Catalyst compositions are prepared by contacting a palladium source and 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane and a methoxyocta-diene compound, in a primary aliphatic alcohol, under suitable conditions including a ratio of equivalents of palladium to equivalents of 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane ranging from greater than 1:1 to 1:1.3. The result is a complex of palladium, a 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaada-mantane ligand, and a ligand selected from a methoxyoctadiene ligand, an octadienyl ligand, or a protonated octadienyl. Such complexes may, in solution, exhibit surprising solubility and storage stability and are useful in the telomerization of butadiene, which is a step in the production of 1-octene.

Butadiene telomerization catalyst and preparation thereof

A method for forming 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane includes obtaining a solution comprising an ethereal solvent and an aluminum hydride, adding dichloro(2,4-dimethoxyphenyl)phosphine to the solution to produce 2,4-dimethoxyphenylphosphine, and reacting the 2,4-dimethoxyphenylphosphine with an acidic mixture comprising diones to produce 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane. The solution has a temperature from IN greater than &#x2212;20 C. to 50 C. throughout the method. Another method for forming 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-tri-oxa-6-phosphaadamantane includes obtaining dichloro(2,4-dimethoxyphenyl)phosphine, forming 2,4-dimethoxyphenylphosphine by adding the dichloro(2,4-dimethoxyphenyl)phosphine to a solution comprising at least one solvent and an aluminum hydride, reacting the 2,4-dimethoxyphenylphosphine with a mixture to produce 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane. The mixture includes an acid selected from the group consisting of Lewis acids, sulfonic Bronsted acids, and mixtures thereof, an aromatic or non-aromatic hydrocarbons; and acetylacetone.

Use a solvent blend that contains 1-methoxy-2,7-octadiene and an alkanols rather than the alkanols by itself to prepare a catalyst precursor suitable for use in butadiene telomerization.

Butadiene telomerization catalyst precursor preparation

An aryl phosphine with fused ring ortho-alkoxy substitution that includes an aryl monophosphine and an aryl bi-sphosphme.

Aryl phosphines with fused ring ortho-alkoxy substitution

Olefins are produced by the reductive dehydroxylation of vicinal polyols or esters thereof, or a combination thereof, in a liquid reaction medium, under a hydrogen atmosphere, at a temperature from 50&#xb0; C. to 250&#xb0; C., in the presence of a halogen-based, preferably iodine-based, catalyst. Examples of the catalyst, which may be included independently or generated in situ, are iodine (I), hydroiodic acid (HI), iodic acid (HIO), lithium iodide (LiI), and combinations thereof.

Iodine-based catalyst for reductive dehydroxylation of vicinal polyols to olefins

A process for the telomerization of butadiene comprises reacting 1,3-butadiene and an alkanol, in the presence of a catalyst promoter and an alkoxydimerization catalyst comprising a Group VIII transition metal and a triarylphosphine ligand, which includes one phenyl that is mono-ortho-alkoxy substituted and at least one other phenyl including at least one substituent that withdraws electrons from the phosphorus atom. The product includes an alkoxy-substituted octadiene, which may then be used to produce 1-octene. The catalyst shows improved stability, activity and selectivity toward the alkoxy-substituted octadiene.

The phosphine ligand has a total of two (2), three (3), four (4), five (5), or six (6) substituted or unsubstituted C-C-hydrocarbyloxyls, and optionally, any two adjacent substituents on an Ar group can be bonded to form a 5- to 7-membered ring.

Process and apparatus for producing 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 hydrogen chloride at superatmospheric, atmospheric and subatmospheric pressure conditions for a sufficient time and at a sufficient temperature, preferably 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; said process carried out without a step undertaken to specifically remove volatile chlorinated hydrocarbon by-products or chloroacetone, wherein the combined concentration of volatile chlorinated hydrocarbon by-products and chloroacetone is less than 2000 ppm throughout any stage of the said process.
