US 8,476,350 B2 · Triglyceride plasticizer and process of making

Abstract

Provided are compositions, processes for making, and processes for using triglycerides as plasticizers. Triglyceride plasticizers can be produced by recovery of linear or branched C4 to C10 aldehydes from a hydroformylation product, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with glycerol, wherein the total carbon number of the triester groups is from 20 to 25 for greater than or equal to 45 wt % of the plasticizer. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or glass transition or pour point, low volatility, increased compatibility, and excellent low temperature properties in a range of polymeric resins.

Dependent claims

A process for producing a plasticizer comprising:

(i) recovering at least one linear C4 to C10 aldehyde, one branched C4 to C10 aldehyde, or a combination thereof from a hydroformylation product from a hydroformylation process including a hydroformylation reaction;
(ii) oxidizing the linear, branched or combination thereof C4 to C10 aldehyde to form a linear, branched or combination thereof C4 to C10 acid;
(iii) esterifying the linear, branched or combination thereof C4 to C10 acid with a polyol to yield a linear alkyl triglyceride, a branched alkyl triglyceride, or a combination thereof;
(iv) purifying the linear, branched or combination thereof alkyl triglyceride to form a plasticizer, wherein the total carbon number of triester groups ranges from 20 to 25 for greater than or equal to 45 wt % of the plasticizer and with the proviso that the plasticizer does not include aryl triglyceride.
