maikaʻi
Nā aniani melemele ʻeleʻele. He 60 °C (58 °C) ka helu hehee, 283 °C, 112~115 °C (0.4kPa) ka helu ho'olapalapa, a he 1.1176. Hiki ke hooheheeia. etera. Hiki ke hoʻoheheʻe ʻia i ka etera, hiki ke hoʻoheheʻe ʻia i ka ethanol wela a me ka etera petroleum wela.
ʻano hana
Hoʻomākaukau ʻia e ka etherification reaction o p-nitrochlorobenzene a me ka ethanol. P-nitrochlorobenzene a me ka ethanol ua hoʻohui ʻia i ka ipu hoʻoheheʻe, ua hoʻokiʻekiʻe ʻia ka mahana i 82 ° C, a ua hoʻohui ʻia ka hopena sodium hydroxide ethanol dropwise, a ua lawe ʻia ka hopena ma 85 ~ 88 ° C no 3h. Ua ho'ēmiʻia ka alkalinity o ka hopena hopena ma lalo o 0.9%, hoʻomahaʻia i 75 ° C, a ua hoʻololiʻia ka pH waiwai i 6.7 ~ 7 me ka waika hydrochloric concentrated. Ma hope o ke kū ʻana a me ka stratification, lawe ʻia ka ʻaila ʻaila a holoi ʻia ka sodium nitrophenol e ka wai wela, a hoʻoheheʻe ʻia ka ʻaila ʻaila ma lalo o ke kaomi hoʻemi, a lawe ʻia ka hapa o 214 ~ 218 °C (2. 66 ~ 5.32kPa). e like me kēia huahana.
hoʻohana
hoʻohana ʻia ma ke ʻano he mea waena i nā lāʻau lapaʻau a me nā mea pena. Hoʻohana ʻia ia i ka lāʻau lapaʻau e synthesize phenacetin, etc.
palekana
He mea ʻawaʻawa kēia huahana. ʻO ka inhalation a me ka ʻai ʻana he mea pōʻino i ke olakino. E hoʻohana i nā makaaniani palekana, e ʻaʻahu i nā lole komo kūʻokoʻa i ka lāʻau make, a e hoʻokomo i nā pale huna huna hoʻohuihui ponoʻī i ka wā e pili ana me ka lepo.
Hana ʻia ka ʻeke me nā pahu kila hāmama liʻiliʻi, nā ʻōmole aniani o ka waha, nā poʻi hao kīʻaha kīʻaha waha, nā ʻōmole plastik a i ʻole nā pahu metala (kani) ma waho o nā pahu lāʻau. E kūʻai i loko o kahi hale kūʻai maʻalili. E mālama i ke ahi, ke kumu wela, pale i ka lā pololei, a hoʻopaʻa i ka ipu. ʻO ka hoʻouka māmā a me ka weheʻana i ka wā e lawelawe ai.
