Adeegsada
Adipic acid waxa ay mari kartaa falcelin samaynta milixda, falcelinta esterification, falcelinta amidation, iwm.Adipic acid waa dicarboxylic acid oo muhiimad weyn u leh warshadaha.Waxay door muhiim ah ka ciyaartaa wax soo saarka kiimikaad, warshadaha isku-dhafka organic, daawada, iyo soosaarka saliidaha.Adipic acid sidoo kale waa walxo ceeriin ah oo loogu talagalay daawada, nadiifinta khamiirka, sunta cayayaanka, koollada, maqaarka synthetic, midabada synthetic iyo cadarka.
Adipic acid waxaa inta badan loo isticmaalaa sida alaabta ceeriin ee nylon 66 iyo balaastikada injineernimada.Waxaa sidoo kale loo isticmaalaa soo saarista alaabada ester ee kala duwan.Waxa kale oo loo istcimaalaa walxo ceeriin ah oo loogu talagalay elastomers-ka polyurethane iyo sida aashitada cuntada iyo cabitaanada kala duwan.In ka badan citric acid iyo tartaric acid.
Adipic acid sidoo kale waa walxo ceeriin ah oo loogu talagalay daawada, nadiifinta khamiirka, sunta cayayaanka, koollada, maqaarka synthetic, midabada synthetic iyo cadarka.
Adipic acid waxay leedahay dhadhan dhanaan oo jilicsan oo dheer, iyo qiimaha pH-ga ayaa isbeddelaya wax yar oo kala duwan oo xoog leh.Waa nidaamiye qiimaha pH ka fiican.GB2760-2007 waxay qeexaysaa in qiyaasta ugu badan ee isticmaalka alaabtan ee cabitaannada adag ay tahay 0.01g/kg;Waxa kale oo loo isticmaali karaa jelly iyo budada jelly, iyo xaddiga ugu badan ee isticmaalka jelly waa 0.01g/kg;marka loo isticmaalo budada jelly, waa la riixi karaa Hagaaji inta badan si loo kordhiyo isticmaalka.
Adipic acid ama hexanedioic acid waa isku dhafka organic ee caanaha
(CH2)4(COOH)2.Marka loo eego dhinaca warshadaha, waa dicarboxylic acid-ka ugu muhiimsan: qiyaastii 2.5 bilyan kiiloogaraam oo budada crystalline cad ayaa la soo saaraa sannadkii, inta badan horudhac u ah soo saarista naylon.Adipic acid haddii kale marar dhif ah ayay ku dhacdaa dabeecadda, laakiin waxaa loo yaqaannaa E355 cuntada lagu daro ee la soo saaray.
Qiyaastii 60% ee 2.5 bilyan kg ee adipic acid la soo saaro sannad kasta waxaa loo isticmaalaa sida monomer wax soo saarka naylon by falcelin polycondensation la hexamethylene diamine samaynta naylon 66. Codsiyada kale ee waaweyn ayaa sidoo kale ku lug polymers;waa monomer loogu talagalay soo saarista polyurethane iyo ester-keedu waa balaastiigiyeyaasha, gaar ahaan PVC.

Daawada:
Adipic acid waxaa lagu dhex daray kiniiniyada qaabaynta siidaynta la xakameeyey si loo helo sii daynta pH-madax banaan ee dawooyinka aashitada daciifka ah iyo kuwa daciifka ah labadaba.Waxa kale oo lagu daray dahaadhka polymeric ee nidaamyada monolithic hydrophilic si loo beddelo pH intragel, taasoo keentay in eber siideyso daawada hydrophilic.Kala-baxa xiidmaha xiidmaha ee shellak polymer enteric ayaa la sheegay in ay soo hagaagtay markii adipic acid loo isticmaalay sidii wakiilka daldaloolada iyada oo aan saameyn ku yeelan sii deynta warbaahinta acidic.Qaababka kale ee la xakameeyey ayaa waxaa ku jira adipic acid iyadoo ujeedadu tahay in la helo muuqaal sii dayn goor dambe ah.
Cuntooyinka:
Xaddi yar laakiin aad u badan oo adipic acid ah ayaa loo isticmaalaa walxo cunto ahaan sidii gargaar dhadhan iyo jeel.Waxaa loo isticmaalaa qaar ka mid ah antacids-ka calcium carbonate si ay u dhadhamiso.Sida acidulant ee budada dubista, waxay ka fogaataa sifooyinka hygroscopic ee aan loo baahnayn ee tartaric acid.Adipic acid, oo ah naadir dabiici ah, ayaa si dabiici ah ugu dhacda xididada, laakiin tani maaha ilo dhaqaale oo ganacsi marka loo eego isku-dhafka warshadaha.
Daryeelka badbaadada:
Adipic acid, sida inta badan asiidhyada karboxilic, waa maqaarka khafiifka ah ee xanaaqa.Waa sun yar, oo leh qiyaas dhexdhexaad ah oo dilaa ah oo ah 3600 mg/kg oo afka laga qaato jiirka.
Arrimaha deegaanka:
Soo saarista adipic acid waxay ku xidhan tahay qiiqa N2O, awood leh
gaaska aqalka dhirta lagu koriyo iyo sababta stratospheric ozone depletion.Soosaarayaasha adipic acid DuPont iyo Rhodia (hadda Invista iyo Solvay, siday u kala horreeyaan), habab ayaa la hirgeliyay si loogu beddelo nitrous oxide alaab aan waxyeello lahayn:
2 N2O → 2 N2 + O2
