  • 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

  • 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.

  • Patent number: 9499681
    Abstract: Epoxidized fatty acid alkyl esters and methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing fatty acid alkyl esters with an acid and a peroxide. Epoxidation can be performed under controlled reaction conditions to provide epoxidized fatty acid alkyl esters having an iodine value in the range of from 4 to 15 g I2/100 g of epoxidized fatty acid alkyl esters. 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.

  • Publication number: 20130289291
    Abstract: A process to prepare an estolide derivative composition comprises reacting a triglyceride having an unsaturation level of less than 0.1 m Eq/g and an alcohol having from 2 to 22 carbon atoms, under conditions such that a product including an oligomerized ester having residual hydroxyl groups is formed; and reacting the product with a capping agent under conditions such that an estolide derivative composition is formed. The compositions may exhibit desirably low pour point, desirable viscosity and thermoxidative stability, and a high level of renewable carbons, making them suitable for use as biolubricants, process fluids, plasticizers, or starting materials for polyurethane polymers.
