Adipic acid, dawb crystalline compound, yog ib qho tseem ceeb muaj nyob rau hauv zus tau tej cov nylon thiab lwm yam polymers. Txawm li cas los xij, nws cov ntawv thov txuas mus deb dhau ntawm thaj tsam ntawm cov hluavtaws fibers. Qhov kev sib xyaw ua ke no tau pom nws txoj hauv kev rau ntau yam kev lag luam, nthuav qhia nws ntau yam kev siv.
Ib qho ntawm cov kev siv tseem ceeb ntawm adipic acid yog nyob rau hauv kev tsim cov nylon 6,6, ib hom nylon dav siv nyob rau hauv textiles, automotive Cheebtsam, thiab industrial cov ntaub ntawv. Qhov muaj zog thiab ruaj khov ntawm nylon 6,6 tuaj yeem raug ntaus nqi vim muaj cov adipic acid hauv nws cov txheej txheem tsim khoom. Tsis tas li ntawd, adipic acid yog siv nyob rau hauv zus tau tej cov polyurethane, uas yog siv nyob rau hauv kev tsim ua npuas ncauj cushions, rwb thaiv tsev ntaub ntawv, thiab adhesives.
Hauv kev lag luam khoom noj khoom haus, adipic acid ua hauj lwm raws li cov khoom noj khoom haus additives, ua rau tartness ntawm tej yam khoom noj thiab dej haus. Nws yog feem ntau siv hauv cov dej haus carbonated, txiv hmab txiv ntoo-flavored dej haus, thiab ntau yam khoom noj. Nws lub peev xwm los txhim kho cov tsw qab thiab ua raws li tus neeg sawv cev buffering ua rau nws muaj txiaj ntsig zoo hauv cov khoom noj thiab dej haus.
Tsis tas li ntawd, adipic acid plays lub luag haujlwm tseem ceeb hauv kev tsim khoom ntawm ntau yam tshuaj thiab tshuaj pleev ib ce. Nws yog siv nyob rau hauv lub synthesis ntawm active tshuaj cov khoom xyaw thiab raws li ib tug tivthaiv nyob rau hauv daim tawv nqaij thiab cov khoom tu tus kheej. Nws muaj peev xwm hloov kho cov pH ntawm formulations thiab ua raws li tus neeg sawv cev stabilizing ua rau nws ib tug nrhiav-tom qab muaj nyob rau hauv cov kev lag luam.
Tshaj li nws cov kev siv ncaj qha, adipic acid kuj ua haujlwm ua ntej rau kev tsim khoom ntawm ntau yam tshuaj, suav nrog adiponitrile, uas yog siv rau hauv kev tsim cov yas thiab cov khoom siv hluavtaws.
Hauv kev xaus, kev siv ntawm adipic acid yog ntau haiv neeg thiab nyob deb. Los ntawm kev tsim cov nylon thiab polyurethane rau nws lub luag haujlwm hauv cov khoom noj, tshuaj, thiab tshuaj pleev ib ce, adipic acid txuas ntxiv ua kom pom nws cov kev ua tau zoo thiab qhov tseem ceeb hauv ntau yam haujlwm. Raws li thev naus laus zis thiab kev tsim kho tshiab txuas ntxiv mus, cov kev siv peev txheej ntawm adipic acid tuaj yeem nthuav dav ntxiv, ua kom nws txoj haujlwm yog qhov tseem ceeb hauv kev lag luam tshuaj.
