    摘要: A process for making 2,3-dihalopropanol including reacting 2,3-dihalopropanal with a hydrogenating agent in the presence of an iridium and a second transition metal mixed metal catalyst where the second transition metal is selected from the group comprising ruthenium, iron, molybdenum, tungsten, rhenium, osmium, manganese or vanadium, under conditions such that 2,3-dihalopropanol is formed. The 2,3-dihalopropanol is particularly useful in a process for making epihalohydrin.

    摘要: 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,ωpolyester polyamine.

    摘要: A process of preparing an unsaturated alcohol (olefin alcohol), such as, a homo-allylic mono-alcohol or homo-allylic polyol, involving protecting a hydroxy-substituted unsaturated fatty acid or fatty acid ester, such as methyl ricinoleate, derived from a seed oil, to form a hydroxy-protected unsaturated fatty acid or fatty acid ester; homo-metathesizing or cross-metathesizing the hydroxy-protected unsaturated fatty acid or fatty acid ester to produce a product mixture containing a hydroxy-protected unsaturated metathesis product; and deprotecting the hydroxy-protected unsaturated metathesis product under conditions sufficient to prepare the unsaturated alcohol. Preferably, methyl ricinoleate is converted by cross-metathesis or homo-metathesis into the homo-allylic mono-alcohol 1-decene-4-ol or the homo-allylic polyol 9-octadecene-7,12-diol, respectively.
