1,2-Benzenedicarboxylic acid, di-C7-11-branched and linear alkyl esters Usage And Synthesis

Chemical Properties

Di-C7-11-phthalate (D711P) is a mixture of C7, 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. D711P is only minimally soluble in water (<0.1 mg/L). It has a neutral pH value.

Uses

D711P is commercially produced by catalyzed esterification of phthalic anhydride with C7-9-11 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%. D711P is used as a plasticizer in vinyl formulations. Major end uses include automotive vinyl, film, sheeting, and industrial vinyl sealant.

Uses

Dialkyl Phthalate (Alkyl=heptyl, nonyl, undecyl) can be used as a plasticizer.
