Adipic acidikemikari yakakosha yeindasitiri iyo inonyanya kushandiswa mukugadzira naironi. Inoshandiswawo mune zvimwe zvinoshandiswa senge mukugadzira polyurethane uye sekuwedzera kwechikafu. Munhau dzichangoburwa, pane zviitiko zvakakosha munyika yeadipic acid inofanirwa kukurukurwa.
Chimwe chezvinyanya kukosha zviri kuitika munyika yeadipic acid kuchinjika kune bio-based kugadzirwa. Sechinyakare, adipic asidhi yakagadzirwa kubva petrochemical masosi, asi nekunetseka kuri kukura pamusoro pekuchengetedza uye nharaunda, kwave nekusundidzira kugadzira bio-based dzimwe nzira. Izvi zvakonzera kugadzirwa kwenzira itsva dzekugadzira dzinoshandisa zviwanikwa zvinogonekazve zvakaita sebiomass nebiotechnology. Iyi shanduko yakanangana nekugadzirwa kwebio-based ibudiriro yakanaka sezvo ichidzikisa kuvimba neinogumira petrochemical zviwanikwa uye ine yakaderera kukanganisa kwezvakatipoteredza.
Chimwe chikamu chakakosha chenhau munyika yeadipic acid kuwedzera kwayo kushandiswa muindasitiri yemotokari. Adipic acid chinhu chakakosha mukugadzirwa kwenylon, iyo inoshandiswa mumhando dzakasiyana dzekushandisa mota. Izvi zvinosanganisira kugadzirwa kwezvinhu zvemotokari zvakaita semavhavha einjini, mabhegi emhepo, uye mitsara yemafuta. Nekukura kuri kudiwa kwezvinhu zvisingaremi uye zvinogara muindasitiri yemotokari, kudiwa kweadipic acid kunotarisirwa kuwedzera zvakanyanya mumakore anotevera.
Pamusoro pezvo, kwave nekufambira mberi mukushandiswa kweadipic acid mukugadzira polyurethane, iyo inoshandiswa zvakanyanya mukugadzira zvigadzirwa zvefuro sefenicha, matiresi, uye insulation. Izvi zvinonyanya kukosha sezvo maindasitiri ekuvaka nefenicha ari kuramba achikura, achifambisa kudiwa kwepolyurethane uye, zvakare, adipic acid. Iko kuvandudza matekinoroji matsva uye maitiro ekugadzira polyurethane uchishandisa adipic acid inotarisirwa kuenderera mberi nekufambisa kukura mumusika weadipic acid.
Pamusoro pekushandiswa kwayo kwemaindasitiri, adipic acid inoshandiswawo sechikafu chekuwedzera. Inowanzoshandiswa sechinhu chinonakisa uye se acidulant mune zvakasiyana siyana zvekudya uye zvinwiwa zvigadzirwa. Nekuwedzera kuri kuda kwezvikafu uye zvinwiwa zviri nyore, kushandiswa kweadipic acid muindasitiri yezvekudya kunotarisirwa kuramba kuchikura.
Pakazere, nhau dzichangoburwa munyika dzeadipic acid dzinoratidza kukosha kwayo sekemikari yakakosha yemaindasitiri. Shanduko yakanangana nekugadzirwa kwebio-based, kushandiswa kwayo kuri kuwedzera muindasitiri yemotokari, uye kufambira mberi mukushandiswa kwayo mukugadzirwa kwepolyurethane uye sekuwedzera kwechikafu zvese zvinonongedza kune ramangwana rakajeka readipic acid. Sezvo maindasitiri ari kuramba achikura nekushanduka, kudiwa kweadipic acid kuri kuwedzera, zvichiita kuti ive kemikari yakakosha yekuona mumakore anotevera.
