Njengempahla eluhlaza yamakhemikhali esebenzayo,i-sulfamic acididlala indima ebalulekile embonini kadayi. Izici zayo zamakhemikhali eziyingqayizivele ziyenza isetshenziswe kabanzi ekuhlanganiseni udayi nasezinkambisweni zokudaya. Angeke isetshenziswe kuphela njengesisizi se-catalyst ukuze kuthuthukiswe ukusebenza kahle kokuhlanganiswa kodayi, kodwa futhi ingasetshenziswa ukulungisa inani le-pH lenqubo yokudaya ukuze kwandiswe ukutholakala kodayi nokushesha kombala. Lesi sihloko sihlola izindima ezibalulekile ezidlalwa yi-sulfamic acid ekukhiqizeni udayi kanye nezinzuzo zayo embonini.
1.Ukuqeda i-nitrite eyeqile
Ku-dayi synthesis, ukusabela kwe-diazotization kuyisinyathelo esibalulekile ekukhiqizeni odayi be-azo. Ukusabela kuvame ukusebenzisa i-sodium nitrite ne-hydrochloric acid ukukhiqiza i-nitrous acid, ehlangana nama-amine anephunga elimnandi ukwenza usawoti we-diazonium. Kodwa-ke, uma i-nitrite eyeqile ingelashwa ngesikhathi, izodala ukungcoliswa kwemvelo, futhi i-nitrite eyengeziwe ingase isabele ngama-molecule odayi, okuthinta umbala nokuzinza kokukhanya kwedayi. Ngakho-ke, i-aminosulfonic acid isetshenziswa kabanzi embonini kadayi njengesikhiphi se-nitrite esisebenzayo nesiphephile. Umgomo wokusabela umi kanje:
NaNO₂ + H₃NSO₃ → N₂ + NaHSO₄ + H₂O
I-aminosulfonic acidisabela ngokushesha nge-nitrite futhi ingaguqula ngempumelelo i-nitrite eyeqile ibe igesi ye-nitrogen engenangozi.
- Izinhlelo zokusebenza eziqondile
Ngemuva kokwelashwa kokusabela kwe-diazotization: Ngemva kokuqedwa kokusabela kwe-diazotization, engeza inani elifanele lesisombululo se-aminosulfonic acid bese ushukumisa ukusabela isikhathi esithile ukuze uqede ngokuphelele i-nitrite eyeqile.
Ukuhlanzwa okuphakathi kwedayi: Enqubweni yokulungiselela ama-intermediates odayi, i-aminosulfonic acid ingasetshenziswa ukususa i-nitrite esele futhi kuthuthukiswe ubumsulwa bomkhiqizo.
Ukwelashwa kwamanzi angcolile: Kumanzi angcolile okudayi aqukethe i-nitrite, i-aminosulfonic acid ingasetshenziselwa ukwelashwa ukuze kuncishiswe ukugcwala kwe-nitrite emanzini angcolile nokunciphisa ukungcoliswa kwemvelo.
2. Ukuqiniswa Kwezixazululo Zedayi
Embonini kadayi, ukuzinza kwezixazululo zikadayi kubalulekile ukuze kuqinisekiswe imibala efanayo futhi engaguquki. I-Sulfamic acid isebenza njenge-ejenti yokuzinzisa, ivimbela i-hydrolysis ngaphambi kwesikhathi kanye nokuwohloka kwama-molecule odayi ngesikhathi sokugcinwa nokusetshenziswa. Lesi sici sibaluleke kakhulu kumadayi asebenzayo, lapho ukugcina ubuqotho bamakhemikhali kubalulekile ukuze kuzuzwe imibala egqamile nehlala isikhathi eside.
3. Ukulawula i-pH
Ukusebenza kodayi abaningi kuncike ekugcineni izinga elithile le-pH. I-Sulfamic acid, eyaziwa ngokuba ne-asidi ethambile, isebenza njengesilungisi se-pH ezindaweni zokugeza zikadayi. Ngokulawula kahle i-pH, iqinisekisa izimo ezifanele zokulungiswa kodayi kumafayibha, ithuthukisa ukusebenza kahle kokudaya iyonke futhi inciphise ubungozi bombala ongalingani noma amaphutha.
4. Ukwehliswa kanye Nokuhlanza Izinsiza Zokudayi
Ukukhiqizwa nokufakwa kodayi kuvame ukuholela ekuqongeleleni isikali nezinsalela kumishini. Izakhiwo ezinamandla zokwehlisa i-sulfamic acid ziyenza i-ejenti yokuhlanza enhle kakhulu yokukhipha la madiphozithi ngaphandle kokulimaza umshini. Ukuhlanza njalo nge-sulfamic acid akugcini nje ngokuthuthukisa impilo yemishini kodwa futhi kuqinisekisa ukuthi inqubo yokudaya ihlala ingangcolisiwe, okuholela emikhiqizweni ephezulu.
5. Ukuthuthukisa Ikhwalithi Yokudaya KumaFibers
I-Sulfamic acid ithuthukisa ukungena nokulungiswa kodayi emicu enjengokotini, uvolo, nezinto zokwenziwa. Ngokwenza indawo ene-asidi efanelekile, iqinisekisa ukumuncwa okungcono nokubopha ama-molecule kadayi kufiber, okuholela emibaleni egqamile futhi ehlala isikhathi eside. Lokhu kuwusizo ikakhulukazi ezimbonini zendwangu ezidinga ukuqedwa kwekhwalithi ephezulu.
Indima ye-Sulfamic acid embonini kadayi inezici eziningi, kusukela ekuqiniseni izixazululo zikadayi kuya ekuthuthukiseni izinga likadayi, izinto zokuhlanza, nokuhlanza amanzi angcolile. Izakhiwo zayo eziyingqayizivele nezici ezivumelana nemvelo ziyenza ibe yimpahla ebalulekile kubakhiqizi abafuna ukusebenza kahle nokusimama.
