Acita a Terephthalic Ad

Oyeretsa Terephthalic Acid ndi okhazikika pompopompo ch 6 h 4 (CO 2 H ) 2 . Choyera ichi ndi chinthu   mankhwala , ogwiritsira ntchito makamaka ngati chotsogola kwa polyester   Pet , ntchito kupanga zovala ndi mabotolo apulasitiki . Oyeretsedwa Terephthalic acid amagwiritsa ntchito matani angapo miliyoni amapangidwa chaka chilichonse. Dzinalo limachokera ku mitengo yamtengopi ya turpentii ya turpentia terebinthus ndi Phthalic acid .

Pafupifupi PVC yopezeka padziko lonse lapansi ya terephthalic acid (pta) ndi dimethyl terephthalate amadyedwa ndi polythylene terefite (pet ). Kupanga Padziko Lonse mu 1970 kunali pafupifupi matani 1.75 miliyoni. Podzafika pa 2006, a Terephthalic acid acid (PTA) amafunikira kupitirira matani 30 miliyoni a vanyl. Chochepa kwambiri, koma chofunikira kwambiri kwa acid a acid alipo pakupanga polybutlene terephthalate ndi ma polima ena amiyala ina . Ma pibreeter a polyester kutengera PTA yoyera ya terephthalic acid amapereka chisamaliro chosavuta cha nsalu, zokha zokha komanso zophatikiza zachilengedwe ndi zina zokhala ndi pta . Makanema a polyester amagwiritsidwa ntchito kwambiri m'matepi ojambulidwa ndi makanema, matepi osungira ndalama, mafilimu ojambula, zilembo zina zokhudzana ndi mawonekedwe ake komanso kulimba .
