CAS No. 7637-7-2 Boron Fluoride Supplier. Izici ze-Boron Fluoride

I-Boron trifluoride (BF₃) iyinhlanganisela yamakhemikhali esetshenziswa kabanzi embonini yamakhemikhali, ikakhulukazi njenge-catalyst in organic synthesis futhi njenge-reagent ekuphenduleni kwamakhemikhali okuhlukahlukene. Inenombolo ye-CAS 7637-7-2. Nazi ezinye izici ezibalulekile ze-boron trifluoride:

Izakhiwo Zomzimba:
Ukubukeka: Igesi engenambala ngaphansi kwezimo ezijwayelekile.
Indawo yokubilisa: -100.3°C (-148.5°F).
Indawo Encibilika: -127.2°C (-196.9°F).
Ukuminyana: 2.88 g/L ku-20°C.
Ukunyibilika Emanzini: Kuyancibilika, kodwa kuhlangana namanzi ukwenza i-boric acid ne-hydrofluoric acid.
Izakhiwo Zekhemikhali:
Ukusebenza kabusha: Kusebenza kakhulu, ikakhulukazi ngamanzi, utshwala, namanye ama-nucleophile.
I-Acidity: I-BF₃ isebenza njenge-Lewis acid ngenxa ye-athomu ye-boron engenawo ama-electron.
Ubuthi: Kungaba yingozi uma uhogela, ugwinywa, noma uthinta isikhumba noma amehlo. Iyagqwala futhi ingabangela ukusha okukhulu.
Isebenzisa:
I-Catalysis: Ivamise ukusetshenziswa njenge-catalyst ku-Friedel-Crafts reactions nokunye ukusabela kokwenziwa kwe-organic.
I-Etching Agent: Isetshenziswa ekwenziweni kwe-semiconductor yokufaka i-silicon dioxide.
Ukusabela kwe-Fluorination: Kusetshenziswa ekulungiseleleni ama-fluorinated compounds.
I-Analytical Chemistry: Isetshenziswa ku-chromatography yegesi njenge-reagent yokukhipha ama-amine.
Lapho kusingathwa i-boron trifluoride, izinyathelo zokuphepha ezifanele kufanele zithathwe ngenxa yobuthi bayo kanye nokusebenza kabusha. Lokhu kuhlanganisa ukusebenzisa izinto zokuzivikela ezifana namagilavu, izibuko, nesivikelo sobuso, ukusebenza endaweni enomoya omuhle noma i-fume hood, kanye nokulandela yonke imihlahlandlela yokuphepha efanele.
