Hoʻolauna
ʻO ka 2,3,5-Trifluoropyridine he mea hoʻohuihui kūlohelohe me ke ʻano kemika C5H2F3N. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
ʻO 2,3,5-Trifluoropyridine he wai kala ʻole me ka ʻala ʻala. He 1.42 g/mL kona mānoanoa, he 90-91°C, a me ka helu hehee -47°C. He hydrophobicity ikaika a paʻakikī ke hoʻoheheʻe i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, acetone a me xylene.
E hoʻohana:
Hoʻohana nui ʻia ka 2,3,5-Trifluoropyridine ma ke kahua o ka synthesis organik. Ma ke ʻano he fluorination reagent, hiki ke hoʻohana ʻia i nā hopena fluorination, a hoʻohana pinepine ʻia i ka hopena o ka hoʻokomo ʻana i nā ʻātoma fluorine. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he waena no ka synthesis o nā lāʻau lapaʻau, pesticides a me nā mea hoʻohui ʻē aʻe.
Kaʻina hoʻomākaukau:
ʻO 2,3,5-Trifluoropyridine ka nui o nā ʻano hoʻomākaukau, hoʻohana ʻia kekahi o ia mea e loaʻa ma ka reacting 2,3, 5-trichloropyridine me ka waika hydrofluoric. I ka wā o ka hopena, 2,3, 5-trichloropyridine e hoʻopili ʻia me ka waika hydrofluoric i loko o kahi mea hoʻoheheʻe kūpono, a mālama ʻia ka mahana hopena a me ka waiwai pH e loaʻa ai ka 2,3,5-Trifluoropyridine.
ʻIke palekana:
E noʻonoʻo i nā hana palekana i ka wā e lawelawe ai i ka 2,3,5-Trifluoropyridine. He mea ʻala ʻala ia e hoʻonāukiuki i ka ʻili, nā maka a me ka ʻōnaehana hanu. No laila, e pale i ka hoʻopili pololei ʻana me ka ʻili a me nā maka i ka wā e hoʻohana ai, a e hōʻoia i ka hana ʻana ma kahi maikaʻi-ventilated. I ka wā o ka mālama ʻana a me ka mālama ʻana, pono ia e hana i nā hana pale kūpono a pale i ka hoʻopili ʻana me nā mea oxidizing a me nā waikawa ikaika e pale ai i nā hopena pōʻino.
Eia kekahi, no ka hoʻohana ʻana i kekahi mea kemika, e ʻoluʻolu e hahai i nā kaʻina hana kūpono a me nā hoʻoponopono kūpono, a e nīnau i ke alakaʻi ʻoihana inā pono.
