A process for converting a crude glycerol, crude mixtures of naturally derived multihydroxylated-aliphatic hydrocarbons or esters thereof to a chlorohydrin, by contacting the crude glycerol, crude mixtures of naturally derived multihydroxylated-aliphatic hydrocarbons or esters thereof starting material with a source of a superatmospheric partial pressure of hydrogen chloride for a sufficient time and at a sufficient temperature, and wherein such contracting step is carried out without substantial removal of water, to produce the desired chlorohydrin product; wherein the desired product or products can be made in high yield without substantial formation of undesired overchlorinated byproducts; wherein said crude glycerol, said ester of crude glycerol, or mixture thereof is derived from a renewable raw material. Chlorohydrins made by the process of the present invention are useful in preparing epoxides such as epichlorohydrins.

Process for the conversion of a crude glycerol, crude mixtures of naturally derived multicomponent aliphatic hydrocarbons or esters thereof to a chlorohydrin

The present invention relates to a process for converting a multihydroxylated-aliphatic hydrocarbon or ester thereof to a chlorohydrin, by contacting the multihydroxylated-aliphatic hydrocarbon or ester thereof starting material with a source of a superatmospheric partial pressure of hydrogen chloride for a sufficient time and at a sufficient temperature, and wherein such contracting step is carried out without substantial removal of water, to produce the desired chlorohydrin product; wherein the desired product or products can be made in high yield without substantial formation of undesired overchlorinated byproducts. In addition, certain catalysts of the present invention may be used in the present process at superatmospheric, atmospheric and subatmospheric pressure conditions with improved results.

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 &#x3b1;-olefin, and a reduced chain unsaturated acid or ester, preferably, a reduced chain &#x3b1;,&#x3c9;-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 &#x3b1;,&#x3c9;-hydroxy acid or &#x3b1;,&#x3c9;-hydroxy ester, which may be (trans)esterified with a polyol to form an &#x3b1;,&#x3c9;-polyester polyol. Alternatively, the reduced chain unsaturated acid or ester may be hydroformylated with reductive amination to produce an &#x3b1;,&#x3c9;-amino acid or &#x3b1;,&#x3c9;-amino ester, which may be (trans)esterified to form an &#x3b1;,&#x3c9;-polyester polyamine.
