Incazelo emfushane:

I-Tetrabutylurea (TBU) ngokuvamile iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile. Inokuvumelana kwe-viscous futhi yaziwa ngephunga layo eliyisici, elingachazwa njengelithambile noma elimnandi kancane. I-TBU iyancibilika kuzincibilikisi zemvelo futhi inokuguquguquka okuphansi uma kuqhathaniswa.

I-Tetrabutylurea cas 4559-86-8 ingasetshenziswa ukulungisa ama-plasticizer kanye neziqinisi zezibulala-zinambuzane, imithi, odayi, namapulasitiki.

Isicelo

I-Tetrabutylurea (TBU)iyinhlanganisela esetshenziswa ngokuyinhloko njenge-solvent kanye ne-reagent ezinhlobonhlobo zezicelo zamakhemikhali. Ulwazi oluthe xaxa, sicela ubheke okulandelayo:
 
1. I-solvent ku-organic synthesis:I-1,1,3,3-Tetrabutylurea ivame ukusetshenziswa njenge-solvent ye-organic reactions, ikakhulukazi ekuhlanganiseni kwezinhlanganisela ezihlukahlukene zezinto eziphilayo. Ikhono layo lokuncibilikisa uhla olubanzi lwezinto ezipholile nezingezona i-polar yenza kube usizo kakhulu kuzilungiselelo zaselabhorethri.
 
2. Ukukhipha kanye Nokwehlukanisa:I-TETRA-N-BUTYLUREA ingasetshenziswa ezinqubweni zokukhipha uketshezi oluwuketshezi ukuze kuhlukaniswe izinhlanganisela ngokusekelwe ekuncibilikeni kwazo. Isebenza kahle kakhulu ekukhipheni ama-ion ensimbi athile nezinhlanganisela eziphilayo ezixubeni.
 
3. Ama-reagents ekuphenduleni kwamakhemikhali:I-N,N,N',N'-Tetra-n-butylurea ingasetshenziswa njenge-reagent ekuphenduleni kwamakhemikhali okuhlukahlukene, okuhlanganisa ukusabela okubandakanya ukushintshwa kwe-nucleophilic nokunye ukuguqulwa kwezinto eziphilayo.
 
4. Inkampani yenethiwekhi ye-Catalyst:Ezinqubweni ezithile ze-catalytic, i-TBU ingasetshenziswa njengesiphathimandla se-catalyst ukuze kuthuthukiswe ukunyibilika kwayo nokusebenza kabusha kwingxube yokusabela.
 
5. Izicelo Zocwaningo:I-N,N,N',N'-TETRA-N-BUTYLUREA isetshenziswa ezindaweni zocwaningo, ikakhulukazi ucwaningo olubandakanya imiphumela yokuxazululwa, uketshezi lwe-ionic nezinye izinkambu ezibonakalayo namakhemikhali.
 
6. I-Polymer Chemistry:I-N,N,N',N'-tetrabutyl-;tetrabutyl-ure ingasetshenziswa kukhemistri ye-polymer futhi ingasetshenziswa njengesixazululi noma isithasiselo ekuhlanganiseni kwe-polymer.

Ungayigcina kanjani i-Tetrabutylurea?

I-Tetrabutylurea (TBU) kufanele igcinwe ngendlela efanele ukuze igcine ukuzinza kwayo futhi ivimbele noma yiziphi izingozi ezingaba khona. Nansi eminye imihlahlandlela yokugcina i-tetrabutylurea:
 
1. Isitsha:Gcina i-tetrabutyl urea esitsheni esivaliwe ukuze uvimbele ukungcoliswa nokuhwamuka. Isiqukathi kufanele senziwe ngezinto ezihambisana nezincibilikisi eziphilayo, njengengilazi noma amapulasitiki athile.
 
2. Izinga lokushisa:Gcina i-TBU endaweni epholile, eyomile ekude nelanga eliqondile nemithombo yokushisa. Ngokufanelekile, kufanele igcinwe ekamelweni lokushisa, kodwa izimo ezithile zokugcina zingancika ezincomo zomenzi.
 
3. Ukungenisa umoya:Qinisekisa ukuthi izindawo zokugcina zinomoya okahle ukuze unciphise ukunqwabelana kwanoma yimuphi umhwamuko ongase ukhishwe.
 
4. Hlukanisa nezinto ezingahambelani:Gcina i-tetrabutyl urea kude nama-oxidants aqinile, ama-asidi nezinye izinto ezingahambelani ukuze uvimbele noma yikuphi ukusabela okuyingozi.
 
5. Ilebula:Lebula ngokucacile iziqukathi ezinegama lekhemikhali, ukugxilisa ingqondo, ulwazi lwengozi, nosuku lokutholwa. Lokhu kusiza ukukhomba izinto futhi kuqinisekisa ukuphatha okuphephile.
 
6. Izinyathelo Zokuphepha:Landela yonke imihlahlandlela nemithetho yokuphepha yokugcina amakhemikhali efanelekile, okuhlanganisa naleyo ehlinzekwe isikhungo sakho noma imithetho yendawo.
 
7. Ukulahlwa:Uma i-Tetrabutyl Urea idinga ukulahlwa, sicela uhambisane nemithetho yendawo mayelana nokulahlwa kukadoti oyingozi.
 
Ngaso sonke isikhathi bheka I-Material Safety Data Sheet (MSDS) ye-Tetrabutyl Urea ukuze uthole izincomo ezithile zokugcinwa nokuphatha.

Izixwayiso ngesikhathi sokuthutha mayelana ne-Tetrabutylurea ?

Lapho uthutha i-tetrabutyl urea, kufanele kuthathwe izinyathelo ezithile zokuqapha ukuze kuqinisekiswe ukuphepha nokuhambisana nemithethonqubo. Okulandelayo ezinye izinto ezibalulekile okufanele zicatshangelwe ngesikhathi sokuthutha:
 
1. Ukuthobela Umthetho:Qinisekisa ukuthi ukuthunyelwa kuhambisana nemithetho yendawo, kazwelonke kanye neyamazwe ngamazwe mayelana nokuthuthwa kwezinto eziyingozi. Hlola ukuthi i-tetrabutyl urea ihlukaniswa njengento eyingozi futhi ulandele imihlahlandlela efanele.
 
2. Ukupakisha:Sebenzisa amaphakheji afanelekile ahambisana ne-tetrabutyl urea. Isiqukathi kufanele singavuzi futhi senziwe ngezinto ezikwazi ukumelana namakhemikhali e-TBU. Qinisekisa ukuthi ukupakisha kunamandla ngokwanele ukuvimbela umonakalo ngesikhathi sokuthutha.
 
3. Ilebula:Lebula ngokucacile iphakheji ngegama lekhemikhali, uphawu lwengozi, nanoma yiluphi ulwazi oluhlobene nokuphepha. Lokhu kuhlanganisa imiyalelo yokusingatha kanye nolwazi lokuxhumana oluphuthumayo.
 
4. Ukulawula izinga lokushisa:Uma kunesidingo, hambisa i-Tetrabutylrea ngaphansi kwezimo ezilawulwa izinga lokushisa ukuze uvimbele ukuwohloka noma izinguquko ezakhiweni. Gwema ukuchayeka emazingeni okushisa aphezulu.
 
5. Gwema Izinto Ezingahambelani:Qinisekisa ukuthi i-Tetrabutylurea ayithunyelwa kanye nezinto ezingahambelani njengama-oxidants aqinile noma ama-asidi ukuvimbela noma yikuphi ukusabela okungenzeka.
 
6. Izinto Zokuzivikela Zomuntu Siqu (PPE):Abasebenzi abahilelekile kwezokuthutha kufanele bagqoke i-PPE efanele, njengamagilavu, izibuko, nezingubo zokuzivikela ukuze banciphise ukuchayeka uma kwenzeka kuchitheka noma kuvuza.
 
7. Izinqubo Eziphuthumayo:Yakha izinqubo eziphuthumayo zokubhekana nokuchitheka noma izingozi ngesikhathi sokuthutha. Lokhu kuhlanganisa ukulungisa izinto zokuchitha amanzi kanye nezinto zosizo lokuqala.
