Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C5H5ClN2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
Ndi madzi opanda mtundu mpaka achikasu okhala ndi fungo lapadera. Ili ndi malo otsika otentha komanso osungunuka kutentha kutentha. Amasungunuka mu zosungunulira za organic monga diethyl ether, acetone ndi dichloromethane.
Gwiritsani ntchito:
Ndikofunikira organic wapakatikati, amene angagwiritsidwe ntchito kaphatikizidwe mankhwala ndi mankhwala. Amagwiritsidwa ntchito ngati wapakatikati pakupanga mitundu yosiyanasiyana ya mankhwala monga antiviral mankhwala ndi antitumor mankhwala. Kuphatikiza apo, itha kugwiritsidwanso ntchito pokonzekera zinthu zina zakuthupi, monga utoto ndi ma coordination compounds.
Njira:
Njira yopangira kashiamu imatha kupezeka pochita 2-methyl pyrimidine ndi thionyl chloride. Zomwe zimachitikira zimatha kusinthidwa molingana ndi zomwe zimayesedwa, koma zomwe zimachitika nthawi zambiri zimachitika pansi pa mlengalenga, kutentha kapena kutentha.
Zambiri Zachitetezo:
Ili ndi kawopsedwe wochepa pansi pamikhalidwe yogwiritsiridwa ntchito Mwachizoloŵezi, koma njira zoyenera zotetezera zimafunikirabe. Panthawi yogwira ntchito, kukhudzana ndi khungu, maso ndi kupuma kwa nthunzi kuyenera kupewedwa, ndipo magalasi oteteza ndi magolovesi ayenera kuvala ngati kuli kofunikira. Mukakumana ndi mankhwalawa, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala. Pa nthawi yomweyo, pewani kusakaniza ndi okosijeni amphamvu ndi zidulo amphamvu kupewa moto kapena kuphulika. Zosungira ziyenera kuyikidwa pamalo owuma, ozizira, opanda mpweya wabwino, kutali ndi moto ndi zoyaka.
