  • Patent number: 10532972
    Abstract: Dibasic esters (diesters) and their use in plasticizer compositions are generally disclosed. In some embodiments, the diesters are branched-chain esters of long-chain alkanedioic acids, such as octadecanedioic acid. In some embodiments, such plasticizer compositions are used to increase the plasticity of a polymer resin, such as a vinyl chloride resin or poly vinyl butyral. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In some embodiments, at least a portion of the plasticizer is derived from a renewable source, such as a natural oil.

  • Patent number: 9382502
    Abstract: Methods are provided for refining natural oil feedstocks and producing isomerized esters and acids. The methods comprise providing a C4-C18 unsaturated fatty ester or acid, and isomerizing the fatty acid ester or acid in the presence of heat or an isomerization catalyst to form an isomerized fatty ester or acid. In some embodiments, the methods comprise forming a dibasic ester or dibasic acid prior to the isomerizing step. In certain embodiments, the methods further comprise hydrolyzing the dibasic ester to form a dibasic acid. In certain embodiments, the olefin is formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having unsaturated esters.

  • Patent number: 9365487
    Abstract: Methods and systems for making dibasic esters and/or dibasic acids using metathesis are generally disclosed. In some embodiments, the methods comprise reacting a terminal olefin ester with an internal olefin ester in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In some embodiments, the terminal olefin ester or the internal olefin ester are derived from a renewable feedstock, such as a natural oil feedstock. In some such embodiments, the natural oil feedstock, or a transesterified derivative thereof, is metathesized to make the terminal olefin ester or the internal olefin ester.
