Gukoresha
Acide ya Adipic irashobora kugira imyunyu ngugu, reaction ya esterification, reaction ya amidation, nibindi, kandi irashobora kuba polycondensed hamwe na diamine cyangwa glycol kugirango ikore polymers nyinshi.Acide ya Adipic ni aside ya dicarboxylic ifite akamaro gakomeye mu nganda.Ifite uruhare runini mu gukora imiti, inganda ngengabihe, ubuvuzi, no gukora amavuta.Acide ya Adipic nayo ni ibikoresho fatizo byubuvuzi, kweza umusemburo, imiti yica udukoko, imiti yangiza, uruhu rwubukorikori, amarangi yubukorikori hamwe na parufe.
Acide ya Adipic ikoreshwa cyane nkibikoresho fatizo bya nylon 66 na plastiki yubuhanga.Irakoreshwa kandi mugukora ibicuruzwa bitandukanye bya ester.Ikoreshwa kandi nkibikoresho fatizo bya elastomers ya polyurethane kandi nka acide kubiryo n'ibinyobwa bitandukanye.Kurenza aside citricike na aside ya tartaric.
Acide ya Adipic nayo ni ibikoresho fatizo byubuvuzi, kweza umusemburo, imiti yica udukoko, imiti yangiza, uruhu rwubukorikori, amarangi yubukorikori hamwe na parufe.
Acide ya Adipic ifite uburyohe bworoshye kandi buramba, kandi pH agaciro gahinduka gake murwego runini.Nibyiza pH agaciro kayobora.GB2760-2007 iteganya ko umubare munini w’ibicuruzwa bikoreshwa mu binyobwa bikomeye ari 0.01g / kg;irashobora kandi gukoreshwa kuri poro ya jelly na jelly, kandi umubare ntarengwa wo gukoresha kuri jelly ni 0.01g / kg;iyo ikoreshejwe ifu ya jelly, irashobora gukanda Guhindura byinshi kugirango wongere imikoreshereze.
Acide ya Adipic cyangwa acide ya hexanedioic ni ifumbire mvaruganda hamwe na formula
(CH2) 4 (COOH) 2.Urebye mu nganda, ni aside irike ya dicarboxylic: hafi miliyari 2,5 z'ibiro by'ifu ya kristaline yera ikorwa buri mwaka, cyane cyane nk'ibibanziriza umusaruro wa nylon.Acide ya Adipic ubundi ntibikunze kubaho muri kamere, ariko bizwi nkibyakozwe E nimero yinyongera E355.
Hafi ya 60% ya miliyari 2,5 kg ya acide adipic ikorwa buri mwaka ikoreshwa nka monomer mugukora nylon hamwe na polycondensation reaction hamwe na diamine ya hexamethylene ikora nylon 66. Ibindi bikorwa byingenzi birimo polymers;ni monomer yo gukora polyurethane kandi est est ni plasitike, cyane cyane muri PVC.
Gusaba
Acide ya Adipic ikoreshwa cyane nkibikoresho fatizo bya nylon 66 na plastiki yubuhanga.Irakoreshwa kandi mugukora ibicuruzwa bitandukanye bya ester.Ikoreshwa kandi nkibikoresho fatizo bya elastomers ya polyurethane kandi nka acide kubiryo n'ibinyobwa bitandukanye.Kurenza aside citricike na aside ya tartaric.
Acide ya Adipic nayo ni ibikoresho fatizo byubuvuzi, kweza umusemburo, imiti yica udukoko, imiti yangiza, uruhu rwubukorikori, amarangi yubukorikori hamwe na parufe.
Acide ya Adipic ifite uburyohe bworoshye kandi buramba, kandi pH agaciro gahinduka gake murwego runini.Nibyiza pH agaciro kayobora.GB2760-2007 iteganya ko umubare munini w’ibicuruzwa bikoreshwa mu binyobwa bikomeye ari 0.01g / kg;irashobora kandi gukoreshwa kuri poro ya jelly na jelly, kandi umubare ntarengwa wo gukoresha kuri jelly ni 0.01g / kg;iyo ikoreshejwe ifu ya jelly, irashobora gukanda Guhindura byinshi kugirango wongere imikoreshereze.
Mu buvuzi:
Acide ya Adipic yinjijwe mububiko bwa matrix igenzurwa-kugirango ibone pH yigenga kubiyobyabwenge byibanze kandi bidakomeye.Yinjijwe kandi muri polymeric coating ya hydrophilique monolithic sisitemu kugirango ihindure intragel pH, bivamo ibiyobyabwenge bya hydrophilique.Gusenyuka kumara pH ya enteric polymer shellac byavuzwe ko bizagenda neza mugihe acide adipic yakoreshejwe nkigikoresho cyo gukora pore itagize ingaruka kubisohoka mubitangazamakuru bya acide.Ibindi bigenzurwa-kurekura byashyizwemo aside ya adipic hagamijwe kubona umwirondoro wo gutinda.
Mu biryo:
Umubare muto ariko wingenzi wa acide adipic ukoreshwa nkibiribwa nkibikoresho bifasha uburyohe.Ikoreshwa muri calcium ya karubone antacide kugirango ikorwe.Nka acide mu ifu yo guteka, irinda imiterere ya hygroscopique itifuzwa ya acide ya tartaric.Acide ya Adipic, idasanzwe muri kamere, ibaho mubisanzwe muri beterave, ariko iyi ntabwo ari isoko yubukungu mubucuruzi ugereranije no guhuza inganda.
Kwita ku mutekano:
Acide ya Adipic, kimwe na acide karubike nyinshi, ni uruhu rworoshye.Nuburozi bworoheje, hamwe na dose yica hagati ya 3600 mg / kg yo gufata umunwa nimbeba.
Ibidukikije:
Umusaruro wa acide adipic uhujwe no gusohora N2O, imbaraga
gaze ya parike nimpamvu ya stratospheric ozone igabanuka.Ku bicuruzwa bya adipic acide DuPont na Rhodia (ubu ni Invista na Solvay), inzira zashyizwe mubikorwa kugirango catalitike ihindurwe na aside nitrous mubicuruzwa byangiza:
2 N2O → 2 N2 + O2
