Aluminium borohydride(CAS#16962-07-5)

Mawu Oyamba

Aluminiyamu borohydride ndi pawiri wosakhazikika. Lili ndi zotsatirazi:

1. Zakuthupi: Aluminium borohydride ndi yolimba yopanda mtundu, nthawi zambiri imakhala ngati ufa. Ndi yosakhazikika kutentha kwa chipinda ndipo imayenera kusungidwa ndi kusamalidwa pamalo otsika komanso mpweya wa mpweya.

2. Chemical katundu: Aluminiyamu borohydride akhoza kuchita ndi zidulo, alcohols, ketoni ndi mankhwala ena kupanga lolingana mankhwala. Kuchita zachiwawa kumachitika m'madzi kuti apange haidrojeni ndi aluminium acid hydride.

Ntchito zazikulu za aluminium borohydride ndi izi:

1. Monga chochepetsera: Aluminium borohydride ili ndi mphamvu zochepetsera, ndipo nthawi zambiri imagwiritsidwa ntchito ngati chochepetsera mu kaphatikizidwe ka organic. Ikhoza kuchepetsa zinthu monga aldehydes, ketones, etc., ku ma alcohols ofanana.

2. Kugwiritsa ntchito kafukufuku wa sayansi: Aluminiyamu borohydride ili ndi phindu lofufuza pamtundu wa organic synthesis ndi catalysis, ndipo ingagwiritsidwe ntchito popanga mankhwala atsopano ndi kulimbikitsa machitidwe.

Pali njira ziwiri zokonzekera aluminium borohydride:

1. Zomwe zimachitika pakati pa aluminium hydroxide ndi trimethylboron: trimethylboron imasungunuka mu njira ya ethanol ya aluminium hydroxide, mpweya wa haidrojeni umayambitsidwa kuti upeze aluminium borohydride.

2. Kuchita kwa alumina ndi dimethylborohydride: sodium dimethylborohydride ndi alumina amatenthedwa ndikuchitapo kanthu kuti apeze aluminium borohydride.

Mukamagwiritsa ntchito aluminium borohydride, mfundo zotsatirazi zachitetezo ziyenera kudziwidwa:

1. Aluminiyamu borohydride imakhala ndi mphamvu yochepetsetsa, ndipo imachita mwachiwawa ikakumana ndi madzi, asidi ndi zinthu zina, kutulutsa mpweya woyaka ndi mpweya wapoizoni. Magalasi oteteza, magolovesi ndi zovala zodzitchinjiriza ziyenera kuvala panthawi yogwira ntchito.

2. Aluminium borohydride iyenera kusungidwa pamalo owuma, osindikizidwa, ndi amdima, kutali ndi moto ndi zipangizo zoyaka moto.

3. Kulowa munjira yopuma kapena pakhungu kumatha kuvulaza kwambiri ndipo kuyenera kupewedwa pokoka mpweya ndi kukhudza. Mukakhudzana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
