O-bromophenylhydrazine hydrochloride. Penei kona mau waiwai.
1. Nani: O-bromophenylhydrazine hydrochloride he kala ʻole i ka pauka crystalline melemele māmā.
2. Solubility: hiki ke hoʻoheheʻe i ka wai, ethanol a me ka chloroform, hiki ke hoʻoheheʻe iki i ka etera.
3. Paʻa: He mea paʻa ia ma ka lumi wela, a he maʻalahi ke hoʻoheheʻe i ka wā eʻikeʻia ai i ka mālamalama, ka wela kiʻekiʻe a me ka oxidant.
4. Ka hopena kemika: hiki i ka o-bromophenylhydrazine hydrochloride ke hana me nā iona keleawe (II) e hana i nā ʻeleʻele ʻulaʻula a ʻeleʻele paha.
ʻO nā hoʻohana nui o ka o-bromophenazine hydrochloride penei:
1. Kemika reagent: hiki ke hoʻohana i ka o-bromophenazine hydrochloride ma ke ʻano he mea hoʻohaʻahaʻa, coordination reagent a me nā mea maka no ka synthesis organik.
2. Nā noi uila: hiki ke hoʻohana ʻia ka o-bromophenylhydrazine hydrochloride no ka loiloi electrochemical a me nā pā.
ʻO ke ala hoʻomākaukau o ka o-bromophenylhydrazine hydrochloride:
ʻO ka hoʻomākaukau ʻana o ka o-bromophenylhydrazine hydrochloride e loaʻa pinepine ʻia e ka hopena o ka bromophenylhydrazine me ka waika hydrochloric. Ma kahi mea hoʻoheheʻe kūpono, hoʻokuʻu ʻia ka bromophenylhydrazine i ka acetic acid, a laila hoʻohui mālie ʻia ka waikawa hydrochloric, a loaʻa ka precipitate ma hope o ka hopena, a hiki ke loaʻa ka o-bromophenylhydrazine hydrochloride ma hope o ka maloʻo ʻana, crystallization a me nā ʻanuʻu ʻē aʻe.
ʻIke palekana:
1. Pono ʻo O-bromophenylhydrazine hydrochloride i ka mālama ʻana e pale aku i ka pili ʻana me ka ʻili a me nā maka i ka wā e mālama ai a mālama ʻia. Inā pili ʻole ʻia, holoi koke me ka wai.
2. E hō'ole i ka ho'ohu 'ana i ka mahu o kona lepo a i 'ole ka hopena i ka wā e hana ai i mea e pale aku ai i ka 'eha'eha o ka hanu.
3. Hōʻalo i ka hoʻopili ʻana me nā mea puhi ahi a me nā mea oxidants e pale i ke ahi a i ʻole pahū.
4. Pono e hoʻolei ʻia ka ʻōpala e like me nā kānāwai kūloko, a pāpā ʻia ka hoʻolei ʻana a hoʻolei ʻia paha i loko o ke kaiapuni ma ka makemake.
