Nhanganyaya

Potassium borohydride is anorganic compound. Zvimiro zvayo ndezvizvi:

 

1. Kuonekwa: Potassium borohydride ichena crystalline powder kana granule.

 

3. Solubility: Potassium borohydride inonyungudika mumvura uye zvishoma nezvishoma inogadziriswa mumvura kuti ibudise hydrogen uye potassium hydroxide.

 

4. Yakananga giravhiti: Kuwanda kwe potassium borohydride inenge 1.1 g/cm³.

 

5. Kugadzikana: Mumamiriro ezvinhu akajairika, potassium borohydride inenge yakagadzikana, asi inogona kuora muhupo hwekushisa kwepamusoro, hunyoro hwepamusoro uye maoxidants ane simba.

 

Iko kushandiswa kukuru kwe potassium borohydride kunosanganisira:

 

1. Hydrogen source: Potassium borohydride inogona kushandiswa se reagent ye synthesis yehydrogen, iyo inogadzirwa nekuita nemvura.

 

2. Kemikari inoderedza mumiririri: potassium borohydride inogona kuderedza zvakasiyana-siyana zvemakomponi kuti aenderane nemakemikari akadai sedoro, aldehydes, uye ketones.

 

3. Metal pamusoro kurapwa: Potassium borohydride inogona kushandiswa electrolytic hydrogenation kurapwa kwesimbi nzvimbo kuderedza pamusoro oxides.

 

Nzira dzekugadzirira dze potassium borohydride dzinonyanya kusanganisira nzira yekudzikisa zvakananga, nzira ye antiborate uye nzira yekuderedza aluminium poda. Pakati pavo, iyo inonyanya kushandiswa nzira inowanikwa nekuita kwe sodium phenylborate uye hydrogen pasi pechiito che catalyst.

 

Ruzivo rwekuchengetedza potassium borohydride ndeichi:

 

1. Potassium borohydride ine simba reducibility, uye hydrogen inobudiswa painopindirana nemvura uye asidi, saka inoda kushandiswa munzvimbo ine mhepo yakanaka.

 

2. Dzivisa kusangana neganda, maziso, uye nzira yekufema kudzivirira kushatirwa nekukuvara.

 

3. Paunenge uchichengetedza uye uchishandisa potassium borohydride, kutarisirwa kunofanira kutorwa kudzivirira kusangana neoxidants nezvimwe zvinhu kudzivirira moto kana kuputika.

 

4. Usasanganise potassium borohydride nezvinhu zvine acidic kudzivirira kuumbwa kwemagasi ane ngozi.

 

5. Pakurasa potassium borohydride tsvina, mitemo yakakodzera yezvakatipoteredza uye yekuchengetedza inofanira kuteverwa.
