Hoʻolauna
ʻO ka 2-Bromo-5-chloropyridine kahi hui kūlohelohe, ʻo ia ka mea i hoʻolauna i kekahi mau waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-bromo-5-chloropyridine:
ʻAno maikaʻi:
1. Nani: 2-bromo-5-chloropyridine he kala ʻole a ʻeleʻele melemele.
3. Solubility: 2-bromo-5-chloropyridine maikaʻi ka solubility i nā mea hoʻoheheʻe organik maʻamau, e like me ka ethanol, acetone a me dimethyl thionite ether.
E hoʻohana:
1. ʻO nā reagents kemika: Hoʻohana pinepine ʻia ka 2-bromo-5-chloropyridine ma ke ʻano he reagent i ka synthesis organik.
2. Pesticide intermediates: Hoʻohana ʻia ia i ka synthesis o nā intermediates o nā pesticides e like me nā mea maka no nā insecticides a i ʻole herbicides.
Hanana:
Hiki ke loaʻa ka hoʻomākaukau ʻana o 2-bromo-5-chloropyridine e ka hopena o 2-chloropyridine me ka waika hydrobromic. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hoʻohemo ʻana i ka 2-chloropyridine i loko o ka cyclohexane anhydrous, hoʻohui i ka waika hydrobromic, hoʻomehana i ka hopena a me ka hoʻoulu ʻana, ma hope o ka pau ʻana o ka hopena, hoʻokaʻawale ʻia ka hopena organik me ka wai a me ka solution saturated sodium chloride, a hoʻomaʻemaʻe ʻia ka huahana i hoʻomaloʻo ʻia. lapaʻau a me ka distillation.
ʻIke palekana:
1. Loaʻa i ka 2-Bromo-5-chloropyridine nā hopena carcinogenic a me nā mea ʻawaʻawa i ka ʻōnaehana hānau, a pono e mālama i ka wā e hoʻohana ai.
2. E pale i ka pili me ka ili a me ka maka.
3. I ka hoʻohana ʻana a me ka mālama ʻana, pono e mālama ʻia mai ke ahi a me nā kumu wela.
4. Pono e mālama ʻia nā kūlana ventila maikaʻi i ka wā o ka hana.
5. Eʻoluʻolu e hahai pono i nā kaʻina hana palekana kūpono a hoʻohana i nā mea pale pilikino.
