Hoʻolauna
He pūhui mea ola ia me ke ʻano kemika C6H5ClN2O3.
ʻAno:
-Nani: Keʻokeʻo a ʻulaʻula melemele paʻa
-Lae hehee: 44-46°C
-Pila paila: 262°C
-Soluble i loko o: ka waiʻona a me ka etera, hiki ʻole ke hoʻoheheʻe ʻia i ka wai
E hoʻohana:
he mea koʻikoʻi koʻikoʻi, hoʻohana nui ʻia ma ke kahua o ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā ʻano mea like ʻole, e like me nā lāʻau lapaʻau, nā mea pena a me nā pesticides.
Kaʻina hoʻomākaukau:
Hiki ke hana ʻia ka Synthesis ma o nā pae aʻe:
1. Ua loaʻa ka 2-Nitro-6-formylpyridine ma ka hana ʻana i ka 2-nitro-6-nitro-pyridine me ka waikawa sulfuric.
2. Hoʻokumu ʻia ka hopena o 2-nitro-6-formylpyridine a me chloromethyl ether ma lalo o ka hana o ka alkali.
3. Hoʻomaʻemaʻe ʻia a me ka crystallization i hana ʻia no ka loaʻa ʻana o ka huahana maʻemaʻe.
ʻIke palekana:
He mea pōʻino e hoʻoulu ai i ka huhū a me nā hopena maʻi ma muli o ka ʻike a i ʻole ka inhalation. I ka wā e hana ai, e hoʻokomo i nā mea pale kūpono e like me nā mīkina lima, nā makaaniani a me nā lole pale, a e hōʻoia i ka hana ʻana o ka hana i loko o kahi ea maikaʻi. I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e pale ʻia ka hoʻopili ʻana me nā oxidants ikaika a me nā mea puhi ahi.
