Inombolo ye-CAS 7637-7-2 Boron Fluoride Supplier. Iimpawu zeBoron Fluoride
I-Boron trifluoride (BF₃) yikhompawundi yeekhemikhali esetyenziswa kakhulu kwishishini lemichiza, ngakumbi njenge-catalyst kwi-organic synthesis kunye ne-reagent kwi-reagents yeekhemikhali ezahlukeneyo. Inenombolo yeCAS 7637-7-2. Nazi ezinye iimpawu eziphambili ze-boron trifluoride:
Iinkcazelo Ngeempawu:
Ukubonakala: Igesi engenambala phantsi kweemeko eziqhelekileyo.
Indawo yokuBilisa: -100.3°C (-148.5°F).
Indawo yokunyibilika: -127.2°C (-196.9°F).
Ubuninzi: 2.88 g/L ku-20°C.
Ukunyibilika emanzini: Inyibilika, kodwa idibana namanzi ukwenza i-boric acid kunye ne-hydrofluoric acid.
Iinkcazelo ngeMichiza:
Ukusebenza kwakhona: Isebenza kakhulu, ngakumbi ngamanzi, i-alcohols, kunye nezinye iinucleophiles.
I-Acidity: I-BF₃ isebenza njenge-asidi ye-Lewis ngenxa ye-athomu ye-boron engenambane.
Ubutyhefu: Inokuba yingozi xa irholiwe, iginywe, okanye idibane nolusu okanye amehlo. Inomhlwa kwaye inokubangela ukutshisa okukhulu.
Usebenzisa:
I-Catalysis: Idla ngokusetyenziswa njenge-catalyst kwi-reactions ye-Friedel-Crafts kunye nezinye iimpendulo ze-organic synthesis.
I-Etching Agent: Isetyenziswa kwimveliso ye-semiconductor yokufaka isilicon dioxide.
I-Fluorination Reactions: Isetyenziselwa ukulungiswa kwee-fluorinated compounds.
I-Analytical Chemistry: Isetyenziswa kwi-chromatography yegesi njenge-reagent yokukhupha ii-amines.
Xa uphatha i-boron trifluoride, amanyathelo afanelekileyo okhuseleko kufuneka athathwe ngenxa yetyhefu kunye nokusebenza kwakhona. Oku kuquka ukusebenzisa izixhobo zokuzikhusela ezifana neeglavu, iiglavu, ikhuselo lobuso, ukusebenza kwindawo engena umoya okanye ifume hood, kunye nokulandela zonke izikhokelo zokhuseleko ezifanelekileyo.
