2 3-DIBROMO-5-CHLORO PYRIDINE (CAS# 137628-17-2) hoʻolauna
ʻO 2,3-dibromo-5-chloropyridine kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau, a me ka ʻike palekana o ka pūhui:
ʻano:
-Nani: 2,3-dibromo-5-chloropyridine he kala ʻole i ka paʻa melemele.
-Solubility: He haʻahaʻa haʻahaʻa i loko o ka wai.
Ke kumu:
ʻO 2,3-dibromo-5-chloropyridine ka nui o nā noi i ka synthesis organik, i hoʻohana nui ʻia ma nā wahi aʻe:
-Ma keʻano he photosensitizer, hiki ke hoʻohanaʻia i nā kula e like me ka paʻi a me ka hana kiʻi.
ʻano hana hana:
Hiki ke hana ʻia ke ʻano o ka hoʻomākaukau ʻana o 2,3-dibromo-5-chloropyridine ma o nā pae aʻe:
Ma lalo o nā kūlana kūpono, e hana i ka 2,3-dibromopyridine me ka phosphorus pentachloride e hana i ka 2,3-dibromo-5-chloropyridine pentachloride.
A laila, e hana i ka pentachloride me ka sodium hydroxide a i ʻole nā hopena alkaline e loaʻa ai ka 2,3-dibromo-5-chloropyridine.
ʻIke palekana:
-ʻO ka hoʻohana ʻana a me ka hana ʻana o 2,3-dibromo-5-chloropyridine pono e hoʻokō ʻia i loko o kahi wahi e hoʻoheheʻe maikaʻi ʻia i mea e pale ai i ka ʻike lōʻihi i kona ʻala a lepo paha.
-I ka wā o ka hana, pono e ʻaʻahu ʻia nā mea pale kūpono, me nā mīkina lima pale kemika, nā maka aniani, a me nā lole pale.
ʻO -2,3-dibromo-5-chloropyridine no nā bromides organik a loaʻa kekahi mau mea ʻawaʻawa a me ka huhū. Pono e mālama ʻia a mālama pono ʻia e pale aku i ka pili ʻana me nā mea puhi ahi a me nā wela kiʻekiʻe.
-I ka hoʻohana ʻana a me ka hoʻokuʻu ʻana i kēia pūhui, e ʻoluʻolu e hahai i nā koi o nā kaʻina hana palekana a me nā kānāwai a me nā lula pili.
