1,4-bis(4-aminophenoxy)benzene/3491-12-1cas:3491-12-1
ʻO ka 1,4-bis(4-aminophenoxy) benzene he mea hoʻohui kemika nui e paʻa ana i ka mea nui i nā ʻoihana like ʻole.ʻIke pū ʻia ʻo DABPA a i ʻole DAPB, ʻo kēia pūhui he amine aromatic mua e hōʻike ana i ke kūpaʻa wela a me ke kemika.ʻO C24H20N2O2 kona kumu mole, a he 368.43 g/mol kona nuipa mola.
Hōʻike ka wehewehe ʻana i ka huahana kumu i nā waiwai nui a me nā hiʻohiʻona:
1. Paʻa: 1,4-bis(4-aminophenoxy)benzene hōʻike i ka wela a me ka paʻa kemika maikaʻi loa, hiki iā ia ke kū i nā wela kiʻekiʻe a me nā kūlana kaiapuni paʻakikī.
2. Maʻemaʻe: Hanaʻia kā mākou huahana me ka hoʻohanaʻana i nā mea waiwai kiʻekiʻe a me nāʻenehana synthesis kiʻekiʻe, e hōʻoia ana i kahi kiʻekiʻe o ka maʻemaʻe a me ke kūlike.
3. Solubility: He liʻiliʻi ka hoʻoheheʻe ʻia o kēia pūhui kemika i ka wai akā hōʻike ʻia ka solubility maikaʻi i loko o nā mea hoʻoheheʻe organik, kūpono ia no nā ʻano hana like ʻole.
ʻAoʻao kikoʻī huahana:
Hāʻawi ka ʻaoʻao kikoʻī huahana i ka ʻike kikoʻī hou aku e pili ana i nā noi, nā pōmaikaʻi, a me nā alakaʻi hoʻohana o 1,4-bis(4-aminophenoxy)benzene:
1. Nā noi: Ma muli o kona kūpaʻa a me nā waiwai kūikawā, loaʻa kēia pūhui i nā noi i ka hanaʻana i nā polymers, e like me nā polyamides a me nā polyimides.Hoʻohana ʻia nō hoʻi ia i ka synthesis o nā dyes, pharmaceutical intermediates, a me nā kemika kūikawā.
2. Pono:
- ʻO ke kūpaʻa wela: ʻO ke kūpaʻa wela kiʻekiʻe o ka pūhui e lilo ia i mea hoʻohui maikaʻi i nā uhi pale wela a me nā mea hoʻohui.
- Ke kū'ē kemika: ʻO kona kūʻē kūʻokoʻa i nā kemika hiki iā ia ke hoʻohana ʻia i nā wahi corrosive like ʻole.
- Ka lōʻihi o ka mīkini: Nā huahana i hoʻokomo i ka 1,4-bis(4-aminophenoxy) benzene e hōʻike i ka ikaika a me ka lōʻihi.
3. Hoʻohana a me ka lawelawe ʻana:
- E like me nā mea kemika, pono e mālama pono ʻia ka mālama ʻana a me ka mālama ʻana.E ʻoluʻolu e nānā i ka Pepa ʻIkepili Palekana Mea (MSDS) no nā kuhikuhi kikoʻī.
- E mālama i ka hui ma kahi maloʻo a maloʻo, mamao mai nā mea like ʻole.
