[Chemical Properties]

Di-C9-11 phthalate (D911P) is a mixture of C9 and C11 esters of phthalic acid where different alcohols can be esterified to the same molecule of phthalic acid. It is a colorless, oily liquid. D911P is only minimally soluble in water (<0.1 mg/L). It has a neutral pH value.
[Uses]

D911P is used as a plasticizer in vinyl formulations. Major end uses include automotive vinyl, film, sheeting, and industrial vinyl sealant.
[Definition]

ChEBI: Di-n-octyl phthalate is a phthalate ester and a diester.
[Production Methods]

D911P is commercially produced by catalyzed esterification of phthalic anhydride with C9-11 alcohol blend utilizing batch or continuous processes. The individual process steps consist of a reaction step, excess alcohol removal, drying, and filtration. The final product has a phthalate ester content of well above 99.5%.
[Flammability and Explosibility]

Nonflammable
