Hoʻolauna

He pūhui olaola me ke kumu C7H8N2O4S. He pauda crystalline keʻokeʻo me ka ʻakika nāwaliwali. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno:

-Nani: ʻO ka pauka crystalline keʻokeʻo

-Molecular kaumaha: 216.21g/mol

-kahi hoʻoheheʻe: 168-170 ℃

-Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai, maʻalahi e hoʻoheheʻe i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka acetone

-ʻakika a me ka alkaline: ʻakika nāwaliwali

 

E hoʻohana:

- hoʻohana nui ʻia i ka synthesis organik ma ke ʻano he reagent koʻikoʻi a me waena.

-Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea kemika e like me nā lāʻau lapaʻau, nā mea pena a me nā mea polymer.

 

Kaʻina hoʻomākaukau:

Hiki ke hoʻohui ʻia e nā ʻanuʻu aʻe: br>1. ʻO ka mea mua, ma lalo o nā kūlana hopena kūpono, hoʻopili ʻia ka methyl bromide a me ka p-nitrobenzene sulfonamide e hana i ka methyl ester.

2. A laila, hoʻopili ʻia ka methyl ester me ka waiʻona alkaline e loaʻa ai ka paʻakai.

 

ʻIke palekana:

-pono e mālama ʻia ma kahi maloʻo a maikaʻi-ventilated, a pale pono i ka lā.

-I ka wā o ka hana, e pale i ka pili ʻana me ka ʻili a me nā maka. Inā ʻike ʻia, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.

-E hoʻohana i nā mea pale pilikino kūpono e like me nā mīkina lima, nā aniani palekana a me nā lole pale i ka wā e lawelawe ai i ka pūhui.

-Mai hoʻohui i kēia pūhui me nā oxidants ikaika a me nā ʻakika ikaika, no ka mea hiki ke hoʻoulu i nā hopena weliweli.

-Ma mua o ka hoʻohana ʻana a i ʻole ka lawelawe ʻana i ka pūhui, pono e heluhelu pono ʻia nā ʻōlelo aʻoaʻo palekana i hāʻawi ʻia e ka mea hoʻolako.
