  • Publication number: 20180208873
    Abstract: A metathesized natural oil composition comprising (i) a mixture olefins and/or esters, or (ii) a metathesized natural oil, is disclosed. The metathesized natural oil composition has a number average molecular weight in the range from about 100 g/mol to about 150,000 g/mol, a weight average molecular weight in the range from about 1,000 g/mol to about 100,000 g/mol, a z-average molecular weight in the range from about 5,000 g/mol to about 1,000,000 g/mol, and a polydispersity index of about 1 to about 20. The metathesized natural oil composition is metathesized at least once.

  • Patent number: 9856189
    Abstract: Methods and compositions are provided for refining natural oils and for producing high-weight esters, high-weight acids, and/or high-weight derivatives thereof, wherein the compositions are made by cross-metathesizing low-weight unsaturated esters or low-weight unsaturated acids having hydrocarbon chain lengths less than or equal to C24 with an olefin feedstock, thereby forming a metathesized product composition including high-weight esters or high-weight acids having hydrocarbon chain lengths greater than C18, wherein at least a portion of the hydrocarbon chain lengths in the metathesized product are larger than the hydrocarbon chain lengths in the starting feedstock.
