What is PTA? How is it synthetic and what is it’s application?

 

  • PTA(Pure terephthalic acid)is low toxic and flammable,n the form of white crystal or powder at normal temperature. PTA will be burning or even explosive in a certain limit of fire if mixed with air.Autoignition temperature: 680℃, ignition temperature: 384~421℃, sublimation heat: 98.4kJ /mol, combustion: 3225.9kJ/mol, , density: 155g/cm3. Dissolved in soluble in alkali, slightly dissolved in hot ethanol, but not in water, ether, glacial acetic acid and chloroform.
  • PX+Air(O2)acetic acid is the solventand
  • oxidized to xylic acid (oxidation), then xylic acid +H2 is purred to terephthalic acid through crystallization, filtration, washing and drying (purred).
  • PTA is the crucial raw material of making polyester resin film,fiber, insulating paint and engineering plastics. The capacity of PTA has been increased to 600 million T/year from 100 million/year in 2010, including on going projects such as Xin Fengming, Baihong and Dalian Hengli.
