Integrated processes of preparing industrial chemicals starting from seed oil feedstock compositions containing one or more unsaturated fatty acids or unsaturated fatty acid esters, which are essentially free of metathesis catalyst poisons, particularly hydroperoxides; metathesis of the feedstock composition with a lower olefin, such as ethylene, to form a reduced chain olefin, preferably, a reduced chain α-olefin, and a reduced chain unsaturated acid or ester, preferably, a reduced chain α,ω-unsaturated acid or ester. The reduced chain unsaturated acid or ester may be (trans)esterified to form a polyester polyolefin, which may be epoxidized to form a polyester polyepoxide. The reduced chain unsaturated acid or ester may be hydroformylated with reduction to produce an α,ω-hydroxy acid or α,ω-hydroxy ester, which may be (trans)esterified with a polyol to form an α,ω-polyester polyol. Alternatively, the reduced chain unsaturated acid or ester may be hydroformylated with reductive amination to produce an α,ω-amino acid or α,ω-amino ester, which may be (trans)esterified to form an α,ω-polyester polyamine.
A fatty acid or fatty acid ester composition comprising one or more unsaturated fatty acids or one or more unsaturated fatty acid esters, characterized as comprising less than 1.5 milliequivalents of metathesis catalyst poison(s) per kilogram (meq/kg) of fatty acid or fatty acid ester composition, wherein the metathesis catalyst poison comprises one or more organic hydroperoxides;
An olefin metathesis process comprising contacting a feedstock composition derived from a seed oil and comprising one or more unsaturated fatty acids or one or more unsaturated fatty acid esters with a lower olefin in the presence of a metathesis catalyst under metathesis process conditions sufficient to prepare a reduced chain olefin and a reduced chain unsaturated acid or unsaturated ester, the feedstock composition characterized as comprising less than 10 milliequivalents of metathesis catalyst poison(s) per kilogram (meq/kg) of feedstock composition wherein the metathesis catalyst poison comprises one or more organic hydroperoxides, and the feedstock composition is prepared by hydrolyzing a seed oil with water to obtain one or more unsaturated fatty acids or transesterifying a seed oil with a C1-8 alkanol to prepare one or more unsaturated fatty acid esters of the C1-8 alkanol, and thereafter contacting the one or more unsaturated fatty acids or one or more unsaturated fatty acid esters with an adsorbent to remove the metathesis catalyst poison(s) to a concentration of less than 10 meq/kg.
A process of preparing a polyester polyepoxide comprising (1) contacting a feedstock composition derived from a seed oil comprising one or more unsaturated fatty acids or one or more unsaturated fatty acid esters with a lower olefin in the presence of an olefin metathesis catalyst under metathesis process conditions sufficient to prepare a reduced chain unsaturated acid or reduced chain unsaturated ester;
A process of preparing a reduced chain α,ω-hydroxy acid, α,ω-hydroxy ester, and/or α,ω-diol comprising (1) contacting a feedstock composition comprising one or more unsaturated fatty acids or one or more unsaturated fatty acid esters with a lower olefin in the presence of an olefin metathesis catalyst under process conditions sufficient to prepare a reduced chain unsaturated acid or ester;
A process of preparing a reduced chain α,ω-amino acid, α,ω-amino ester, and/or α,ω-amino alcohol comprising (1) contacting a feedstock composition comprising one or more unsaturated fatty acids or one or more unsaturated fatty acid esters with a lower olefin in the presence of an olefin metathesis catalyst under process conditions sufficient to prepare a reduced chain unsaturated acid or ester;
