Isingeniso
I-Potassium borohydride iyinhlanganisela ye-inorganic. Izici zayo zimi kanje:
1. Ukubukeka: I-Potassium borohydride iyimpushana yekristalu emhlophe noma i-granule.
3. Ukunyibilika: I-Potassium borohydride iyancibilika emanzini futhi kancane kancane i-hydrolyzed emanzini ukuze ikhiqize i-hydrogen ne-potassium hydroxide.
4. Amandla adonsela phansi athile: Ukuminyana kwe-potassium borohydride cishe ku-1.1 g/cm³.
5. Ukuzinza: Ngaphansi kwezimo ezivamile, i-potassium borohydride izinzile, kodwa ingase ibole lapho kukhona izinga lokushisa eliphezulu, umswakama ophezulu kanye nama-oxidants aqinile.
Ukusetshenziswa okuyinhloko kwe-potassium borohydride kuhlanganisa:
1. Umthombo we-Hydrogen: I-Potassium borohydride ingasetshenziswa njenge-reagent yokuhlanganiswa kwe-hydrogen, ekhiqizwa ngokuphendula ngamanzi.
2. I-ejenti yokunciphisa amakhemikhali: I-borohydride ye-potassium inganciphisa izinhlobonhlobo zezinhlanganisela ezihambisanayo ezifana ne-alcohols, aldehydes, nama-ketones.
3. Ukwelashwa kwensimbi yensimbi: I-Potassium borohydride ingasetshenziselwa ukwelashwa kwe-electrolytic hydrogenation yezindawo zensimbi ukunciphisa ama-oxide angaphezulu.
Izindlela zokulungiselela ze-potassium borohydride ikakhulukazi zihlanganisa indlela yokunciphisa ngokuqondile, indlela ye-antiborate kanye nendlela yokunciphisa i-aluminium powder. Phakathi kwazo, indlela evame ukusetshenziswa kakhulu itholakala ngokusabela kwe-sodium phenylborate ne-hydrogen ngaphansi kwesenzo se-catalyst.
Imininingwane yokuphepha ye-potassium borohydride imi kanje:
1. I-Potassium borohydride inokuncibilika okuqinile, futhi i-hydrogen ikhiqizwa lapho ihlangana namanzi ne-asidi, ngakho idinga ukusebenza endaweni enomoya omuhle.
2. Gwema ukuthinta isikhumba, amehlo, nemigudu yokuphefumula ukuze uvimbele ukucasuka nokulimala.
3. Lapho ugcina futhi usebenzisa i-potassium borohydride, kufanele kuqashelwe ukuvimbela ukuthintana nama-oxidants nezinye izinto ukuvimbela umlilo noma ukuqhuma.
4. Ungaxubi i-potassium borohydride nezinto ezine-asidi ukuze ugweme ukwakheka kwamagesi ayingozi.
5. Lapho kulahlwa udoti we-potassium borohydride, kufanele kulandelwe imithetho efanele yezemvelo nezokuphepha.
