Taw qhia
3-Bromophenylhydrazine hydrochloride yog cov organic compound nrog cov tshuaj formula C6H6BrN2 · HCl. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
3-Bromophenylhydrazine hydrochloride yog ib qho khoom, dawb crystalline hmoov. Nws yog ruaj khov ntawm chav tsev kub, tab sis tej zaum yuav decompose nyob rau hauv siab kub los yog lub teeb. Nws solubility zoo, tuaj yeem yaj hauv dej. Nws yog ib qho tshuaj lom uas yuav tsum tau ua tib zoo tuav.
Siv:
3-Bromophenylhydrazine hydrochloride muaj qee yam kev siv nyiaj hauv cov txheej txheem ntawm cov organic synthesis. Nws tuaj yeem siv los ua ib qho reagent rau kev sib xyaw ntawm cov xim nruab nrab thiab cov synthesis ntawm cov tebchaw hauv kev lag luam tshuaj.
Txoj kev:
Ib txoj hauv kev zoo rau kev npaj 3-Bromophenylhydrazine hydrochloride yog thawj zaug ua ke 3-Bromophenylhydrazine, thiab tom qab ntawd hnov mob nrog hydrochloric acid kom tau hydrochloride.
Piv txwv li, 3-Bromophenylhydrazine tuaj yeem cuam tshuam nrog hydrochloric acid los ua 3-Bromophenylhydrazine hydrochloride.
Cov ntaub ntawv kev nyab xeeb:
Vim yog cov tshuaj lom ntawm 3-Bromophenylhydrazine hydrochloride, yuav tsum tau them nyiaj rau kev nyab xeeb thaum siv. Nws tuaj yeem ua rau tib neeg lub cev khaus khaus thiab ua rau ua pa ua pa thaum kov lossis nqus pa. Kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav tsum zam, thiab cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav thaum siv. Tsis txhob sib kis ntawm cov plua plav thiab cov khoom thaum lub sijhawm ua haujlwm, thiab xyuas kom meej tias qhov kev ua haujlwm tau zoo. Thaum muaj kev sib chwv tsis sib haum, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob. Thaum lub sijhawm khaws cia thiab tuav, cov cai tswj kev nyab xeeb yuav tsum tau ua raws.
