The esters of cyclohexane polycarboxylic acids may be used alone or in admixture with other plasticisers when the esters of cyclohexane polycarboxylic acids may act as viscosity depressants. Fast fusing plasticisers 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. | 11-06-2008 |

20100160506 | Production of synthetic hydrocarbon fluids, plasticizers and synthetic lubricant base stocks from renewable feedstocks - 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. | 06-24-2010 |

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. | 12-09-2010 |
20110021680 | Polyol Ester Plasticizers and Process of Making the Same - 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. | 01-27-2011 |

20120289636 | Cerium Catalyzed Production of Secondary Alcohols and Plasticizers Based on the Secondary Alcohols - 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. | 11-15-2012 |
