esterification: in the next step, phthalic anhydride is esterified with 2-ethylhexanol (2-eh) to produce dioctyl phthalate. this reaction is catalyzed by an acid catalyst, typically sulfuric acid. purification: the resulting mixture of DOP and unreacted 2-eh is then purified by fractional distillation to separate the DOP from the 2-eh.

dioctyl phthalate (DOP) chemical supplier exporter,dioctyl phthalate is one of the most widely used plasticizers in pvc due to its low cost. DOP is a general-purpose plasticizer and long-time industry standard known for its good stability to heat and ultraviolet light, and broad range of compatibility for use with pvc resins. dioctyl phthalate can also be used as dielectric and hydraulic fluids.
