3-Cyano-4-methylpyridine (CAS#5444-01-9)

ʻO ka 3-Cyano-4-methylpyriridine he mea hoʻohuihui mea ola me ke ʻano kemika C7H6N2. Eia ka wehewehe kikoʻī o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

ʻAno:
-Nani: 3-Cyano-4-methylpyriridine he keʻokeʻo i ka melemele crystalline solid.
-Ka helu hoʻoheheʻe: ʻO kona helu heheʻe he 66-69 degere Celsius.
-Solubility: He haʻahaʻa ka solubility i ka wai a hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe, e like me ka ethanol, ether a me ka chloroform.

E hoʻohana:
-Ma keʻano he mea hoʻoheheʻe organik: 3-Cyano-4-methylpyriridine hiki ke hoʻohanaʻia ma keʻano he reagent no ka hoʻohuiʻana i nā meaʻokoʻa'ē aʻe, e like me nā pesticides, nā lāʻau lapaʻau a me nā kala.
-Ma ke ʻano he catalyst: Hiki ke hoʻohana ʻia ma ke ʻano he catalyst i kekahi mau hopena catalytic.

Kaʻina hoʻomākaukau:
Hiki ke hoʻomākaukau ʻia ka 3-Cyano-4-methylpyriridine e kēia mau ʻano:
1. ʻO ka pyridine a me ka acetonitrile e hana i ka cyanation reaction e hoʻohua i ka 3-cyanopyridine, a laila e hana i ka hopena methylation e hoʻoulu i ka 3-Cyano-4-methylpyriridine.
2. Hoʻopili ka Methyl pyridine me ka hydrogen cyanide e hana i ka 3-Cyano-4-methylpyriridine ma lalo o ka catalysis o ka alkali.

ʻIke palekana:
Nā waiwai kemika o3-Cyano-4-methylpyridineʻaʻole i aʻo piha ʻia, no laila pono e hahai i nā kaʻina hana kemika maʻamau. E hoʻohana i nā lako pale pilikino kūpono e like me nā mīkina lima pale, nā maka aniani a me nā ʻaʻahu keʻena hana i ka wā e hoʻohana ai. Pono e mālama ʻia a mālama pono ʻia e pale aku i ka pili ʻana me nā mea e like me nā oxidants ikaika. I ke kaʻina hana, pono e uku ʻia e pale i ka inhalation, pili ʻili a i ʻole ka ʻai ʻana. Inā loaʻa ʻole kahi ulia pōpilikia, pono e lawe ʻia nā hana lapaʻau pilikia i ka manawa. ʻO ka ʻike o ke kemika a me ka ʻike hoʻokolohua ma ka lawelawe ʻana i ka pūhui e hōʻoia i ka mālama pono ʻana. I mea e hoʻomaopopo hou ai i kona palekana, e ʻoluʻolu e nānā i nā kikoʻī ʻenehana palekana kūpono a i ʻole e nīnau i kahi loea.
