Ethyl 2-methyl-5-nitronicotinate (CAS# 51984-71-5)

Mawu Oyamba

Ethyl, chilinganizo chamankhwala ndi C9H9NO4. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:

Chilengedwe:

Ethyl ndi kristalo wachikasu kapena ufa wokhala ndi mawonekedwe amafuta komanso fungo lapadera. Amasungunuka m'madzi ambiri osungunulira komanso osasungunuka m'madzi.

Gwiritsani ntchito:

Ethyl ndi organic synthesis wapakatikati pawiri, yomwe imagwiritsidwa ntchito kwambiri popanga mankhwala ophera tizilombo komanso kupanga mankhwala. Itha kugwiritsidwa ntchito popanga mitundu yosiyanasiyana yamankhwala omwe amapangidwa ndi biologically, monga mankhwala ophera tizilombo, fungicides, anti-chotupa mankhwala, etc.

Njira Yokonzekera:

Ethyl nthawi zambiri imakonzedwa ndi kaphatikizidwe ka mankhwala. Njira imodzi yodziwika bwino ndi esterification ya 2-methyl-5-nitronicotinic acid. Mu ntchito yeniyeni, 2-methyl-5-nitronicotinic acid imachitidwa ndi anhydride ndi alkaline chothandizira kupanga Ethyl.

Zambiri Zachitetezo:

Ethyl ikhoza kukwiyitsa khungu komanso kuvulaza maso, kupuma komanso kupuma. Choncho, njira zodzitetezera ziyenera kuchitidwa pogwira chinthucho, monga kuvala magolovesi ndi magalasi otetezera, kuonetsetsa kuti ntchitoyi ikuchitika pansi pa mpweya wabwino. Kuphatikiza apo, ziyenera kusungidwa pamalo owuma, ozizira, opanda mpweya wabwino, kutali ndi zoyaka ndi zowonjezera. Chonde onani zambiri zokhudzana ndi chitetezo ndi malangizo ogwiritsira ntchito pachitetezo chilichonse chokhudzana ndi mankhwalawa.
