Hoʻolauna

ʻO ka Dimethoxyaniline (N-methylaniline) kahi mea hoʻohui. He amine ia me kahi ʻano ʻona-amine a me kahi pKa ma kahi o 4.64. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka dimethoxyaniline:

 

ʻAno maikaʻi:

- Ke ʻano: ʻO Dimethoxyaniline kahi wai kala ʻole i ka wai melemele māmā.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik he nui, e like me nā waiʻona, ethers, a me nā hydrocarbons chlorinated.

- He mea ʻawaʻawa: He mea ʻawaʻawa ia, a ʻo ka ʻike ʻana a i ʻole ka inhalation ʻana o ka nui o nā mahu a i ʻole nā ​​wai hiki ke hōʻeha i ke olakino.

 

E hoʻohana:

- Hoʻohana nui ʻia ʻo Dimethoxyaniline ma ke ʻano he waena i ka synthesis organik.

- Hiki ke hoʻohana ʻia ma ke ʻano he catalyst e hoʻohui ʻia i ka ʻōnaehana hopena e hoʻomaʻamaʻa i kekahi mau hopena kemika.

- ʻO ka reactivity o ka dimethoxyaniline me nā pūhui ʻē aʻe, ʻo kona hopena me ka carbamate a me nā pūhui amide e lilo i mea nui i ka synthesis o nā pūhui hou.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka Dimethoxyaniline e ka hopena o ka aniline a me ka methanol. Hiki i nā hopena ma lalo o nā kūlana acidic, e like me ka hoʻohana ʻana i ka waika hydrochloric a i ʻole sulfuric acid ma ke ʻano he catalysts, hiki ke maʻalahi i ka hopena.

 

ʻIke palekana:

- He mea hoʻonāukiuki ka Lemonaniline i ka ʻili a me nā maka a hiki ke pōʻino i nā ʻōnaehana hanu a me ka ʻai.

- Pono nā hana kūpono e like me ke komo ʻana i nā mīkina lima pale, nā maka aniani, a me nā lole pale i ka wā e hoʻohana ai i ka dimethoxyaniline e hōʻoia i nā kūlana hoʻokolohua maikaʻi.

- I ka mālama ʻana a me ka mālama ʻana i ka bimethoxyaniline, e pale i ka hoʻopili ʻana me nā mea hoʻoheheʻe ikaika a me nā mea hiki ke puhi ʻia, a waiho i kahi anuanu, ea a maloʻo.
