Hoʻolauna
ʻO 2-Chloro-6-methyl-5-nitropyridine he mea hoʻohui kūlohelohe maʻamau,
ʻAno maikaʻi:
- Ke ʻano: 2-chloro-6-methyl-5-nitropyridine he paʻa kala ʻole a melemele paha.
- Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, dimethylformamide a me ka chloroform.
E hoʻohana:
- Nā Kinohi: Hiki ke hoʻohana ʻia kēia pūhui e synthesize i kekahi mau mea hoʻonaninani ʻoihana, e like me ke ʻano o ka hale i ka waiwai o ka hoʻomoʻa ʻana i ke kukui UV, a hoʻohana nui ʻia i ka ʻoihana puaʻa a me ka ʻoihana.
Hanana:
Hiki ke loaʻa ka 2-Chloro-6-methyl-5-nitropyridine ma o ka chlorination a me ka nitrification o pyridine. ʻO ke ʻano hoʻomākaukau kikoʻī e hiki ke hoʻohana i ka waikawa nitric a me ka sulfuric acid e pane ai i ka loaʻa ʻana o ka waikawa nitrite, e hana i ka nitrite a me ke keleawe keleawe e hana i ka keleawe keleawe, a laila hoʻohana i nā mea hoʻoheheʻe electrophilic methylation (e like me ka methyl halogen) e hana me ke keleawe nitrate e loaʻa ai ka huahana i hoʻopaʻa ʻia.
ʻIke palekana:
ʻO 2-Chloro-6-methyl-5-nitropyridine kahi mea ʻawaʻawa e hoʻonāukiuki a weliweli. I ka hoʻohana ʻana a me ka lawelawe ʻana, pono e mālama pono e like me ke komo ʻana i nā maka pale, nā mīkina lima a me nā lole pale. E hōʻalo i ka hanu ʻana i kona mahu a i ʻole lepo, a pale i ka pili ʻana me ka ʻili a me nā maka. I ka hoʻohana ʻana i kēia pūhui, pono e mālama ʻia i kona kūpaʻa a pale aku i ka hoʻopili ʻana me nā kemika like ʻole. I ka wā e mālama ai, pono e mālama ʻia i loko o kahi pahu hau, ma kahi mamao o ka ignition a me nā oxidants.
