  • Publication number: 20120289636
    Abstract: 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.

  • Patent number: 8283411
    Abstract: Esters of cyclohexane polycarboxylic acids are used as plasticizers for polyvinyl chloride to enable products with comparable mechanical properties to be obtained using less polyvinyl chloride. Use of these esters also produces formulations with increased stability to ultra-violet light, improved low temperature properties, lower viscosity and improved processability as well as reduced smoke on burning. The esters of cyclohexane polycarboxylic acids may be used alone or in admixture with other plasticizers when the esters of cyclohexane polycarboxylic acids may act as viscosity depressants. Fast fusing plasticizers may also be included. The formulations are particularly useful in the production of a range of goods from semi-rigid to highly flexible materials and are particularly useful in the production of medical materials such as blood bags and tubing.

  • Publication number: 20110147650
    Abstract: Compositions including a C6 to C13 phthalate ester containing titanium but in an amount less than 0.01 ppm by wt of titanium, prepared by titanium catalysed esterification, and containing from 0.1 to 2.0 wt % of an antioxidant, are provided.

  • Patent number: 7919649
    Abstract: 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 0.7 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.

  • Publication number: 20110021680
    Abstract: 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 plasticisers if before esterification with glycerol, an aryl acid is introduced together with the aliphatic acids.

  • Publication number: 20100310891
    Abstract: C4-C7 secondary aliphatic alcohol esters of cyclohexanediacid are especially useful as plasticizers for PVC. In embodiments, these fast fusing plasticizers are useful in plastisol formulations to help improve the processability of flexible PVC material. In preferred embodiments these same plasticizers can be used in blends with other plasticizers, especially slower fusing plasticizers or plasticizers with reduced solvency, such as di-2-propylheptyl phthalate or di-isononyl cyclohexanedicarboxylic acid, to improve processability.

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.

  • Publication number: 20100160506
    Abstract: 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.
