QAAB-DHISMEEDKA:
Sharaxaad:
Asiidhka Isophthalic waa isku-dhis dabiici ah oo leh qaacidada C6H4(CO2H)2. Adkahan aan midab lahayn waa isomer ka kooban asiidhka phthalic iyo asiidhka terephthalic. Asiidhadan udgoonka leh ee dicarboxylic waxaa loo isticmaalaa sidii hordhac (qaab acyl chlorides ah) oo loogu talagalay polymers-ka muhiimka ah ee ganacsiga, tusaale ahaan walxaha u adkaysta dabka ee Nomex. Iyadoo lagu qaso asiidhka terephthalic, asiidhka isophthalic waxaa loo isticmaalaa soo saarista resins-ka dhalooyinka cabitaanka. Poly benzimidazole-ka polymer-ka ee waxqabadka sare leh waxaa laga soo saaraa asiidhka isophthalic.

Isticmaalka
Asiidhka Isophthalic waxaa loo isticmaalaa dhexdhexaad ahaan polyester-yada aan buuxin ee waxqabadka sare leh, resins-ka dahaarka, rinjiyada adag ee sare, jaakadaha jelka iyo wax ka beddelka polyethylene terephthalate ee dhalooyinka. Waxay u shaqeysaa sidii hordhac u ah walxaha nomex ee u adkaysta dabka iyo sidoo kale loo isticmaalo diyaarinta polybenzimidazole polymer-ka waxqabadka sare leh. Waxa kale oo loo isticmaalaa sidii wax lagu soo saaro agabka dahaarka.
Acid Isophthalic ah oo la safeeyey (PIA) waxaa inta badan loo isticmaalaa dhexdhexaad ahaan UPR-ka waxqabadka sare leh, resins-ka dahaarka, rinjiyada adag ee sare, jaakadaha jelka, iyo wax ka beddelka PET ee dhalooyinka.
