  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,ω­polyester 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.

  从含有一种或多种不饱和脂肪酸或不饱和脂肪酸酯的种子油原料组合开始准备工业化学品的集成过程，这些原料组合基本上不含有异构化催化剂毒素，特别是过氧化物；将原料组合与较低的烯烃（如乙烯）进行异构化，形成减少的链烯烃，最好是减少的链α-烯烃，以及减少的链不饱和酸或酯，最好是减少的链α,ω-不饱和酸或酯。减少的链不饱和酸或酯可以（转）酯化形成聚酯聚烯烃，可以对其进行环氧化形成聚酯聚环氧化物。减少的链不饱和酸或酯可以通过还原进行氢甲酰化，产生α,ω-羟基酸或α,ω-羟基酯，可以与多元醇（转）酯化形成α,ω-聚酯多元醇。另外，减少的链不饱和酸或酯可以通过还原胺化进行氢甲酰化，产生α,ω-氨基酸或α,ω-氨基酯，可以（转）酯化形成α,ω-聚酯聚胺。

  The present invention provides a polyester polyol, preferably a plant-derived polyester polyol, suitable for a composition for polyurethane foam that contributes to the reduction of load on the environment and has a good balance of high resilience, moderate hardness, and high durability as a cushioning material for vehicle seat cushions. A polyester polyol having a hydroxyl value in the range of 15 to 100 mgKOH/g according to the present invention is produced by a condensation of raw materials comprising at least one selected from the group consisting of fatty acids having a hydroxy group and fatty acid esters having a hydroxy group with a polyhydric alcohol having an average number of functional groups of more than three but not more than eight. The raw materials contain 90% to 100% by mass of a fatty acid having a hydroxy group and a fatty acid ester having a hydroxy group in total.
