Mawu Oyamba
O-bromophenylhydrazine hydrochloride. Makhalidwe ake ndi awa:
1. Maonekedwe: O-bromophenylhydrazine hydrochloride ndi yopanda mtundu mpaka kuwala kwachikasu crystalline ufa.
2. Kusungunuka: kusungunuka m'madzi, ethanol ndi chloroform, kusungunuka pang'ono mu ether.
3. Kukhazikika: Zimakhala zokhazikika kutentha kwa chipinda, ndipo zimakhala zosavuta kuwola pamene zimakhala ndi kuwala, kutentha kwakukulu ndi okosijeni.
4. Chemical reaction: o-bromophenylhydrazine hydrochloride amatha kuchitapo kanthu ndi copper(II) ayoni kuti apange madontho ofiira-bulauni kapena ofiirira.
Ntchito zazikulu za o-bromophenazine hydrochloride ndi izi:
1. Chemical reagent: o-bromophenazine hydrochloride angagwiritsidwe ntchito ngati kuchepetsa wothandizila, coordination reagent ndi zopangira organic synthesis.
2. Electrochemical applications: o-bromophenylhydrazine hydrochloride angagwiritsidwe ntchito pofufuza electrochemical ndi mabatire.
Kukonzekera njira ya o-bromophenylhydrazine hydrochloride:
Kukonzekera kwa o-bromophenylhydrazine hydrochloride nthawi zambiri kumachitika ndi zomwe bromophenylhydrazine ndi hydrochloric acid. Muzosungunulira zoyenera, bromophenylhydrazine imayimitsidwa mu acetic acid, ndiyeno hydrochloric acid imawonjezedwa pang'onopang'ono, ndipo mpweya umapezeka pambuyo pochita, ndipo o-bromophenylhydrazine hydrochloride ingapezeke pambuyo poyanika, crystallization ndi zina.
Zambiri Zachitetezo:
1. O-bromophenylhydrazine hydrochloride imafuna kusamala kuti musagwirizane ndi khungu ndi maso pakugwira ndi kusunga. Ngati mwakumana mwangozi, muzimutsuka nthawi yomweyo ndi madzi.
2. Pewani kulowetsa mpweya wa fumbi kapena njira yake panthawi ya opaleshoni kuti mupewe kupuma.
3. Pewani kukhudzana ndi zinthu zoyaka moto ndi ma okosijeni kuti mupewe moto kapena kuphulika.
4. Zinyalala ziyenera kutayidwa motsatira malamulo a m'deralo, ndipo ndizoletsedwa kutaya kapena kutulutsa mu chilengedwe mwakufuna kwake.
