Isingeniso
I-O-bromophenylhydrazine hydrochloride. Izici zayo zimi kanje:
1. Ukubukeka: I-O-bromophenylhydrazine hydrochloride iyimpushana yecrystalline ekhanyayo engenambala ukuya kokuphuzi.
2. Ukunyibilika: kuncibilika emanzini, i-ethanol ne-chloroform, inyibilika kancane ku-ether.
3. Ukuzinza: Azinzile uma kuqhathaniswa nezinga lokushisa legumbi, futhi kulula ukubola lapho kuvezwe ukukhanya, izinga lokushisa eliphezulu kanye ne-oxidant.
4. Ukusabela kwamakhemikhali: i-o-bromophenylhydrazine hydrochloride ingasabela ngama-ion e-copper(II) ukuze yenze imvula ebomvu ngokubomvu noma ensundu.
Ukusetshenziswa okuyinhloko kwe-o-bromophenazine hydrochloride imi kanje:
1. I-Chemical reagent: i-o-bromophenazine hydrochloride ingasetshenziswa njenge-ejenti yokunciphisa, i-reagent yokuxhumanisa kanye nempahla eluhlaza ye-organic synthesis.
2. Izicelo ze-Electrochemical: i-o-bromophenylhydrazine hydrochloride ingasetshenziselwa ukuhlaziywa kwe-electrochemical namabhethri.
Indlela yokulungiselela i-o-bromophenylhydrazine hydrochloride:
Ukulungiswa kwe-o-bromophenylhydrazine hydrochloride ngokuvamile kutholakala ngokusabela kwe-bromophenylhydrazine nge-hydrochloric acid. Ku-solvent efanele, i-bromophenylhydrazine imisiwe ku-acetic acid, bese i-hydrochloric acid egxilile yengezwa kancane kancane, futhi imvula itholakala ngemva kokusabela, futhi i-o-bromophenylhydrazine hydrochloride ingatholakala ngemva kokumisa, i-crystallization nezinye izinyathelo.
Ulwazi Lokuphepha:
1. I-O-bromophenylhydrazine hydrochloride idinga izinyathelo zokugwema ukuthintana nesikhumba namehlo ngesikhathi sokuphatha nokugcinwa. Uma kwenzeka ukuthintana ngephutha, hlambulula ngokushesha ngamanzi.
2. Gwema ukuhogela umhwamuko wothuli lwawo noma isisombululo ngesikhathi sokusebenza ukuze ugweme ukungaphatheki kahle kokuphefumula.
3. Gwema ukuthinta izinto ezivuthayo nama-oxidants ukuze ugweme umlilo noma ukuqhuma.
4. Imfucuza kufanele ilahlwe ngokuhambisana nemithetho yendawo, futhi kwenqatshelwe ukulahlwa noma ukuchithwa endaweni ngokuthanda kwayo.
