Intangiriro

Ethyl 2, ni ifumbire mvaruganda hamwe na chimique C7H5Cl2NO2. Nibara ritagira ibara ryumuhondo rifite impumuro nziza.

Uru ruganda rukunze gukoreshwa nkibikoresho bigereranijwe kandi bibisi, kandi bifite uburyo bwinshi bwo gukoresha muri synthesis. Bikunze gukoreshwa mugutegura imiti yica udukoko, imiti n amarangi nibindi bikoresho. Mubyongeyeho, irashobora kandi gukoreshwa mukwiga reaction yimiti nimiterere ya Ethyl nikotinate.

Uburyo bwo gutegura Ethyl 2 nugukora aside 2,6-dichloropyridine-3-ya aside hamwe na Ethanol, mubisanzwe mubihe bya acide.

ethyl 2, harikibazo runaka cyumutekano. Numuti utera imbaraga ushobora gutera uburakari kumaso, uruhu na sisitemu yubuhumekero. Mugihe ukora, wambare ibikoresho birinda ubuhumekero, ibirahure birinda, uturindantoki turinda nibikoresho byo gukingira ibirenge. Byongeye kandi, ifite kandi ibyago byumuriro, igomba kuba kure yumuriro ufunguye nubushyuhe bwinshi.

Kubwimpamvu z'umutekano, mugihe ukoresheje Ethyl 2, kurikiza inzira za laboratoire kandi ukore ahantu hafite umwuka mwiza.

Mbere: Tetrapropyl ammonium chloride （CAS # 5810-42-4)
