Mawu Oyamba
Benzidine (wotchedwanso diphenylamine) ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Benzidine ndi yoyera mpaka yopepuka yachikasu yolimba.
- Kusungunuka: kosasungunuka m'madzi, kusungunuka mu zosungunulira organic monga ma alcohols, ethers, ndi zina.
- Chizindikiro: Ndi electrophile yomwe ili ndi mawonekedwe a electrophilic substitution reaction.
Gwiritsani ntchito:
- Benzidine chimagwiritsidwa ntchito m'munda wa kaphatikizidwe organic. Itha kugwiritsidwa ntchito ngati zopangira komanso zopangira mankhwala monga utoto, utoto, mapulasitiki, ndi zina.
Njira:
- Benzidine amakonzedwa mwachizolowezi ndi kuchepetsa dinitrobiphenyl, kuchotsedwa kwa ma radiation a haloaniline, etc.
- Njira zamakono zokonzekera zimaphatikizapo kaphatikizidwe ka organic ka amines onunkhira, monga momwe gawo lapansi la diphenyl ether limathandizira ndi amino alkanes.
Zambiri Zachitetezo:
- Benzidine ndi poizoni ndipo angayambitse mkwiyo ndi kuwonongeka kwa thupi la munthu.
- Pogwira benzidine, chisamaliro chiyenera kutengedwa kuti pasakhale kukhudzana ndi khungu ndi kupuma, komanso zipangizo zodzitetezera monga magolovesi, magalasi otetezera, ndi masks otetezera ayenera kuvala ngati kuli kofunikira.
- Benzidine ikakhudza khungu kapena maso, iyenera kutsukidwa nthawi yomweyo ndi madzi ambiri.
- Mukasunga ndikugwiritsa ntchito benzidine, samalani kuti musakhudze zinthu zachilengedwe ndi ma oxidants kuti mupewe moto kapena kuphulika.
