Isingeniso
I-3,5-difluorophenylhydrazine hydrochloride iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, indlela yokukhiqiza kanye nolwazi lokuphepha:
Izakhiwo: Iyancibilika emanzini nakwezinye izincibilikisi eziphilayo njenge-ethanol, i-methanol. Kuyinto ene-asidi ebuthakathaka ehlangana nama-alkali.
Sebenzisa:
I-3,5-difluorophenylhydrazine hydrochloride ivame ukusetshenziswa njenge-ejenti yokunciphisa kanye ne-activator ku-organic synthesis. Ingasetshenziselwa ukusabela okungeziwe, ukunciphisa izinhlanganisela eziphilayo ezifana nama-ketone, ama-aldehydes, ama-ketone anuka kamnandi, njll.
Indlela:
I-3,5-Difluorophenylhydrazine hydrochloride ingatholakala ngokusabela kwe-hydroquinone ne-2-chloro-1,3,5-trifluorobenzene. Ngokuvamile, i-hydroquinone isabela ngokwedlulele ku-2-chloro-1,3,5-trifluorobenzene ngaphansi kwezimo ze-alkaline ukuze ithole i-3,5-difluorophenylhydrazine. Ngokusabela nge-hydrogen chloride, i-3,5-difluorophenylhydrazine hydrochloride ingatholakala.
Ulwazi Lokuphepha:
I-3,5-Difluorophenylhydrazine hydrochloride iyikhemikhali evame ukusetshenziswa kumalabhorethri nokukhiqizwa kwezimboni. Imithetho efanele kufanele ilandelwe phakathi nenqubo, futhi izinto zokuzivikela ezifanele ezifana namagilavu, izibuko zokuphepha, namajazi elebhu kufanele kugqokwe. Ayinabuthi obuncane, kodwa kusafanele igwenywe ukuthintana nesikhumba, amehlo, nokuhogela. Esimeni sokuchayeka, kuyadingeka ukugeza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha. Ngesikhathi sokugcina, kufanele igcinwe kude nemithombo yomlilo kanye nezinto ezivuthayo, futhi igcinwe endaweni eyomile, enomoya omuhle.
