CAS No. 7637-7-2 Boron Fluoride Supplier. Cov yam ntxwv ntawm Boron Fluoride

Boron trifluoride (BF₃) yog ib qho tshuaj sib xyaw uas tau siv dav hauv kev lag luam tshuaj, tshwj xeeb tshaj yog ua cov catalyst hauv cov organic synthesis thiab ua cov tshuaj reagent hauv ntau yam tshuaj. CAS Nr .: 7637-7-2. Nov yog qee cov yam ntxwv tseem ceeb ntawm boron trifluoride:

Lub cev muaj zog:
Cov tsos mob: tsis muaj xim tsis muaj roj raws li tus qauv.
Kub taw tes: -100.3 ° C (-148.5 ° F).
Melting Point: -127.2 ° C (-196.9 ° F).
Qhov ceev: 2.88 g / L ntawm 20 ° C.
Solubility hauv dej: Soluble, tab sis nws reacts nrog dej los tsim boric acid thiab hydrofluoric acid.
Chemical Properties:
Reactivity: Reactive heev, tshwj xeeb tshaj yog nrog dej, cawv, thiab lwm yam nucleophiles.
Acidity: BF₃ ua raws li Lewis acid vim nws cov electron-tsis muaj boron atom.
Toxicity: Nws tuaj yeem tsim kev puas tsuaj yog tias nqus tau, nqos, lossis kis rau ntawm daim tawv nqaij lossis qhov muag. Nws yog corrosive thiab tuaj yeem ua rau kub hnyiab heev.
Kev siv:
Catalysis: Feem ntau siv los ua ib qho catalyst hauv Friedel-Crafts cov tshuaj tiv thaiv thiab lwm yam kev cuam tshuam cov organic synthesis.
Etching Agent: Siv nyob rau hauv semiconductor manufacturing rau etching silicon dioxide.
Fluorination Reactions: Siv rau hauv kev npaj cov tshuaj fluorinated.
Analytical Chemistry: Siv nyob rau hauv roj chromatography ua ib tug reagent rau derivatization ntawm amines.
Thaum tuav boron trifluoride, kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua vim nws cov tshuaj toxicity thiab reactivity. Qhov no suav nrog kev siv cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab daim npog ntsej muag, ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo lossis lub hood fume, thiab ua raws li tag nrho cov lus qhia txog kev nyab xeeb.
