1,2-Benzenedicarboxylic acid di-C9-11-branched alkyl esters C10-rich Usage And Synthesis
Chemical Properties
The empirical formula of diisodecyl phthalate (DIDP) is C28H46O4. The structural formula of DIDP varies because the iso-alcohols used in the manufacture contain several isomers. DIDPis insoluble in water, but it is soluble in organic solvents.
Uses
It is a high-molecular-weight, general-purpose plasticizer that is added to polyvinyl chloride to impart flexibility.
Definition
ChEBI: Diisodecyl phthalate is a phthalate ester and a diester. Used as plasticizer for polyvinyl chloride in calendered film, coated fabrics, building wire jackets, wire and cable extrusion, and other applications.
Production Methods
DIDP is manufactured by the esterification of phthalic anhydride with isodecyl alcohol in the presence of a catalyst.
Flammability and Explosibility
Non flammable
Carcinogenicity
A 2-year bioassay was conducted in which DIDP was administered in the diet at concentrations of 400, 2000, and 8000 ppm to F344 rats. Rats of both sexes exhibited significant decreases in overall survival and body weights and increases in the relative weights of kidneys and liver with 8000 ppm of DIDP. No treatment-related neoplastic lesions were observed in the internal organs, including the liver. In addition, measurement of catalase enzyme activity, a marker for cell peroxisome proliferating activity, suggests that DIDP can induce peroxisome proliferation at an early stage (12 weeks of treatment) but fails to maintain the catalase-inducing potential by 32 weeks of treatment. An increased incidence of MNCL was observed in this study, butMNCLis a common neoplasm in F344 rats; the observed increased incidence is likely to be a species-specific effect with little or no relevance to humans. Therefore, DIDP was not considered to be carcinogenic at doses up to 8000 ppm in rats.
