I-Methyl 5-bromo-2-chlorobenzoate (CAS# 251085-87-7)
Isingeniso
I-methyl 5-bromo-2-chlorobenzoate iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-ifomula yamakhemikhali: C8H6BrClO2
Isisindo samangqamuzana: 241.49g/mol
-Ukubukeka: Ayinambala ukuya kokuqinile okuphuzi kancane
-Indawo yokuncibilika: 54-57 ° C
-Indawo yokubilisa: 306-309 ° C
-Ukuncibilika okuphansi emanzini
Sebenzisa:
I-methyl 5-bromo-2-chlorobenzoate ivamise ukusetshenziswa njengendawo emaphakathi ku-organic synthesis futhi ingasetshenziswa ukuze kuhlanganiswe izinhlanganisela ezisebenza ngokwebhayoloji. Ingasetshenziswa njengesiqalo sokuhlanganiswa kwezidakamizwa, izibulala-zinambuzane kanye nodayi, futhi ingasetshenziswa ekuphenduleni esikhundleni, ukusabela kwe-tandem kanye nokusabela kwe-aromatization ekuphenduleni kwe-organic synthesis.
Indlela:
I-methyl 5-bromo-2-chlorobenzoate ingalungiswa ngokusabela ukumiswa kwe-methyl benzoate nge-bromine lapho kukhona i-ferrous chloride. Okokuqala, i-methyl benzoate yaxutshwa ne-ferrous chloride solution, yengezwa i-bromine, futhi ingxube yanyakaziswa ekushiseni okuvamile. Ngemuva kokusabela, umkhiqizo ohlosiwe we-methyl 5-bromo-2-chlorobenzoate watholwa ngokwelashwa kwenqubo ye-acidic kanye nokuhlanzwa kwecrystallization.
Ulwazi Lokuphepha:
- I-methyl 5-bromo-2-chlorobenzoate iyinhlanganisela yezinto eziphilayo futhi kufanele isingathwe ngokucophelela ukugwema ukuthintana ngqo nesikhumba kanye nokuhogela.
-Gqoka izinto zokuzivikela ezifana namagilavu lab, izibuko kanye namajazi elebhu lapho usebenza.
-Lapho uyigcina, yigcine esitsheni esipholile, esomile nesivalekile, kude nomlilo kanye nama-oxidizing agents.
-Sicela ulandele indlela yendawo yokwelapha imfucuza yamakhemikhali lapho ulahla ukuze ugweme ukungcoliswa kwemvelo.
-Uma usebenzisa noma uphatha inhlanganisela, sicela ubheke imibhalo efanele yokuphepha kanye neziyalezo zokusebenza, futhi ulandele izinqubo ezilungile zokusebenza zokuphepha zaselabhorethri.
