Taw qhia
3,5-Dichlorophenylhydrazine hydrochloride yog siv dav hauv kev tshawb fawb tshuaj thiab kev sim. Nws tuaj yeem siv los ua ib qho reagent nyob rau hauv cov organic synthesis rau cov synthesis ntawm lwm cov tebchaw, tshwj xeeb tshaj yog cov synthesis ntawm nitrogen-muaj cov tebchaw. Nws kuj tseem siv tau los ua ib qho nruab nrab rau qee yam tshuaj.
Txoj kev npaj 3,5-Dichlorophenylhydrazine hydrochloride yog feem ntau tau los ntawm reacting phenylhydrazine nrog 3,5-dichlorobenzoyl chloride. Ua ntej, phenylhydrazine yog ntxiv yam tsis hnyav, thiab tom qab ntawd 3,5-dichlorobenzoyl chloride yog ntxiv maj mam los tsim cov khoom xav tau. Thaum kawg, cov khoom tau crystallized los ntawm kev sib ntxiv ntawm hydrochloric acid kom muab cov khoom ntshiab.
Hais txog cov ntaub ntawv kev nyab xeeb, 3,5-Dichlorophenylhydrazine hydrochloride tej zaum yuav muaj kev phom sij rau kev noj qab haus huv, yog li kev tiv thaiv tsim nyog yuav tsum tau ua thaum siv thiab tuav. Nws yog ib yam khoom ua rau khaus thiab yuav ua rau khaus rau lub qhov muag, tawv nqaij thiab ua pa. Nws raug nquahu kom hnav tsom iav tiv thaiv tsim nyog, hnab looj tes thiab lub ntsej muag tiv thaiv thaum lub sijhawm ua haujlwm kom ntseeg tau tias kev ua haujlwm tau ua tiav hauv qhov chaw muaj cua zoo. Tsis tas li ntawd, tsis txhob nqus nws cov plua plav lossis kev sib cuag ntawm daim tawv nqaij. Kev sib cuag nrog cov oxidants muaj zog thiab muaj zog acids yuav tsum zam thaum siv thiab khaws cia. Thaum muab pov tseg, nws yuav tsum muab pov tseg raws li cov cai hauv zos. Yog tias muaj kev tsis sib haum xeeb tshwm sim, kev ntsuas tam sim ntawd yuav tsum tau ua kom huv thiab daws nrog nws. Txawm li cas los xij, nws raug pom zoo kom siv raws li kev coj ua ntawm cov neeg ua haujlwm tsim nyog.
