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 plasticizer) chemicals supply,DOP plasticizer, or dioctyl phthalate, is a clear, colorless, and oily liquid commonly used to enhance the flexibility of plastics. it has a high boiling point and is insoluble in water but soluble in organic solvents like ethanol and ether. molecular formula: c₂₄h₃₈o₄; cas number: 117-81-7; grade: industrial grade; hs code.
