Provided are compounds of the following: wherein Ris a saturated or unsaturated cyclic hydrocarbon optionally substituted with an alkyl and/or an OXO-ester, and Ris a Cto Chydrocarbyl, preferably the residue of a Cto COXO-alcohol. Also provided are processes for making the compounds and plasticized polymer compositions containing said compounds.

Alkyl aromatic hydroalkylation for the production of plasticizers

Provided is a process for making non-phthalate plasticizers, by acylating an aromatic compound with a succinic anhydride to form a keto-acid, and then esterifying the keto-acid with C-COXO-alcohols to form a plasticizer compound. The aromatic rings of the aromatic compound may also be optionally hydrogenated.

Aromatic acylation with cyclic anhydride for plasticizer production

Resin plasticizers are produced by esterification of keto acids derived from acylation of aromatic compounds with cyclic anhydrides, and are particularly useful in making phthalate-free articles using PVC.

Keto acid esters as PVC plasticizers

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

A method for preparation of secondary alcohols with a high proportion of hydroxyl group at the C2 position is disclosed. Alkyl carboxylates, high in alpha-methylcarboxylate content, are produced via reaction of an alpha-olefin and a carboxylic acid in the presence of a cerium catalyst. The resultant alkyl carboxylate is hydrolyzed to yield a secondary alcohol with a high 2-hydroxyl content. The secondary alcohol may be used to prepare esters, especially phthalate esters or cyclohexanoate diesters, which are useful as plasticizers. These esters are more effective as plasticizers than esters derived from other secondary alcohols due to their high C2 point of attachment.

Cerium catalyzed production of secondary alcohols and plasticizers based on the secondary alcohols

The invention is directed to plasticized compositions comprising esters of terephthalic acid, particularly PVC compositions.

Polymer compositions comprising terephthalates

Compositions including a Cto Cphthalate ester containing titanium but in an amount less than 0.01 ppm by wt of titanium, prepared by titanium catalyzed esterification, and containing from 0.1 to 2.0 wt % of an antioxidant, are provided.

Compositions produced from plasticiser esters

The present invention relates to alcohols and in particular to Cto Calcohols that are used in the production of esters.

Processes relating to alcohols for the production of esters

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

Provided are compounds of the following: wherein Ris a saturated or unsaturated cyclic hydrocarbon optionally substituted with an alkyl and/or an OXO-ester, and Ris the residue of a Cto COXO-alcohol. Also provided are processes for making the compounds and plasticized polymer compositions containing said compounds.

Alkyl aromatic hydroalkylation for the production of plastisizers

Esters produced by the catalyzed reaction of alcohols and acids or anhydrides are neutralized by treatment with an aqueous alkaline alkali metal salt solution in an amount that provides less than a stoichiometric amount of alkali metal salt in relation to the acidity of the crude ester and the amount of water present during the treatment is from 0.8 to 1.4 wt % of water based on the weight of crude ester. When using titanium as the esterification catalyst, the ester resulting from this process contains less than 0.01 ppm by weight of titanium residue, so that it is storage stable when stored in the presence of an antioxidant.

Plasticiser esters

A method for performing a flying grade switch in an ester production process, which preferably is operated in semi-continuous mode, maximizes plant equipment productivity while minimizing product cross-contamination. Mixed ester products of the process containing a C-Calkyl or isodecyl benzoate together with a higher molecular weight di-alkyl phthalate or cyclohexanoate, bring performance advantages such as improved permanence in plasticized PVC articles or improved processability in manufacturing these articles.

Ester production

C7-C12 secondary alcohol esters of cyclohexanecarboxylic acids are especially useful as plasticizers for PVC and other plasticizable polymers. In embodiments, these plasticizers are useful in plastisol formulations to help improved processability of flexible PVC material. In other embodiments these same plasticizers can be used in blends with other plasticizers to improve processability. In preferred embodiments these same plasticizers can be used to prepare flexible PVC compounds with enhanced low temperature flexibility, low toxicity, and improved resistance to outdoor aging.
