2-Chloro-4 6-dimethylpyridine（CAS# 30838-93-8)

Hoʻolauna

ʻO 2-Chloro-4, 6-dimethylpyriridine he mea hoʻohuihui mea ola me ke ʻano kemika C7H9ClN. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

ʻAno:

-Nani: 2-Chloro-4, 6-dimethylpyriridine he wai kala ʻole a melemele iki.

-Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ether a me ka waiʻona.

-Density: ʻO kona mānoanoa ma kahi o 1.07 g/mL.

-Ka helu hoʻoheheʻe a me ka helu hoʻolapalapa: ʻO ka helu hoʻoheheʻe o ka hui ma kahi o -37 ° C, a ʻo ka helu hoʻolapalapa ma kahi o 157-159 ° C.

-Stability: He kūpaʻa ma ka lumi wela.

E hoʻohana:

- 2-Chloro-4, 6-dimethylpyriridine ka mea maʻamau i hoʻohana ʻia i ka synthesis organik ma ke ʻano he catalyst, waena a i ʻole nā ​​​​mea maka.

-Aia no hoi kekahi mau noi ma ke kahua o ka laau lapaau, no ka synthesis o kekahi mau laau.

Hanana:

Hiki ke loaʻa ka hoʻomākaukau ʻana o -2-Chloro-4,6-dimethylpyridine e ka hopena o 2-methylpyridine a me thionyl chloride. Hiki ke hoʻokō ʻia nā ʻano hopena me ka hoʻohana ʻana i kahi base inorganic, e like me ka potassium hydroxide a i ʻole sodium hydroxide, ma ke ʻano he catalyst a ma kahi mahana kūpono.

ʻIke palekana:

-2-choro-4, 6-dimethylpyridine hiki ke hoʻonāukiuki a ʻino, a pono e mālama i ka wā e pili ana me ka ʻili a me nā maka. Pono e ʻaʻahu ʻia nā mea pale pilikino e like me nā mīkina lima, nā maka aniani a me nā lole pale i ka wā e hoʻohana ai.

-E hōʻalo i ka hoʻohu ʻana i kona mahu i ka wā e hana ai. Inā nui ka hanu ʻana, pono e hoʻoneʻe ʻia i kahi ea hou. Inā loaʻa iā ʻoe kekahi pilikia a i ʻole nā ​​hopena ʻino, pono ʻoe e ʻimi i ka lāʻau lapaʻau i ka wā hiki.

-E ʻoluʻolu e hoʻokele a mālama pono i ka pūhui, ma kahi o ka wela a me nā kumu ahi, pono ka mahana o ka mālama ʻana ma waena o 2-8 ℃, a mamao aku i nā mea hoʻonā.

- I ka hoʻohana ʻana a i ʻole ka hoʻokuʻu ʻana, e ʻoluʻolu e nānā i nā lula pili a me nā alakaʻi hana palekana.
