ʻO Calcium Hydride (CAS: 7789-78-8) he hydride metala honua alkaline, ʻoiai ʻaʻole paʻa ma mua o ka lithium hydride, akā paʻa ma mua o nā borohydride metala alkali.ʻO ke kumu hoʻohālike kemika ʻo CaH2.ʻO 42.10 ke kaumaha molekala.Ke hoʻokuʻu ʻia i ka hau hau ea e hoʻokuʻu, a haʻalele ka calcium hydroxide.ʻO ka hapa o ka 1.9.ʻO ka mahana decomposition ma kahi o 600 ℃.He 816 ℃ ka helu hehee (hydrogen).I ka hui ʻana i ka wai, nā ʻakika carboxylic, nā waiʻona haʻahaʻa, hiki iā ia ke decompose e hana i ka hydrogen.Ka decomposition Ke loaʻa ka tempreture i 600 ℃, hoʻomaka ia e decompose.Ma ka lumi wela, ʻaʻole hiki ke hana me ka oxygen maloʻo, nitrogen, chlorine, akā hiki ke hana i nā wela kiʻekiʻe.Hiki i kēia hopena ke hoʻohua iā CaO, Ca3N2, CaCl2.Ma ka lumi wela, hiki iā ia ke hana me ka wai a ʻo ka huahana ka calcium hydroxide a me ka hydrogen.Hiki ke hoʻohana ʻia e like me ka mea hōʻemi a me ka condensing agent i ka synthesis organik, a me ka desiccant i ka hana ʻana i nā mea hydrogen.hoʻohana mau ʻia i loko o nā hale hana e hana i nā mea liʻiliʻi o ka hydrogen maʻemaʻe loa no nā hoʻokolohua.Hoʻohana ʻia e like me ka pauka metallurgy.ʻO nā mea hana hoʻohaʻahaʻa, ka mea hoʻomaloʻo kinoea a me nā mea hoʻoheheʻe kemika.ʻO ka hoʻohuihui ʻana.Hoʻohana ʻia ka calcium hydride ma ke ʻano he mea hoʻomaloʻo maikaʻi no nā mea hoʻoheheʻe paʻa kumu aprotic e like me nā ethers a me nā amine tertiary.He mea hoʻomaʻemaʻe maikaʻi ia i ka synthesis o nā aldehyde enamines i ka hua kiʻekiʻe a me ka maʻemaʻe.
Māhele: Nā mea pahū.
ʻO nā hiʻohiʻona pōʻino pahū: Ke hoʻomehana ʻia ka hopena me ka tetrahydrofuran, hiki iā ia ke hana i ka pahū;ke hui pū me ka potassium chlorate, hypochlorite, bromate, perchlorate, he mea wela ia, friction sensitive a pahū.
Nā ʻano o ka mālama ʻana: Pono ka waihona kālā e hoʻomaloʻo i ka wela haʻahaʻa;ʻaʻa haʻalulu, ʻaʻahu ʻaʻa, kūʻē i ka wela kiʻekiʻe.
