Hoʻolauna
ʻO ka 4-carboxylphenylboronic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 4-carboxylphenylboronic acid:
ʻAno maikaʻi:
- Ke ʻano: ʻO ka maʻamau keʻokeʻo a i ʻole ka pauka crystalline.
- Hiki ke hoʻoheheʻe ʻia: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka acetone.
- Nā waiwai kemika: Esterification, acylation a me nā hopena ʻē aʻe e hiki mai.
E hoʻohana:
- Ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe.
Hanana:
- Hiki ke loaʻa ka 4-Carboxylbenzylboronic acid e ka hopena esterification o ka waikawa benzoic me ka waikawa boric. ʻO nā ʻanuʻu kikoʻī e like me kēia: benzoic acid a me ka borate i hoʻomehana ʻia a hana ʻia i loko o kahi mea hoʻoheheʻe organik, a laila loaʻa ka huahana ma ka crystallization.
ʻIke palekana:
- ʻO ka 4-carboxylphenylboronic acid ka mea maʻamau i manaʻo ʻia he pūhui palekana, akā he mea nui naʻe e hoʻolohe i nā ʻano hana palekana kūpono.
- I ka hana ʻana, e pale i ka pili pono ʻana me ka ʻili a me nā maka. Inā pili, holoi koke me ka wai nui.
- I ka mālama ʻana, pono e mālama ʻia a maloʻo a mamao mai nā lapalapa a me nā kumu wela.
