Hoʻolauna
He mea hoʻohuihui ia me ke ʻano kemika o C, H, BrN, O. Eia ka hoʻolauna ʻana i kekahi o kāna mau waiwai, hoʻohana, nā ʻano a me nā ʻike palekana.
ʻAno:
-Nani: ʻAʻohe kala i ka aniani melemele a i ʻole ka pauka.
-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik, e like me ka ethanol, dimethyl sulfoxide a me ka chloroform, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
-Kemika Synthetic: He ligand maʻamau ia, hiki ke hana i nā paʻakikī me nā metala hoʻololi a hoʻohana ʻia e like me nā catalysts i ka synthesis organik.
-Pesticide manufacturing: Hiki ke hoʻohana ʻia ma ke ʻano he waena no kekahi mau pesticides.
Hanana:
Hiki ke hana ʻia ke ʻano hoʻomākaukau e nā ʻanuʻu aʻe:
1. ʻO ka mua, ua hoʻoheheʻe ʻia ka lutidine i ka dimethyl sulfoxide.
2. Ma ka wela haʻahaʻa, e hoʻohui mālie i ka waikawa nitric me ka mālama ʻana i ka wela o ka hopena ma lalo o 0 degere Celsius.
3. Hoʻohui mālie i ka bromoethane Dropwise i loko o ka ʻōnaehana pane, hoʻomau i ka mālama haʻahaʻa haʻahaʻa, a hoʻoulu a hiki i ka hopena o ka hopena.
4. ʻO ka hope, kānana ʻia ka hui ʻana, holoi ʻia, crystallized a maloʻo no ka loaʻa ʻana o ka calcium.
ʻIke palekana:
Hiki iā ia ke hoʻopilikia i ke kino o ke kanaka a me ke kaiapuni, no laila pono ʻoe e makaʻala i nā pilikia olakino a palekana i ka wā e hoʻohana ai a mālama ai. Eia kekahi mau manaʻo palekana:
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā aniani a me nā lole pale ke hoʻohana ʻia.
-E pale i ka hanu ʻana i kona lepo a pili pū me ka ʻili. Inā loaʻa ka pilikia, holoi koke i ka wahi i hoʻopilikia ʻia me ka wai nui a ʻimi i ke kōkua olakino.
-E hoʻokaʻawale i nā kumu wela a me ke ahi i ka wā o ka mālama ʻana a me ka mālama ʻana, a mālama i ka ea maikaʻi.
- Hōʻalo i ka hoʻopili pololei ʻana me nā oxidants, acids, alkalis a me nā mea ʻē aʻe e pale aku i nā hopena pōʻino.
E ʻoluʻolu e hoʻomaopopo i ka ʻike i hāʻawi ʻia ma ʻaneʻi no ke kuhikuhi wale nō. I ka hoʻohana ʻana a me ka lawelawe ʻana i nā kemika ma ka hoʻomaʻamaʻa, e nānā pono i nā palapala kūpono a me ka mālama ʻana i nā lula palekana, a e hahai i ke alakaʻi ʻoihana.
