Abstract
Official abstract text for this publication.
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 4 -C 13 OXO-alcohols to form a plasticizer compound. The aromatic rings of the aromatic compound may also be optionally hydrogenated.
First claim
Opening claim text (preview).
What is claimed is: 1. A plasticizer compound of the formula: wherein R 1 is selected from the group consisting of H, C 1 -C 9 linear or branched alkyl, cycloalkyl, or C 1 -C 4 ether, and wherein there may be 1 or 2 R 1 groups present on the aromatic or saturated ring which may be the same or different, R 2 is the alkyl residue of C 4 to C 13 OXO-alcohols, R 3 is…
