Hoʻolauna
ʻO ka potassium borohydride he mea hoʻohuihui ʻole. Penei kona mau waiwai.
1. Nānā: ʻO ka potassium borohydride ka pauka keʻokeʻo keʻokeʻo a i ʻole granule.
3. Solubility: Hiki ke hoʻoheheʻe ʻia ka potassium borohydride i ka wai a hoʻoheheʻe ʻia i loko o ka wai e hana i ka hydrogen a me ka potassium hydroxide.
4. Kaumaha kikoʻī: ʻO ka nui o ka potassium borohydride ma kahi o 1.1 g / cm³.
5. Paʻa: Ma lalo o nā kūlana maʻamau, paʻa paʻa ka potassium borohydride, akā hiki ke decompose i mua o ke kiʻekiʻe o ka wela, ka haʻahaʻa kiʻekiʻe a me nā mea hoʻomake ikaika.
ʻO ka hoʻohana nui ʻana o ka potassium borohydride he:
1. Ke kumu hydrogen: Hiki ke hoʻohana ʻia ka potassium borohydride ma ke ʻano he reagent no ka synthesis o ka hydrogen, i hana ʻia ma ka hana ʻana me ka wai.
2. Mea ho'ēmi kemika: Hiki i ka potassium borohydride ke hoʻemi i nā ʻano pūhui like ʻole e like me nā ʻona, nā aldehydes, a me nā ketones.
3. Metala lapaʻau ili: Potassium borohydride hiki ke hoʻohana no ka electrolytic hydrogenation lapaʻau o metala surfaces e hoemi ili oxides.
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka potassium borohydride ka nui o ke ʻano hoʻohaʻahaʻa pololei, ke ʻano antiborate a me ke ʻano hoʻohaʻahaʻa pauka alumini. I waena o lākou, loaʻa ke ʻano maʻamau i hoʻohana ʻia e ka hopena o ka sodium phenylborate a me ka hydrogen ma lalo o ka hana a kahi catalyst.
ʻO ka ʻike palekana o ka potassium borohydride penei:
1. Potassium borohydride i ikaika reducibility, a me ka hydrogen ke hana ia me ka wai a me ka waiʻakika, no laila, pono e hana ia ma ka maikai-ventilated wahi.
2. Hōʻalo i ka pili ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu e pale ai i ka huhū a me ka ʻeha.
3. I ka mālama ʻana a me ka hoʻohana ʻana i ka potassium borohydride, pono e mālama ʻia e pale i ka hoʻopili ʻana me nā oxidants a me nā mea ʻē aʻe e pale ai i ke ahi a pahū paha.
4. Mai hoʻohui i ka potassium borohydride me nā mea ʻakika e pale aku ai i ka hoʻokumu ʻana o nā kinoea weliweli.
5. I ka wā e hoʻolei aku ai i ka ʻōpala potassium borohydride, pono e mālama ʻia nā lula pili kaiapuni a me ka palekana.
