Hoʻolauna
ʻO 2,2′-Bis(trifluoromethyl) -4,4′-diaminobiphenyl, i ʻike ʻia ʻo BTFMB, he mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: ka pauka crystalline keʻokeʻo
- ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i loko o ka ether a me benzene, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā waiʻona.
E hoʻohana:
- 2,2′-Bis (trifluoromethyl) -4,4′-diaminobiphenyl he mea koʻikoʻi koʻikoʻi koʻikoʻi, hoʻohana nui ʻia i ka synthesis o nā pūhui polymer a me nā polymers
- Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā polymers me ke kūpaʻa wela kiʻekiʻe, nā mea uila maikaʻi loa a me nā waiwai mechanical, e like me polyimide, polyetherketone, etc.
- Hiki ke hoʻohana ʻia ka BTFMB ma ke ʻano he mea maka no nā catalysts, coating additives, electrochemical material, etc.
Hanana:
- ʻO ka synthesis o 2,2′-bis(trifluoromethyl)-4,4′-diaminobiphenyl e hele maʻamau i ka hopena he nui.
- ʻO ke ʻano kikoʻī e pili ana i ka hydroxymethylation o ka methacrylonitrile me 4,4′-diaminobiphenyl e loaʻa ai kahi huahana waena, a ukali ʻia e trifluoromethylation e loaʻa ai ka huahana i manaʻo ʻia.
ʻIke palekana:
- 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl he mea hoʻohuihui mea ʻawaʻawa a hoʻonāukiuki paha.
- I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e hōʻalo ʻia ka hoʻopili ʻana me nā mea oxidizing ikaika a me nā waikawa ikaika
- I ka lawelawe ʻana a me ka hoʻolei ʻana i ka ʻōpala, e mālama i nā lula a me nā lula kūloko
