  • Epdxidized fatty acid alkyl ester plasticizers and methods for making epdxidized fatty acid alkyl ester plasticizers
    Patent number: 9850366
    Abstract: Epoxidized fatty acid alkyl ester and methods for making epoxidized fatty acid alkyl ester. The epoxidized fatty acid alkyl ester is prepared from a fatty acid alkyl ester starting material comprising at least one of mono-unsaturated and di-unsaturated fatty acid alkyl ester molecules in a combined amount of at least 85 weight percent. Such epoxidized fatty acid alkyl esters can be employed in plasticizer compositions, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.
    Type: Grant
    Filed: October 18, 2012
    Date of Patent: December 26, 2017
    Assignee: Dow Global Technologies LLC
    Inventors: Neeta Rao, Saurabh Kaujalgikar, Bharat I. Chaudhary, Shreyas Bhide, Shantaram Morye, Sachin Agashe
  • Methods for making epoxidized fatty acid alkyl esters
    Patent number: 9593091
    Abstract: Methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing a natural oil with an acid and a peroxide. Residual acid in the epoxidized natural oil is not neutralized, such as with a base, prior to esterification to produce the epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizers, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.
