I-Aluminium borohydride(CAS#16962-07-5)

Isingeniso

I-Aluminium borohydride iyinhlanganisela ye-inorganic. Inezici ezilandelayo:

1. Izakhiwo zomzimba: I-Aluminium borohydride iqinile engenambala, ngokuvamile iyimpushana. Ayizinzile kakhulu kumazinga okushisa asekamelweni futhi kufanele igcinwe futhi isingathwe endaweni ephansi yokushisa kanye negesi engasebenzi.

2. Izakhiwo zamakhemikhali: I-Aluminium borohydride ingasabela ngama-acids, utshwala, ama-ketones nezinye izinhlanganisela ukwenza imikhiqizo ehambisanayo. Ukusabela okunobudlova kwenzeka emanzini ukuze kukhiqizwe i-hydrogen ne-aluminic acid hydride.

Ukusetshenziswa okuyinhloko kwe-aluminium borohydride kuhlanganisa:

1. Njenge-ejenti yokunciphisa: I-Aluminium borohydride inezinto eziqinile zokunciphisa, futhi ivame ukusetshenziswa njenge-ejenti yokunciphisa ku-organic synthesis. Inganciphisa izinhlanganisela ezifana ne-aldehydes, ketones, njll., kuma-alcohols ahambisanayo.

2. Ukusetshenziswa kocwaningo lwesayensi: I-Aluminium borohydride inenani elibalulekile locwaningo emkhakheni we-organic synthesis kanye ne-catalysis, futhi ingasetshenziswa ukuhlanganisa izinhlanganisela ezintsha ze-organic kanye nokwenza ukusabela.

Ngokuvamile kunezindlela ezimbili zokulungiselela i-aluminium borohydride:

1. Ukusabela phakathi kwe-aluminium hydroxide ne-trimethylboron: i-trimethylboron ichithwa kusisombululo se-ethanol se-aluminium hydroxide, igesi ye-hydrogen yethulwa ukuthola i-aluminium borohydride.

2. Ukusabela kwe-alumina ne-dimethylborohydride: i-sodium dimethylborohydride ne-alumina ziyashiswa futhi ziyasabela ukuze zithole i-aluminium borohydride.

Uma usebenzisa i-aluminium borohydride, ulwazi olulandelayo lokuphepha kufanele luqashelwe:

1. I-Aluminium borohydride inokuncipha okuqinile, futhi izosabela ngobudlova lapho ithintana namanzi, i-asidi nezinye izinto, ikhiqize igesi evuthayo namagesi anobuthi. Izibuko zokuzivikela, amagilavu ​​nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza.

2. I-Aluminium borohydride kufanele igcinwe endaweni eyomile, evalekile, futhi emnyama, kude nomlilo nezinto ezivuthayo.

3. Ukuhlasela komgudu wokuphefumula noma isikhumba kungabangela ukulimala okukhulu futhi kufanele kugwenywe ukuze uhogele futhi uthintene. Uma uthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
