Mawu Oyamba
asidi ethyl ester ndi organic pawiri ndi mankhwala chilinganizo C8H8BrNO2. Ndi madzi opanda mtundu okhala ndi fungo lapadera. Mankhwalawa amasungunuka mu zosungunulira za organic monga ethanol, dimethylformamide ndi benzene, komanso osasungunuka m'madzi.
asidi ethyl ester ali osiyanasiyana ntchito mu kaphatikizidwe organic. Itha kugwiritsidwa ntchito ngati mankhwala apakatikati pakupanga mitundu yambiri yamankhwala ndi mamolekyu a bioactive. Kuphatikiza apo, itha kugwiritsidwanso ntchito muzochita za Gormperman ndi palladium-catalyzed cross-coupling reactions mu organic synthesis.
Pali njira ziwiri zodziwika bwino za acid ethyl ester:
1. Iwo analandira ndi zimene 6-bromopyridine ndi chloroacetate, ndiyeno hydrolyzed ndi zamchere pambuyo anachita.
2. Ndi 6-bromopyridine ndi chloroacetic acid ester reaction, acid chloride, ndiyeno muzichita ndi mowa kuti mupeze mankhwala.
Kusamala ndikofunikira mukamagwiritsa ntchito ndikusunga asidi ethyl ester. Ndi madzi oyaka moto ndipo amayenera kusungidwa pamalo ozizira, opanda mpweya wabwino, kutali ndi moto komanso kutentha kwambiri. Zida zodzitetezera zoyenera, monga magolovesi a labu ndi magalasi, ziyenera kuvalidwa panthawi yogwira ntchito. Ngati mumeza kapena kukhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.
