Taw qhia
3,5-difluorophenylhydrazine hydrochloride yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Khoom: Nws yog soluble hauv dej thiab qee cov organic solvents xws li ethanol, methanol. Nws yog ib tug tsis muaj zog acidic tshuaj uas reacts nrog alkalis.
Siv:
3,5-difluorophenylhydrazine hydrochloride feem ntau yog siv los ua tus neeg sawv cev txo qis thiab activator hauv cov organic synthesis. Nws tuaj yeem siv rau kev sib txuas ntxiv, txo cov organic tebchaw xws li ketones, aldehydes, aromatic ketones, thiab lwm yam.
Txoj kev:
3,5-Difluorophenylhydrazine hydrochloride tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm hydroquinone thiab 2-chloro-1,3,5-trifluorobenzene. Feem ntau, hydroquinone reacts nrog ntau tshaj 2-chloro-1,3,5-trifluorobenzene nyob rau hauv alkaline tej yam kev mob kom tau 3,5-difluorophenylhydrazine. Los ntawm reacting nws nrog hydrogen chloride, 3,5-difluorophenylhydrazine hydrochloride tuaj yeem tau.
Cov ntaub ntawv kev nyab xeeb:
3,5-Difluorophenylhydrazine hydrochloride yog ib qho tshuaj uas feem ntau siv hauv cov chaw kuaj thiab kev tsim khoom. Cov txheej txheem tsim nyog yuav tsum tau ua raws li cov txheej txheem, thiab cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb, thiab cov tsho hauv chav kuaj yuav tsum hnav. Nws tsis muaj tshuaj lom, tab sis nws tseem yuav tsum tau zam los ntawm kev sib cuag nrog daim tawv nqaij, qhov muag, thiab nqus pa. Thaum kis tau, nws yuav tsum tau yaug sai sai nrog dej ntau thiab nrhiav kev kho mob sai. Thaum khaws cia, nws yuav tsum khaws cia kom deb ntawm qhov hluav taws kub thiab cov khoom siv hluav taws xob, thiab khaws cia rau hauv qhov chaw qhuav, qhov cua zoo.
