  • Beschreibung Dimethyl terephthalate (DMT) is an organic compound with the formula C6H4(CO2CH3)2. It is the diester formed from terephthalic acid and methanol. It is a white solid that melts to give a distillable colourless liquid.
  • Chemische Eigenschaften white chunks
  • Verwenden DMT is used in the production of polyesters, including polyethylene terephthalate (PET) and poly trimethylene terephthalate. It consists of benzene substituted with carboxy methyl groups (CO2CH3) at the 1 and 4 positions. Because DMT is volatile, it is an intermediate in some schemes for the recyclic of PET, e.g. from plastic bottles.
    Hydrogenation of DMT affords the diol cyclo hexane dimethanol , which is a useful monomer.

  • Vorbereitung Methode Dimethyl terephthalate (DMT) has been produced in a number of ways. Conventionally and still of commercial value is the direct esterification of terephthalic acid. Alternatively, it can be prepared by alternating oxidation and methyl-esterification steps from p-xylene via methyl-p-toluate.
  • Allgemeine Beschreibung White solid or heated colorless liquid. Has no odor. Liquid solidifies in cool water. Solid and liquid sink in water.
  • Air & Water Reaktionen When mixed with air, the vapor or dust forms very hazardous and highly reactive mixtures. . Insoluble in water.
  • Reaktivität anzeigen DIMETHYL TEREPHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250]. DIMETHYL TEREPHTHALATE is sensitive to heat. The molten material reacts with water due to the temperature. DIMETHYL TEREPHTHALATE is incompatible with strong oxidizers, strong acids and strong bases.
  • Health Hazard Molten DMT will cause severe burns of skin on contact.
  • Brandgefahr DIMETHYL TEREPHTHALATE is combustible.
  • Sicherheitsprofil Moderately toxic by intraperitoneal route. Mdly toxic by ingestion. An eye irritant. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes
  • läuterung methode Purify it by recrystallisation from aqueous EtOH, MeOH or CCl4; or by zone melting. [Beilstein 6 H 843, 6 III 4250, 6 IV 3303.] .
