I. Umgangatho wobungcali, ukhetho lwe-chemistry - n - n - i-bromosuccifinimilide (Nbs)

Kwintsimi enkulu ye-chemistry, ukufumana i-redage efanelekileyo nenokuthenjwa yeyona nto iphambili kuphando lwezenzululwazi kunye nemveliso yemveliso. N - I-bromosuccimilide (Nbs), ngokusebenza kwayo okubalaseleyo kunye nokusetyenziswa ngokubanzi, iye yaba lukhetho lokuqala kwiingcinezelo ezininzi zemichiza.

II. Iipropathi ezizodwa, ezikhokelela kumda we-chemistry

-Ukuthatha ukuthengiswa kwentsholongwane echazayo: i-NBS yiarhente ebalulekileyo ebuthathaka kwi-ornthesic synthesis. Kumzi-mveliso wamayeza, kudla ngokusetyenziswa njengearhente ebuthathaka kwi-synthesics, ezinjengeSynthesis kaBenzylin. Nokuba ngaba ngumhlaza we-Olefins okanye i-oxidation ye-aldehydes ukuya kwi-bromo-Acids, inokudlala indima echanekileyo, ibonelela ngesiqinisekiso esiqinisekileyo sendlela yakho yeSynthesis.

-Umncedisi onamandla wokuchonga iprayimari, i-tericary, ne-teager echongiweyo ichonge i-clarity, i-tericary, i-tericari, i-NBS, inika isiseko esikhethekileyo sohlalutyo lweekhephu.

I-Watch Oxidition: kwimpendulo ye-oxidation ye-tryptophan, i-NBS inokudlala indima esebenzayo, ngelixa i-oxidation yenqanaba le-tyrosine, ihilidine, kunye neentsalela zeMethionine zinokuthobeka. Kwangelo xesha, inokusetyenziselwa ukutshintsha kwamaqela e-Ribosomal, ukubonelela ngezixhobo ezintsha zophando lwesayensi loBomi.

III. Ulawulo olusemgangathweni olungqongqo, lukhuselekile kwaye luthembekile

-Izinto eziphezulu eziphezulu - sisebenzisa izinto eziphezulu eziphezulu kunye neenkqubo zokuvelisa ezingqongqo ukuqinisekisa ubunyulu kunye nokuzinza kwe-NBS.

-Ukugcinwa ngokukhuselekileyo: I-NBS inomdla wokufuma. Sicebisa ukuba ayigcine kwifriji ukuqinisekisa ukuba intsebenzo yayo ayichaphazelekanga. Kwangelo xesha, kufuneka igcinwe ngokwahlukeneyo ukusuka kwi-Aliline, i-Daykyl Sulfide, Hydrazine Hydrate, Peroxide, kunye ne-propuisomitrithurle ukunqanda ukuphendula okuyingozi.

-Ukusebenza ngokukhuselekileyo: Ngexesha lenkqubo yokusetyenziswa, ukuphefumla okanye ukunxibelelana nolusu kufuneka kuthintelwe. Ngokubanzi, ukusebenza kufuneka kwenziwe kwi-hood ye-sume ngentsebenzo elungileyo yokuphumelela kwi-ventilation yokuqinisekisa ukhuseleko lwakho lwakho.

Iv. Uluhlu olubanzi lwezicelo, ukuhlangabezana neemfuno ezahlukeneyo

-Ummandla wezonyango: Kumzi-mveliso wezamayeza, i-NBS ayisetyenziswanga kuphela kwi-synthesis ye-antibiotics kodwa ikwanokusetyenziselwa ukuqesha amachiza anje nge-bromocetotiittile, enegalelo kwimpembelelo yempilo yabantu.

-Ishishini lokubulala izitshabalalisi: isetyenziselwa ukuhlengahlengisa izifo ezinamayeza anje ngeTliabenda -le, ukuthintela nokulawula izifo zesifo kunye nezinambuzane kunye nokuphucula ukusebenza kwemveliso yezolimo.

-Ulondolozo lweziqhamo, i-anticorrosion, kunye ne-antifungal: inokusetyenziswa njengesixhobo sokugcina iziqhamo, kunye ne-antiForrosion kunye ne-antiFikorrosion kunye ne-antiFikorion kunye ne-antiFikorion kunye ne-AntiFifungal Arhente yeZiqhamo kunye nokuqinisekisa ukhuseleko lokutya.

Ukukhetha n - i-bromosuccifinimilide (i-NBS) kuthetha ukukhetha ubungcali, obufanelekileyo, kunye nokukhuseleka kwemichiza. Masisebenze kunye ukwenza ikamva elihle kwicandelo le-chemistry!
