Mawu Oyamba

4-Methyl-2-nitrophenol ndi organic pawiri ndi mankhwala chilinganizo C7H7NO3. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:

 

Chilengedwe:

4-methyl -2-nitrophenol ndi kristalo wolimba, woyera mpaka wonyezimira wachikasu, imakhala ndi fungo lapadera lotentha kutentha. Ndi pafupifupi osasungunuka m'madzi, koma amasungunuka mu zosungunulira za organic monga ethanol ndi ether.

 

Gwiritsani ntchito:

4-methyl -2-nitrophenol amagwiritsidwa ntchito kwambiri popanga organic synthesis. Chifukwa ali ndi m'malo awiri yogwira, hydroxyl ndi nitro, angagwiritsidwe ntchito ngati antibacterial agent, preservative ndi peroxide stabilizer. Kuphatikiza apo, amagwiritsidwanso ntchito popanga utoto, utoto ndi utoto wa fulorosenti.

 

Njira Yokonzekera:

4-methyl -2-nitrophenol imatha kupangidwa ndi nitration ya toluene. Choyamba, toluene ndi wothira anaikira sulfuric asidi pamaso pa asidi nitric ndipo anachita pa kutentha yoyenera kwa nthawi inayake kupeza mankhwala, amene kenako pansi masitepe wotsatira wa crystallization, kusefera ndi kuyanika potsiriza kupeza 4- methyl-2-nitrophenol.

 

Zambiri Zachitetezo:

4-Methyl-2-nitrophenol ndi mankhwala oopsa omwe amakwiyitsa komanso owononga. Kuyang'ana pa izo kungayambitse kuyabwa pakhungu, kuyabwa m'maso ndi kupuma movutikira. Choncho, poigwiritsa ntchito kapena kuigwira, muyenera kuvala zida zodzitetezera zoyenera, monga magolovesi, magalasi oteteza komanso zipangizo zotetezera kupuma kuti musagwirizane ndi kupuma. Kuonjezera apo, ndi chigawo choyaka moto ndipo chiyenera kusungidwa kutali ndi moto ndi kutentha. Panthawi yosungira ndi kunyamula, chisamaliro chiyenera kutengedwa kuti musasakanize ndi okosijeni ndi zoyaka. Popanda chithandizo choyenera, kungayambitse kuipitsa ndi kuwononga chilengedwe. Chifukwa chake, njira zoyenera zotetezera ziyenera kutsatiridwa kuti zitsimikizire kugwiritsa ntchito moyenera ndikutaya kwapawiri.
