Hordhac

Potassium borohydride waa unug aan organic ahayn. Astaanteedu waa sida soo socota:

 

1. Muuqashada: Potassium borohydride waa budo crystalline cad ama granule.

 

3. Solubility: Potassium borohydride waxa ay ku milmaysaa biyaha oo si tartiib tartiib ah ayaa biyo loogu shubaa si ay u soo saarto hydrogen iyo potassium hydroxide.

 

4. Cuf-jiid gaar ah: cufnaanta borohydride potassium waa qiyaastii 1.1 g/cm³.

 

5. Xasilooni: Xaaladaha caadiga ah, borohydride potassium waa mid deggan, laakiin waxa laga yaabaa inay qudhunto joogitaanka heerkulka sare, huurka sarreeya iyo oksidayaasha xooggan.

 

Isticmaalka ugu muhiimsan ee borohydride potassium waxaa ka mid ah:

 

1. Isha Hydrogen: Potassium borohydride waxa loo isticmaali karaa reagent ka samaysan hydrogen, kaas oo lagu soo saaro falcelinta biyaha.

 

2. Kiimikada yaraynaysaa: borohydride potassium waxay yarayn kartaa isku-dhisyada kala duwan ee iskudhisyada organic u dhigma sida khamriga, aldehyde, iyo ketones.

 

3. Daaweynta dusha birta ah: Potassium borohydride waxaa loo isticmaali karaa daaweynta hydrogenation electrolytic ee sagxadaha birta si loo yareeyo oksaydhyada dusha sare.

 

Habka diyaarinta borohydride potassium inta badan waxaa ka mid ah habka dhimista tooska ah, habka antiborate iyo habka dhimista budada aluminium. Waxaa ka mid ah, habka ugu badan ee la isticmaalo waxaa lagu helaa falcelinta sodium phenylborate iyo hydrogen oo hoos yimaada ficilka kicinta.

 

Macluumaadka badbaadada ee borohydride potassium waa sida soo socota:

 

1. Potassium borohydride waxa ay leedahay dib-u-dhis xoog leh, hydrogen waxa ay soo saartaa marka ay la falgasho biyo iyo aashito, sidaa awgeed waxa ay u baahan tahay in lagu qalo meel hawo fiican leh.

 

2. Ka fogow taabashada maqaarka, indhaha, iyo marinnada neefsashada si aad uga hortagto xanaaq iyo dhaawac.

 

3. Marka la kaydinayo oo la isticmaalayo potassium borohydride, waa in laga taxadaro si looga hortago taabashada oksaydhiyeyaasha iyo walxaha kale si looga hortago dabka ama qaraxa.

 

4. Ha isku darin borohydride potassium iyo walxaha acidic si aad isaga ilaaliso samaynta gaasaska khatarta ah.

 

5. Marka la tuurayo qashinka borohydride potassium, waa in la raaco xeerarka deegaanka iyo badbaadada ee khuseeya.
