Okuqukethwe
Kukhiqizwa cishe amathani ayizigidi ezi-3 e-adipic acid minyaka yonke. Cishe i-10% isetshenziswa embonini yokudla eCanada, emazweni e-EU, e-USA nakwamanye amazwe amaningi e-CIS.
Ukudla okunothe nge-adipic acid:
Izici ezijwayelekile ze-adipic acid
I-Adipic acid, noma njengoba ibizwa futhi, i-hexanedioic acid, i-E 355 ibhekwa yokudla edlala indima ye-stabilizer (i-acidity regulator), i-acidifier ne-baking powder.
I-Adipic acid isesimweni samakristalu angenambala ngokunambitheka okumuncu. Ikhiqizwa ngamakhemikhali ngokusebenzisana kwe-cyclohexane ne-nitric acid noma i-nitrogen.
Ucwaningo oluningiliziwe lwazo zonke izakhiwo ze-adipic acid luyaqhubeka njengamanje. Kutholakale ukuthi le nto ayinabuthi obuningi. Ngokuya ngalokhu, i-asidi inikezwa isigaba sokuphepha sesithathu. Ngokuya nge-State Standard (yomhla kaJanuwari 12.01, 2005), i-adipic acid inomthelela omubi kubantu.
Kuyaziwa ukuthi i-adipic acid inomthelela omuhle ekunambitheni komkhiqizo ophelile. Kuthinta izakhiwo zomzimba nezamakhemikhali zenhlama, kuthuthukisa ukubukeka komkhiqizo ophelile, ukwakheka kwawo.
Isetshenziswe embonini yokudla:
- ukuthuthukisa ukunambitheka kanye nezici zomzimba namakhemikhali emikhiqizo eqediwe;
- ukugcinwa isikhathi eside kwemikhiqizo, ukuyivikela ekonakaleni, i-antioxidant.
Ngaphezu komkhakha wokudla, i-adipic acid nayo iyasetshenziswa embonini ekhanyayo. Isetshenziselwa ukukhiqizwa kwemicu ehlukahlukene eyenziwe ngabantu, njenge-polyurethane.
Abakhiqizi bavame ukuyisebenzisa kumakhemikhali asendlini. Ama-esters e-adipic acid atholakala ezimonyoni zokunakekelwa kwesikhumba. Futhi, i-adipic acid isetshenziswa njengengxenye yemikhiqizo eklanyelwe ukususa isikali namadiphozithi emishini yasendlini.
Isidingo somuntu sansuku zonke se-adipic acid:
I-adipic acid ayakhiqizwa emzimbeni, futhi ayiyona into edingekayo ekusebenzeni kwayo. Isilinganiso esivunyelwe nsuku zonke se-asidi singu-5 mg nge-1 kg yesisindo somzimba. Isilinganiso esiphezulu se-asidi emanzini naseziphuzweni asikho ngaphezu kuka-2 mg nge-1 litre.
Isidingo se-adipic acid siyanda:
I-Adipic acid ayiyona into ebalulekile emzimbeni. Isetshenziselwa kuphela ukuthuthukisa izinga lokudla okunempilo kanye nempilo yeshalofu yemikhiqizo eqediwe.
Isidingo se-adipic acid siyancipha:
- ebuntwaneni;
- contraindicated ngesikhathi sokukhulelwa kanye lactation;
- ngesikhathi sokuzijwayeza ngemuva kokugula.
Ukwenziwa kwe-adipic acid
Kuze kube manje, umphumela wento ethile emzimbeni awukakafundwa ngokuphelele. Kukholakala ukuthi lesi sengezo sokudla singasetshenziswa ngamanani alinganiselwe.
I-asidi ayimuncwa ngokuphelele ngumzimba: ingxenye encane yalesi sici iphukile kuwo. I-adipic acid ikhishwa emchameni nasemoyeni ophefumulayo.
Izakhiwo eziwusizo ze-adipic acid nomphumela wayo emzimbeni:
Azikho izici ezizuzisayo zomzimba womuntu ezitholiwe. I-Adipic acid inomphumela omuhle kuphela ekulondolozweni kwemikhiqizo yokudla, izici zayo zokunambitha.
Izici ezithinta okuqukethwe kwe-adipic acid emzimbeni
I-Adipic acid ingena emzimbeni wethu kanye nokudla, kanye nalapho sisebenzisa amanye amakhemikhali asendlini. Inkambu yomsebenzi ithinta nokuqukethwe yi-asidi. Ukuhlungwa okuphezulu kwento engena endaweni yokuphefumula kungacasula ulwelwesi lwamafinyila.
Inani elikhulu le-adipic acid lingangena emzimbeni ngesikhathi kwenziwa imicu ye-polyurethane.
Ukugwema imiphumela emibi yezempilo, kunconywa ukuthi ugcine zonke izindlela zokuqapha ezidingekayo ebhizinisini, uhambisane nezindinganiso zenhlanzeko. Inani eliphakeme elivunyelwe lokuqukethwe kwezinto ezisemoyeni lingu-4 mg nge-1 m3.
Izimpawu ze-adipic acid eyeqile
Okuqukethwe kwe-asidi emzimbeni kungatholakala kuphela ngokudlulisa izivivinyo ezifanele. Kodwa-ke, esinye sezibonakaliso zokweqisa kwe-adipic acid singaba nesizathu (isb., I-allergen) ukucasuka kolwelwesi lwamafinyila kanye nohlelo lokuphefumula.
Azikho izimpawu zokushoda kwe-adipic acid ezitholakele.
Ukusebenzisana kwe-adipic acid nezinye izinto:
I-Adipic acid iphendula kalula nezinye izinto zokulandela umkhondo. Isibonelo, into iyancibilika kakhulu futhi icwilisa emanzini, iziphuzo ezinhlobonhlobo ezihlukene.
Ngaphansi kwezimo ezithile kanye namavolumu, into leyo ihlangana ne-acetic acid, i-hydrocarbon. Ngenxa yalokhu, ama-ether ayatholakala, athola ukusetshenziswa kwawo emagatsheni ahlukahlukene empilo yomuntu. Isibonelo, enye yalezi zinto ezibalulekile isetshenziselwa ngqo ukuthuthukisa ukunambitheka okumuncu ekudleni.
I-Adipic acid ku-cosmetology
I-Adipic acid iyingxenye ye-antioxidants. Umsebenzi oyinhloko wokusetshenziswa kwawo ukunciphisa i-asidi, ukuvikela imikhiqizo yezimonyo equkethe ukuwohloka kanye ne-oxidation. Ama-esters angumphumela we-adipic acid (diisopropyl adipate) avame ukufakwa kumakhilimu aklanyelwe ukwenza isimo sesikhumba sibe sejwayelekile.
