Siv:
2-Nitrophenylhydrazine yog ib qho organic synthesis intermediate, dav siv nyob rau hauv kev npaj ntawm ntau yam organic tebchaw thiab dyes. Nws tuaj yeem siv rau hauv kev sib txuas ntawm carbamic bis (2-Nitrophenylhydrazine) cov khoom sib txuas ua cov xim nruab nrab thiab cov khoom ua ntej ntawm cov nplaim hluav taws.
Txoj kev:
2-Nitrophenylhydrazine tuaj yeem npaj tau los ntawm kev ua haujlwm 2-Nitrophenylhydrazine acid nrog cov neeg ua haujlwm txo qis, xws li sulfite lossis hydride. Cov kev mob tshwm sim tuaj yeem txiav txim siab raws li qhov xwm txheej.
Cov ntaub ntawv kev nyab xeeb:
2-Nitrophenylhydrazine tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv thaum raug thiab nqus tau. Nws yog irritating thiab tej zaum yuav ua rau ua pa ib ntsuj av khaus khaus, khaus qhov muag thiab khaus tawv nqaij. Tsis tas li ntawd, 2-Nitrophenylhydrazine kuj tseem suav tias yog cov kab mob carcinogenic thiab teratogenic. Yog li ntawd, siv ceev faj thiab siv cov kev tiv thaiv tsim nyog, xws li hnav hnab looj tes tiv thaiv, tsom iav kev nyab xeeb thiab cov cuab yeej tiv thaiv ua pa. Thaum khaws cia thiab tuav cov khoom sib xyaw, nws yuav tsum tau ua raws li cov txheej txheem kev ua haujlwm zoo.
