Triglyceride and other polyol ester PVC plasticizers can be produced by recovery of branched C6 to C9 aldehydes from a hydroformylation product, optional hydrogenation to the alcohol, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with glycerol, ethylene glycol, propylene glycol or mixtures thereof. The branched alkyl chains comprise at least 10% methyl branching. Special triglycerides are derived from branched aliphatic acids having alkyl chains with average carbon numbers from 6 to 9 and at least 10% methyl branching. These triglycerides are fast fusing plasticizers if before esterification with glycerol, an aryl acid is introduced together with the aliphatic acids.

Polyol ester plasticizers and process of making the same

The invention relates to polyketone compounds and the at least partially hydrogenated products thereof, the use of said polyketone compounds and/or the at least partially hydrogenated products thereof as plasticizers, processes of making polyketone compounds and the at least partially hydrogenated products thereof, compositions comprising the polyketone compounds and/or the at least partially hydrogenated products thereof, and to articles formed from products of the invention.

Polyketone plasticizers

Tetraesters of a C-Caliphatic tetracarboxylic acid and OXO-alcohols and plasticized compositions containing said tetraesters are provided.

Tetracarboxylic ester plasticizers

This disclosure is directed to an integrated method for making synthetic hydrocarbon fluids, plasticizers and polar synthetic lubricant base stocks from a renewable feedstock. More particularly, the disclosure is directed to a metathesis reaction of natural oil or its derivative ester and ethylene in the presence of an effective amount of a metathesis catalyst to form linear alpha-olefins, internal olefins and reduced chain length triglycerides. The linear alpha-olefins and/or internal olefins are polymerized to produce synthetic hydrocarbon fluids in the presence of a suitable catalyst. The reduced chain length triglycerides are converted into polar synthetic lubricant base stocks or plasticizers by hydrogenation, isomerization, followed by hydrogenations, or by hydroisomerization processes. Alternatively, the reduced chain length triglycerides can also be epoxidized to form epoxidized triglyceride plasticizers, optionally followed by carbonation, to form carbonated triglyceride plasticizers.

Production of synthetic hydrocarbon fluids, plasticizers and synthetic lubricant base stocks from renewable feedstocks

Acetals are formed from an aldehyde hydrogenation product mixture comprising alcohols and at most 2% of alde-hydes and the product is distilled to yield purified alcohols and a second stream containing acetals and/or unsaturated ethers.

Manufacture of purified alcohols

An alkylaromatic hydrocarbon composition prepared by the process which comprises oligomerizing an olefin selected from the group consisting of propylene, n-butene and mixtures thereof over an oligomerization catalyst, to form a oligomerization product comprising at least 95% by weight of mono-olefin oligomers of the empirical formula:CHwherein n is greater than or equal to 10, the mono-olefin oligomers comprise at least 20% by weight of olefins having at least 12 carbon atoms, and the olefins having at least 12 carbon atoms having an average of from 0.8 to 2.0 C-Calkyl branches per carbon chain. Sulfonation of the alkylaromatic hydrocarbon product produces an alkylaryl sulfonate mixture that exhibits advantageous properties, such as biodegradability and hard and cold water performance.

Preparation of alkylaromatic hydrocarbons and alkylaryl sulfonates

A process for the oligomerization of propylene is disclosed wherein a tungstated zirconia catalyst prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms useful for preparing neo acids.

Propylene oligomerization process

In a process for preparing an alkylaromatic hydrocarbon composition an olefinic hydrocarbon mixture and an aromatic compound are contacted under alkylation conditions with an aromatic alkylation catalyst selected from a homogeneous acid catalyst and heterogeneous acid catalyst comprising a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4&#xb1;0.25, 6.9&#xb1;0.15, 3.57&#xb1;0.07 and 3.42&#xb1;0.07 Angstroms. The olefinic hydrocarbon mixture comprises at least 5 wt % by weight of mono-olefin oligomers of the empirical formula:CHwherein n is greater than or equal to 10, the mono-olefin oligomers comprising at least 20 percent by weight of olefins having at least 12 carbon atoms, and the olefins having at least 12 carbon atoms having an average of from 0.8 to 2.0 C-Calkyl branches per carbon chain. Sulfonation of the alkylaromatic hydrocarbon product produces an alkylaryl sulfonate mixture that exhibits advantageous properties, such as biodegradability and hard and cold water performance.

The use of a controlled amount of water in a hydrogenation stage of the oxo process for the production of alcohols which uses at least two reactors in series improves the efficiency of the hydrogenation reaction and catalyst life as does a reduction in the amount of sulphur, chlorine and hydroformylation catalyst residues in the feed to hydrogenation.

Hydrogenation

In a process for oligomerizing a Cto Cn-olefin feedstock over surface deactivated ZSM-23, the feedstock contains from about 0.1 wt % to about 25 wt % of an iso-olefin and the C+ fraction of the oligomerized olefin product contains less than 0.5 atom % of quaternary carbon atoms.

Olefin oligomerization process

A selectivated molecular sieve, e.g., ZSM-22 or ZSM-23, is used as olefin oligomerization catalyst to provide product, e.g., octenes and dodecenes from butene, having a low degree of branching and hindered double bonds.

Oligomerization of olefins

A reduced or partially reduced nickel-molybdenum catalyst prepared by a process having the steps of 1) reacting nickel carbonate and molybdenum oxide precursors to form nickel molybdate and 2) treating the nickel molybdate under reducing conditions to form the reduced or partially reduced nickel-molybdenum catalyst. There is also a process for making the catalyst. There is also a process for using the catalyst in the hydrogenation of an oxo aldehyde, thereby forming an oxo alcohol of high selectivity. There is also a process for forming an oxo alcohol from the hydroformylation/hydrogenation of an olefinic feedstream. There is also a process for forming an oxo alcohol by contacting formates, dimers, trimers, and organic acids with hydrogen in the presence of a reduced or partially reduced nickel-molybdenum catalyst. The foregoing processes are also useful with a catalyst having the general formula YZ wherein Y is nickel and/or cobalt and Z is molybdenum and/or tungsten; and wherein x ranges between about 0.25 to about 4.0. There are also reduced or partially reduced catalysts of the general formula NiMo or YZ wherein x ranges between about 0.25 to about 4.0 and wherein oxide precursors of the catalysts are substantially free of ammonium groups.

The resultant mono-olefin oligomers comprise at least 20 percent by weight of olefins having at least 12 carbon atoms, wherein said olefins having at least 12 carbon atoms have an average of from about 0.8 to about 2.0 C&#x2013;Calkyl branches per carbon chain.
