4. I-electrolyte: Ngenxa yokuvuka kwayo kwe-ionic, isetshenziswa njenge-electrolyte kuzinhlelo ezithile zebhethri.
I-5. Umenzeli we-Extraction: I-NMF isetshenziswa kwinqubo yokukhipha, ikakhulukazi ekukhishweni kwezinsimbi ezithile kanye nezinhlanganisela ze-organic.
6. Ucwaningo: Elebhu, i-NMF isetshenziselwa izinhlelo ezahlukahlukene zocwaningo, kufaka phakathi lezo ezibandakanya ukuhlanganiswa kwe-organic kanye nesayensi yezinto zokwakha.
Isitoreji esivaliwe ukuvikela ukuvuza, gwema imvula, ukuvezwa, umthelela omkhulu kanye nokuxabana okukhulu.
Gwema kude nomlilo nemithombo yokushisa.
1. Isitsha: Sebenzisa iziqukathi ze-airtight ezenziwe ngezinto ezihambisanayo, njengengilazi noma amapulasitiki athile, ukuvikela ukungcoliswa nokuhwamuka.
2. Ukushisa: gcina i-NMF endaweni epholile, eyomile kude nokukhanya kwelanga okuqondile nokushisa. Ngokufanelekile, kufanele igcinwe emazingeni okushisa asekamelweni, kepha gwema ukuvezwa kwamazinga okushisa aphezulu.
I-3. Ukungena komoya
4. Ukungalingani: Sicela ugcine i-NMF kude ne-oxidants eqinile, ama-acid kanye nezisekelo njengoba kungasabela ngalezi zinto.
I-5. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, imininingwane yengozi, kanye nosuku lwerisidi ukuze uqinisekise ukuphathwa okufanele nokukhonjwa.
I-6. Imishini yokuzivikela (i-PPE): Uma uphatha i-NMF, sebenzisa i-PPE efanele njengamagilavu kanye nama-goggles ukunciphisa ukuvezwa.
7. Ukulahlwa: Lahla i-NMF nanoma yiziphi izinto ezingcolile ngokuhambisana nemithetho yendawo.
1. Uketshezi olungenamibala obonakalayo olungenalutho.
Kuyancibilika emanzini futhi kungancibilikisa usawoti we-inorganic.
I-hygroscopic futhi ibola kalula kwizixazululo ze-acidic noma ze-alkali.
Inuka nge-ammonia.
Izakhiwo zamakhemikhali zisebenzisana ne-hydrogen chloride ukwakha izinhlobo ezimbili zikasawoti;
I-HCONHCH3 · HLL ikhiqizwa kwi-solvents engeyona eye-polar;
(HCONHCH3) 2 · HL ikhiqizwa ngaphandle kwezixazululo.
Cishe akukho mphumela ngensimbi ye-sodium ekushiseni kwegumbi.
I-Hydrolysis yenzeka ngaphansi kwesenzo se-acid noma i-alkali.
Izinga le-acidic hydrolysis lingumuntu osebenza ngaphandle kweFormamide> N-Methylformamide> n, N-dimethylformamide.
Izinga le-Alkaline Hydrolysis yiFormamide-N-Methylformamide> n, N-dimethylformamide.
2. Ikhona entuthu ebhuqiwe.
1. Ukulandela umthetho wokulawula I-NMF ihlukaniswe njengento eyingozi ngakho-ke ingahle ibe ngaphansi kwemithetho ethile yokuthumela (isib. Inombolo ye-UN, igama elifanele lokuthumela).
2. Ukupakishwa: Sebenzisa izinto ezisebenza kahle zokufaka ezihambelana ne-NMF. Imvamisa, lokhu kufaka iziqukathi ezimelana namakhemikhali, iziqukathi zobufakazi obuvuzayo. Qinisekisa ukuthi iziqukathi zivalwe ngokuphephile ukuvikela ukuvuza ngesikhathi sokuhamba.
3. Ilebula: Ilebula ngokucacile ukupakishwa ngezimpawu ezifanele zengozi kanye nemininingwane, kufaka phakathi igama elifanele lokuthumela, inombolo ye-UN kanye nanoma yiziphi izexwayiso eziyingozi ezifanele. Lokhu kusiza ekuqinisekiseni ukuthi abaphathi bayakuqonda okuqukethwe yimpahla kanye nobungozi obuhlobene.
I-4. Imibhalo: Lungiselela futhi unamathisele wonke amadokhumenti adingekayo okuthumela, njengamashidi wedatha yokuphepha ngokwezinto ezibonakalayo (MSDS) nanoma yiziphi izimemezelo ezidingekayo ezidingekayo.
I-5
I-6. Ukuqeqeshwa: Qinisekisa ukuthi abasebenzi ababandakanyeka kwinqubo yokuhamba baqeqeshelwe ukuphatha izimpahla eziyingozi futhi baqonde ubungozi obuhambisana ne-NMF.
7. Izinqubo eziphuthumayo: Yiba nezinqubo zokuphendula eziphuthumayo ezikhona uma kwenzeka kuchitheka noma ukuvuza ngesikhathi sokuhamba. Lokhu kufaka ukuba nekhithi yokuchitheka kanye nemishini efanelekile yokuzivikela (i-PPE) isilungile.

1. Ukuphefumula: Ukuchayeka kuma-NMF Vapors kungacasukela ipheshana lokuphefumula, kubangele izimpawu njengokukhwehlela, ukufushane komoya, nokucasuka komphimbo. Ukuvezwa isikhathi eside noma okuphezulu kungadala izinkinga ezinkulu zokuphefumula.
2. Ukuxhumana kwesikhumba: I-NMF ingadala ukucasuka kwesikhumba futhi ingahle idonswe esikhunjeni, esingaphumela kwimiphumela emihle. Kunconywa ukugqoka amagilavu wokuvikela lapho usingatha lokhu okuqukethwe.
3. Ukuxhumana ngamehlo: Ukuxhumana ne-NMF kungadala ukucasuka kwamehlo, okuholele ekutheni ubomvu, izinhlungu, kanye nomonakalo ongaba khona.
4. Ukungenisa: Ukungenisa kwe-NMF kungaba yingozi futhi kungadala ukucasulwa kwesisu, isicanucanu, ukugabha, neminye imiphumela emibi yempilo.
I-5. Imiphumela yesikhathi eside: Ukuchayeka isikhathi eside ku-NMF kungakhiqiza ubuthi bokuzala nokuthuthuka. Ezinye izifundo zikhombisile ukuthi kungenzeka kube nemiphumela emibi ekuvukeni nasekuthuthukisweni kwengane.
I-6 Qinisekisa ukuthi indawo yokusebenza inomoya omuhle.
7. Izinyathelo eziphuthumayo: Uma kwenzeka uthintana, funa ukwelashwa ngokushesha futhi uthathe izindlela zokuqala zosizo, njengokufaka indawo ethintekile ngamanzi nokususa izingubo ezingcolisiwe.
