Mawu Oyamba
4-nitrobenzoylhydrazide ndi organic pawiri.
Ubwino:
4-Nitrobenzoylhydrazide ndi crystalline yachikasu kupita ku lalanje yomwe imasungunuka mu chloroform, ethanol, ndi zosungunulira za acidic, ndipo pafupifupi yosasungunuka m'madzi. Ndi yoyaka komanso yophulika ndipo iyenera kugwiridwa mosamala.
Gwiritsani ntchito:
4-nitrobenzoylhydrazide ndi reagent yamankhwala yomwe imagwiritsidwa ntchito ngati coupling reagent, amination reagent ndi cyanide reagent mu organic synthesis.
Njira:
Njira yokonzekera ya 4-nitrobenzoylhydrazide nthawi zambiri imagwiritsa ntchito zomwe benzaldehyde ndi hydrogen ammonia, yomwe imapangidwa ndi nitrified kupanga 4-nitrobenzaldehyde, ndiyeno 4-nitrobenzoylhydrazide imapezeka mwa kuchepetsa zomwe zimachitika.
Zambiri Zachitetezo:
4-Nitrobenzoylhydrazide ili ndi chiopsezo chachikulu chophulika ndipo chisamaliro chiyenera kutengedwa kuti musagwirizane ndi khungu ndi kupuma. Njira zodzitetezera ziyenera kuchitidwa panthawi yogwira ndi kusunga kuti zitsimikizire chitetezo. Mvetsetsani mosamala zambiri zokhudzana ndi chitetezo musanagwiritse ntchito: ndipo tsatirani njira yoyenera yogwirira ntchito ndikugwiritsa ntchito.
