Hoʻolauna

ʻO ka 2,6-dimethylpyridine kahi hui kūlohelohe. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,6-dimethylpyridine:

 

ʻAno maikaʻi:

ʻO 2,6-Dimethylpyridine he wai kala ʻole me kahi ʻala ʻala ikaika.

 

E hoʻohana:

Loaʻa i ka 2,6-Dimethylpyridine nā ʻano hana like ʻole:

1. Hiki ke hoʻohana 'ia ma ke 'ano he catalyst a me ka reagent i nā mea ho'ohehe'e synthesis.

2. Hoʻohana ʻia ʻo ia ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā dyes, fluorescents a me nā mea kūlohelohe.

3. Hoʻohana ʻia e like me ka solvent a me ka extractant, hoʻohana nui ʻia i nā hopena kemika nui a me ka ʻoihana lāʻau lapaʻau.

 

Hanana:

Hoʻokumu pinepineʻia ka 2,6-Dimethylpyridine e ka hopena o ka acetophenone a me ka ethyl methyl acetate.

 

ʻIke palekana:

1. He ʻala koʻikoʻi kona a pono e ʻalo ʻia no ka hoʻopili lōʻihi ʻana a pale i ka hoʻohu ʻana i nā kinoea a i ʻole nā ​​​​huhū.

2. Pono e ʻaʻahu ʻia nā mīkina lima pale kūpono, nā maka aniani a me nā lole pale i ka wā o ka hana.

3. Hōʻalo i ka hoʻopili ʻana me nā oxidants ikaika a me nā ʻakika ikaika e pale aku i nā hopena ʻino.

4. I ka wā e mālama ai, pono e hoʻopaʻa paʻa ʻia ka ipu, mai ke ahi a me ke ʻano wela kiʻekiʻe.
