Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise hydrogenating the olefins under conditions sufficient to form a fuel composition. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.

Methods of refining natural oil feedstocks

Dibasic esters (diesters) and their use in plasticizer compositions are generally disclosed. In some embodiments, the diesters are branched-chain esters of long-chain alkanedioic acids, such as octadecanedioic acid. In some embodiments, such plasticizer compositions are used to increase the plasticity of a polymer resin, such as a vinyl chloride resin or poly vinyl butyral. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In some embodiments, at least a portion of the plasticizer is derived from a renewable source, such as a natural oil.

Dibasic esters and the use thereof in plasticizer compositions

Oligomers of certain glyceride compounds are generally disclosed herein. In some embodiments, the glyceride compounds include natural oil glycerides, such as glycerides derived from natural oils, such as palm oil, soybean oil, canola oil, and the like. Compositions containing such glyceride oligomers are also disclosed herein. Processes for making such glyceride oligomers are also disclosed herein. In some embodiments, the processes for making such compounds include reacting a plurality of unsaturated glyceride compounds in the presence of a metathesis catalyst.

High-weight glyceride oligomers and methods of making the same

Methods of carrying out metathesis reactions of natural oil-derived polyenes (e.g., dienes and trienes), including functionalized polyenes, are generally disclosed herein. In some embodiments, the dienes or trienes contain a terminal carbon-carbon double bond, and the metathesis reaction is selective toward reaction of the terminal carbon-carbon double bonds in the polyene. Compounds made by such methods are also generally disclosed herein.

Terminally selective metathesis of polyenes derived from natural oil

Methods for making specialty chemical products and chemical intermediates using hydroformylation are generally disclosed. Further, compositions and compounds formed using such methods are also disclosed. In some embodiments, methods are disclosed for refining a renewably sourced material, such as a natural oil, to form compositions, which can be further reacted employing the methods disclosed herein to form certain specialty chemical products or chemical intermediates.

Renewably derived aldehydes and methods of making and using the same

Methods of preparing ruthenium carbene complex precursors are disclosed herein. In some embodiments, the methods include reacting a ruthenium refinery salt with an L-type ligand and a reducing agent to form the ruthenium carbene complex precursor. Methods of preparing a ruthenium vinylcarbene complex are also disclosed. In some embodiments, preparing a ruthenium carbene complex includes converting a ruthenium carbene complex precursor into a ruthenium carbene complex having a structure (PRRR)ClRu&#x2550;CH&#x2014;R, wherein R, R, R, and Rare defined herein.

Methods for preparing ruthenium carbene complexes and precursors thereto

Various methods are provided for treating and reacting a metathesis feedstock. In one embodiment, the method includes providing a feedstock comprising a natural oil, chemically treating the feedstock with a metal alkoxide under conditions sufficient to diminish catalyst poisons in the feedstock, and, following the treating, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock.

Methods for treating a metathesis feedstock with metal alkoxides

High-purity dibasic acid compositions are generally disclosed. In some embodiments, the dibasic acid compositions are solutions or suspensions. In some other embodiments, the compositions are solid-state compositions. In some such embodiments, the solid-state compositions include a dibasic acid as a crystalline solid and further include a low quantity of certain impurities, such as monobasic acids, various esters, and the like. Methods and systems for making such high-purity dibasic acid compositions are also disclosed.

High-purity dibasic acid compositions and methods of making the same

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.

Natural oil metathesis compositions and methods

A method for preparing a ruthenium carbene complex precursor includes reacting a ruthenium refinery salt with a hydrogen halide to form a ruthenium intermediate, and reacting the ruthenium intermediate with an L-type ligand to form the ruthenium carbene complex precursor. A method for preparing a ruthenium vinylcarbene complex includes converting a ruthenium carbene complex precursor into a ruthenium hydrido halide complex, and reacting the ruthenium hydrido halide complex with a propargyl halide to form the ruthenium vinylcarbene complex. A method for preparing a ruthenium carbene complex includes converting a ruthenium carbene complex precursor into a ruthenium carbene complex having a structure (PRRR)ClRu&#x2550;CH&#x2014;R, wherein R, R, R, and Rare alike or different, and wherein covalent bonds may optionally exist between two or more of R, R, and R.
