Aluminium borohydride (CAS # 16962-07-5)

Taw qhia

Aluminium borohydride yog ib qho inorganic compound. Nws muaj cov khoom nram qab no:

1. Cov khoom siv lub cev: Aluminium borohydride yog cov khoom tsis muaj xim, feem ntau yog hmoov. Nws tsis ruaj tsis khov heev ntawm chav tsev kub thiab yuav tsum tau muab khaws cia thiab ua haujlwm nyob rau hauv qhov kub thiab txias thiab inert gas ib puag ncig.

2. Cov khoom siv tshuaj lom neeg: Aluminium borohydride tuaj yeem ua rau cov kua qaub, cawv, ketones thiab lwm yam sib xyaw ua ke los tsim cov khoom sib xws. Cov tshuaj tiv thaiv hnyav tshwm sim hauv dej los tsim cov hydrogen thiab aluminic acid hydride.

Kev siv tseem ceeb ntawm aluminium borohydride suav nrog:

1. Raws li tus neeg sawv cev txo qis: Aluminium borohydride muaj zog txo cov khoom, thiab nws feem ntau yog siv los ua tus neeg sawv cev txo qis hauv cov organic synthesis. Nws tuaj yeem txo cov tebchaw xws li aldehydes, ketones, thiab lwm yam, rau cov cawv sib xws.

2. Kev tshawb fawb siv: Aluminium borohydride muaj txiaj ntsig tseem ceeb hauv kev tshawb fawb ntawm cov organic synthesis thiab catalysis, thiab tuaj yeem siv los tsim cov organic tebchaw tshiab thiab cov tshuaj tiv thaiv catalyze.

Feem ntau muaj ob txoj kev npaj rau txhuas borohydride:

1. Cov tshuaj tiv thaiv ntawm aluminium hydroxide thiab trimethylboron: trimethylboron yog yaj nyob rau hauv ethanol tov ntawm aluminium hydroxide, hydrogen gas yog qhia kom tau txais aluminium borohydride.

2. Cov tshuaj tiv thaiv ntawm alumina thiab dimethylborohydride: sodium dimethylborohydride thiab alumina yog rhuab thiab reacted kom tau txais txhuas borohydride.

Thaum siv aluminium borohydride, cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum raug sau tseg:

1. Aluminium borohydride muaj zog txo qis, thiab yuav hnov ​​​​mob hnyav thaum nyob rau hauv kev sib cuag nrog dej, kua qaub thiab lwm yam khoom, ua rau combustible gases thiab toxic gases. Cov tsom iav tiv thaiv, hnab looj tes thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm.

2. Aluminium borohydride yuav tsum tau muab cia rau hauv qhov chaw qhuav, kaw, thiab qhov chaw tsaus, kom deb ntawm cov hluav taws kub thiab cov khoom siv hluav taws xob.

3. Kev ntxeem tau ntawm lub ntsws los yog daim tawv nqaij tuaj yeem ua rau muaj kev phom sij loj thiab yuav tsum zam kom tsis txhob nqus tau thiab tiv tauj. Nyob rau hauv rooj plaub ntawm kev sib chwv, yaug tam sim ntawd nrog dej ntau thiab nrhiav kev kho mob.
