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.

Description

FIELD OF THE INVENTION

[0001] The invention relates to triglyceride esters based on branched alkyl groups, useful as plasticizers and viscosity depressants for a wide range of resins. The invention further relates to a process for producing polyol ester plasticisers from carboxylic acids having branched alkyl chains, obtained by hydroformylation. The polyol esters may also comprise an aromatic acid group.BACKGROUND OF THE INVENTION

[0002] Plasticizers are incorporated into a resin (usually a plastic or elastomer) to increase the flexibility, workability, or distensibility of the resin. The largest use of plasticizers is in the production of “plasticized” or flexible polyvinyl chloride (PVC) products. Typical uses of plasticized PVC include films, sheets, tubing, coated fabrics, wire and cable insulation and jacketing, toys, flooring materials such as vinyl sheet flooring or vinyl floor tiles, adhesives, sealants, inks, and medical products such as blood bags and tubing, and the like.[00...
