Hoʻolauna
ʻO ka 4-Methyl-2-nitrophenol kahi mea hoʻohui kino me ke ʻano kemika C7H7NO3. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
ʻO 4-methyl -2-nitrophenol he mea paʻa, keʻokeʻo a hiki i ke aniani melemele māmā, he ʻala ʻala kūikawā kona ma ka lumi wela. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka etera.
E hoʻohana:
Hoʻohana nui ʻia ka 4-methyl -2-nitrophenol i ka synthesis organik. No ka mea he ʻelua mau substituent ikaika, hydroxyl a me nitro, hiki ke hoʻohana ʻia ma ke ʻano he antibacterial agent, preservative a me peroxide stabilizer. Eia kekahi, hoʻohana ʻia ia i ka hana ʻana i nā dyes, pigments a me nā dyes fluorescent.
Kaʻina hoʻomākaukau:
Hiki ke hana ʻia ka 4-methyl -2-nitrophenol e ka nitratation o toluene. ʻO ka mea mua, ua hui pū ʻia ka toluene me ka waikawa sulfuric concentrated i mua o ka waikawa nitric a hoʻololi ʻia i kahi mahana kūpono no kekahi manawa e loaʻa ai kahi huahana, a laila e hoʻokau ʻia i nā ʻanuʻu aʻe o ka crystallization, kānana a me ka hoʻomaloʻo ʻana a hiki i ka loaʻa ʻana o 4- methyl-2-nitrophenol.
ʻIke palekana:
ʻO 4-Methyl-2-nitrophenol kahi mea ʻawaʻawa e hoʻonāukiuki a ʻino. ʻO ka hoʻokuʻu ʻana iā ia e hoʻoulu ai i ka ʻili, ka ʻeha o ka maka a me ka ʻeha o ka ʻōpū hanu. No laila, i ka hoʻohana ʻana a i ʻole ka lawelawe ʻana, pono ʻoe e ʻaʻahu i nā mea pale kūpono, e like me nā mīkina lima, nā aniani pale a me nā mea pale hanu e pale aku ai i ka pili pololei a me ka inhalation. Eia kekahi, he mea puhi ia a pono e mālama ʻia mai ke ahi a me nā kumu wela. I ka wā o ka mālama ʻana a me ka lawe ʻana, pono e mālama ʻia e pale aku i ka hui ʻana me nā oxidants a me nā mea puhi. Ma lalo o ka mālama pono ʻole, hiki ke hoʻohaumia a pōʻino i ke kaiapuni. No laila, pono e hahai ʻia nā hana palekana kūpono e hōʻoia i ka hoʻohana pono ʻana a me ka hoʻolei ʻana i ka pūhui.
