Taw qhia
O-bromophenylhydrazine hydrochloride. Nws cov khoom yog raws li nram no:
1. Cov tsos mob: O-bromophenylhydrazine hydrochloride yog xim tsis muaj xim rau lub teeb daj crystalline hmoov.
2. Solubility: soluble hauv dej, ethanol thiab chloroform, me ntsis soluble hauv ether.
3. Stability: Nws yog qhov ruaj khov ntawm chav tsev kub, thiab yooj yim rau decompose thaum raug lub teeb, kub thiab oxidant.
4. Cov tshuaj tiv thaiv tshuaj: o-bromophenylhydrazine hydrochloride tuaj yeem hnov mob nrog tooj liab (II) ions los ua cov xim liab-xim av lossis xim av precipitates.
Kev siv tseem ceeb ntawm o-bromophenazine hydrochloride yog raws li hauv qab no:
1. Tshuaj reagent: o-bromophenazine hydrochloride tuaj yeem siv los ua tus neeg sawv cev txo qis, kev sib koom tes reagent thiab raw khoom rau cov organic synthesis.
2. Electrochemical daim ntaub ntawv: o-bromophenylhydrazine hydrochloride yuav siv tau rau electrochemical tsom xam thiab roj teeb.
Kev npaj ntawm o-bromophenylhydrazine hydrochloride:
Kev npaj ntawm o-bromophenylhydrazine hydrochloride feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm bromophenylhydrazine nrog hydrochloric acid. Hauv cov kuab tshuaj uas tsim nyog, bromophenylhydrazine raug tshem tawm hauv acetic acid, thiab tom qab ntawd cov concentration hydrochloric acid maj mam ntxiv, thiab precipitate tau txais tom qab cov tshuaj tiv thaiv, thiab o-bromophenylhydrazine hydrochloride tuaj yeem tau txais tom qab ziab, crystallization thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb:
1. O-bromophenylhydrazine hydrochloride yuav tsum tau ceev faj kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag thaum tuav thiab khaws cia. Nyob rau hauv rooj plaub ntawm kev sib cuag, yaug tam sim ntawd nrog dej.
2. Tsis txhob nqus cov pa ntawm nws cov plua plav lossis kev daws thaum lub sijhawm ua haujlwm kom tsis txhob ua pa tsis zoo.
3. Tsis txhob sib cuag nrog cov combustibles thiab oxidants kom tsis txhob muaj hluav taws kub los yog tawg.
4. Cov khib nyiab yuav tsum muab pov tseg raws li cov kev cai hauv zos, thiab txwv tsis pub pov tseg lossis pov tseg rau hauv ib puag ncig ntawm qhov xav tau.
