TCC’s ChemFlexx DOTP Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate), commonly abbreviated DOTP, is an organic compound. It is the most important of the phthalate-free orthophthalate plasticizers. It is an environmentally safe, colorless viscous liquid that possesses good plasticizing properties.
TCC’s ChemFlexx DOTP is a general purpose, environmentally safer plasticizer than most orthophthalate plasticizers. It is used in extrusion, calendering, injection molding, rotational molding, dip molding, slush molding and in the manufacture of coatings.
TCC’s ChemFlexx DOTP Plasticizer is available for shipping throughout the continental United States with one (1) week lead time. Please call (401) 360-2800 for details. ChemFlexx DOTP is a liquid packed in bulk (rail, truck, ISO tanks), totes (IBC tanks), and drums.
TCC’s ChemFlexx DOTP Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate), commonly abbreviated DOTP, is an organic compound with the formula C6H4(C8H17COO)2. It is the most important of the phthlte-free plasticizers, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol. The environmentally safe, colorless, viscous liquid possesses very good plasticizing properties.
The production process entails the reaction of dimethyl terephthalate with 2-ethylhexanol:
C6H4(CO)2(OCH3)2 + 2 C8H17OH → C6H4(CO2 C8H17)2 + 2CH3OH
Several alternative plasticizers offer similar technical properties as DOTP after its phthalate-free nature. The alternatives include phthalates such as DINP, DOP, DPHP, DIDP and non-phthalates, e.g. DINCH and citrate esters.
