Mawu Oyamba
Potaziyamu borohydride ndi mankhwala osakhazikika. Makhalidwe ake ndi awa:
1. Maonekedwe: Potaziyamu borohydride ndi ufa wa crystalline woyera kapena granule.
3. Kusungunuka: Potaziyamu borohydride imasungunuka m'madzi ndipo pang'onopang'ono imasungunuka m'madzi kupanga haidrojeni ndi potaziyamu hydroxide.
4. Kukoka kwapadera: Kuchuluka kwa potaziyamu borohydride ndi pafupifupi 1.1 g/cm³.
5. Kukhazikika: Pazinthu zodziwika bwino, potaziyamu borohydride imakhala yokhazikika, koma imatha kuwola pakakhala kutentha kwakukulu, chinyezi chambiri komanso ma oxidants amphamvu.
Ntchito zazikulu za potaziyamu borohydride ndi izi:
1. Gwero la haidrojeni: Potaziyamu borohydride ikhoza kugwiritsidwa ntchito ngati reagent pakupanga kwa hydrogen, yomwe imapangidwa pochita ndi madzi.
2. Mankhwala ochepetsera mankhwala: borohydride ya potaziyamu ikhoza kuchepetsa mitundu yosiyanasiyana ya mankhwala kuti agwirizane ndi mankhwala monga ma alcohols, aldehydes, ndi ketoni.
3. Zitsulo pamwamba mankhwala: Potaziyamu borohydride angagwiritsidwe ntchito electrolytic hydrogenation mankhwala a pamalo zitsulo kuchepetsa oxides padziko.
Njira zokonzekera potaziyamu borohydride makamaka zimaphatikizapo njira yochepetsera mwachindunji, njira ya antiborate ndi njira yochepetsera ufa wa aluminium. Pakati pawo, njira yomwe imagwiritsidwa ntchito kwambiri imapezeka ndi sodium phenylborate ndi hydrogen pansi pa chothandizira.
Chidziwitso chachitetezo cha potassium borohydride ndi motere:
1. Potaziyamu borohydride imakhala ndi mphamvu yochepetsetsa kwambiri, ndipo haidrojeni imapangidwa pamene imagwirizana ndi madzi ndi asidi, choncho iyenera kugwiritsidwa ntchito pamalo abwino mpweya wabwino.
2. Pewani kukhudzana ndi khungu, maso, ndi thirakiti la kupuma kuti mupewe kupsa mtima ndi kuvulala.
3. Posunga ndi kugwiritsa ntchito potaziyamu borohydride, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi okosijeni ndi zinthu zina kuti muteteze moto kapena kuphulika.
4. Osasakaniza potaziyamu borohydride ndi zinthu za acidic kuti apewe kupanga mpweya wowopsa.
5. Potaya zinyalala za potaziyamu borohydride, malamulo okhudzana ndi chilengedwe ndi chitetezo ayenera kutsatiridwa.
