Adipic asidindi chinthu chofunikira kwambiri m'mafakitale chomwe chimagwira ntchito yayikulu m'mafakitale osiyanasiyana. Pagululi ndi loyera, lolimba la crystalline ndipo limagwiritsidwa ntchito kwambiri ngati kalambulabwalo wa nayiloni, polima yosinthika komanso yogwiritsidwa ntchito kwambiri. Kufunika kwake pakupanga nayiloni kumapangitsa kuti ikhale yofunika kwambiri pazinthu zosiyanasiyana monga zovala, makapeti, ndi zida zamagalimoto. Kuphatikiza apo, asidi adipic amapezanso ntchito popanga zinthu zosiyanasiyana zamafakitale monga ma resin a polyurethane, mapulasitiki, ndi zowonjezera zakudya.
Chimodzi mwazinthu zazikulu za adipic acid ndi kusinthasintha kwake. Kuthekera kwake kuchitapo kanthu ndi mitundu yambiri yamagulu ena kumapangitsa kukhala gawo lofunikira pakupanga zinthu zambiri. Mwachitsanzo, asidi adipic akakumana ndi hexamethylene diamine, amapanga nayiloni 66, chinthu cholimba kwambiri komanso chosagwira kutentha chomwe chimagwiritsidwa ntchito popanga zida zamagalimoto, nsalu zamakampani, ndi zinthu zosiyanasiyana zogula. Kuphatikiza apo, asidi adipic amatha kugwiritsidwa ntchito popanga utomoni wa polyurethane, womwe umagwiritsidwa ntchito popanga thovu, zokutira, ndi zomatira.
M'makampani azakudya, asidi adipic amagwiritsidwa ntchito ngati chowonjezera chazakudya kuti apatse kukoma kwa tart kuzinthu zosiyanasiyana. Nthawi zambiri amapezeka muzakumwa za kaboni, maswiti okoma zipatso, ndi mchere wa gelatin. Kukoma kwake kwa tart kumapangitsa kukhala chisankho chodziwika bwino chowonjezera kukoma kwazakudyazi komanso kukhala ngati chosungira kuti chiwonjezeke moyo wa alumali.
Kupanga kwa adipic acid kumaphatikizapo njira zingapo zamakina, ndipo njira yodziwika bwino ndiyo kutulutsa okosijeni wa cyclohexane kapena cyclohexanol. Njirazi zitha kuchitidwa pogwiritsa ntchito zopangira zosiyanasiyana komanso momwe zimakhalira kuti apange adipic acid wapamwamba kwambiri wokhala ndi katundu wogwirizana ndi zomwe akufuna.
Ubwino umodzi wa adipic acid ndi gawo lake polimbikitsa kukhazikika komanso kuyanjana ndi chilengedwe. Monga chinthu chofunikira kwambiri popanga nayiloni, asidi adipic amathandizira kupanga zinthu zopepuka, zolimba, komanso zopatsa mphamvu, zomwe ndizofunikira pakuchepetsa kutulutsa mpweya m'mafakitale osiyanasiyana. Kuphatikiza apo, kupanga adipic acid kwawona kupita patsogolo pankhani yogwiritsa ntchito zopangira zongowonjezwdwa ndikusintha magwiridwe antchito kuti achepetse kuwononga chilengedwe.
Pomaliza, adipic acid ndi chinthu chosunthika komanso chofunikira m'mafakitale chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Udindo wake pakupanga nayiloni, utomoni wa polyurethane, ndi zowonjezera zakudya zikuwonetsa kufunikira kwake monga chinthu chofunikira kwambiri popanga zinthu zosiyanasiyana. Ndi kupita patsogolo kopitilira muyeso ndikuyang'ana kukhazikika, adipic acid ikupitilizabe kugwira ntchito yofunika kwambiri pakupanga zida zamakono komanso zokomera zachilengedwe.
