Malsam

  • NATURAL OIL-DERIVED POLYESTER POLYOLS AND POLYURETHANES MADE THEREFROM
    Publication number: 20100240860
    Abstract: A polyester polyol made from natural oil feedstocks is disclosed. Methods for making the polyol are also disclosed. The method comprises reacting monohydroxylated fatty acid/alkyl esters with a multifunctional ester-reactive initiator compound to form the polyester polyol. In one embodiment, the monohydroxylated fatty acid/alkyl esters are made by hydroxylating fatty acid/alkyl esters having greater than about ninety-five percent by weight monounsaturation.

  • Continuous process for preparing lactic acid
    Patent number: 6509179
    Abstract: The invention relates to a continuous process for preparing lactic acid, comprising: (a) acidifying an aqueous feed, which has been obtained by fermentation and mainly contains lactate, with a stream containing inorganic acid to a pH of from 1 to 4 to form an aqueous stream which mainly consists of lactic acid and a salt, (b) removing the salt from the aqueous stream which mainly contains lactic acid and salt to form a first aqueous stream which mainly contains lactic acid, (c) passing the first aqueous stream which mainly contains lactic acid over a column containing activated carbon to form a second aqueous stream which mainly contains lactic acid, (d) subjecting the second aqueous stream which mainly contains lactic acid to a first extraction step, wherein the second aqueous stream which mainly contains lactic acid is brought into contact with a substantially water-insoluble stream which contains an extractant, to form an organic phase which mainly contains lactic acid and extractant and a first water
