Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
I-R22 – Iyingozi uma igwinywe
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
Inothi Lengozi Iyacasula

 

Isingeniso

I-2,2-Difluoro-1, i-asidi iyinhlanganisela yezinto eziphilayo. Nalu olunye ulwazi ngakho:

 

Izakhiwo: 2,2-Difluoro-1, i-fluorid iqinile emhlophe. Ifomula yayo yamangqamuzana ithi C9H4F2O4 futhi isisindo sayo samangqamuzana ngu-200.12g/mol. Iyazinzile ekamelweni lokushisa futhi inokuncibilika okuphansi.

 

Ukusetshenziswa: 2,2-Difluoro-1, isetshenziswa njengento eluhlaza kanye ne-reagent ocwaningweni lwamakhemikhali kanye nokuhlanganiswa kwe-organic. Ingasetshenziselwa ukuhlanganisa ezinye izinhlanganisela eziphilayo, njengemithi ephakathi kwemithi, izibulala-zinambuzane kanye nodayi.

 

indlela yokulungiselela: 2,2-Difluoro-1, indlela yokulungiselela i-asidi iyinkimbinkimbi kakhulu. Indlela evame ukusetshenziswa yokulungiselela itholakala nge-oxidation ye-benzodioxene, elandelwa ukusabela nge-agent fluorinating ngaphansi kwezimo ezifanele ukwethula i-athomu ye-fluorine.

 

Ulwazi lokuphepha: Okwamanje, kunolwazi olulinganiselwe lokuphepha mayelana ne-2,2-Difluoro-1, i-UV acid. Akuzange kufundwe kabanzi, ngakho-ke ubuthi bayo kanye nengozi akuqondakali kahle. Ngesikhathi sokusetshenziswa, kuyadingeka ukulandela izinqubo zokuphepha zaselabhorethri yamakhemikhali jikelele ukuze kuqinisekiswe ukusebenza okuphephile, futhi ugweme ukuhogela, ukuthintana nesikhumba namehlo. Ngaphambi kokusetshenziswa, kunconywa ukuthi uqonde ishidi ledatha yezokuphepha ye-compound ngokuningiliziwe futhi uthathe izinyathelo zokuzivikela ezifanele ngokusekelwe ekuhloleni kwayo ingozi.

  • Okwedlule:

    • Bhala umyalezo wakho lapha futhi usithumelele wona
